Frequently Asked Questions

A trailer axle is a central shaft that supports the weight of your trailer and its cargo. It connects the trailer wheels, enabling them to rotate smoothly while bearing the load. Axles come in various types, including straight, drop, torsion, and more. Their capacity and configuration depend on the trailer's weight and purpose.

To begin with, knowing the parts of a trailer axle will be helpful to you when making a purchase. When buying axles and axle parts, take note of the accompanying diagram and definitions.

• Axle beam: A rigid piece of steel that connects a set of wheels; the foundation of your trailer suspension system
• Lugs: The nuts that are used in conjunction with bolts to secure the wheel to the trailer axle
• Attaching parts: Used to bolt leaf springs to onto the hangers
• Hangers: Used to mount the leaf springs onto the trailer
• Leaf springs: Made of several layers of metal that are curved upward and clamped together to form an integral part of the trailer’s suspension system by helping to support the weight
• U-bolts: Used to keep the leaf springs on a trailer’s suspension system together
• Shackles: Allow the leaf spring to change lengths as the trailer travels over different types of terrain
• Equalizers: Connect to the leaf springs; they rock to absorb road shock and smooth out your ride

Axle capacity depends on factors like trailer weight, load distribution, and usage. Our experts can help you choose the appropriate axle based on your trailer's specifications.

Load capacity is the weight rating for the axle.  That’s a max, and that number usually defines the total capacity of the trailer.  For multiple axles (like tandems), assuming axles are the same, simply add the capacities for a sum total.

Generally speaking, look for trailer axles with more capacity than you need.  Also, be sure to match springs and tires, because the real capacity is the lesser of Axle Capacity, Spring Capacity, or Tire Capacity.  Don’t get caught short.

Determining Your Trailer’s Load Limit

Once you understand these factors, you can start working toward determining the safest load limit for your trailer. First, locate the Federal Certification / VIN label on the front half of your trailer. It should be located on the left side. This label will show you your trailer’s GVWR and GWAR. Trailers with a GVWR of 10,000 pounds or less will have a vehicle placard located in the same spot as the VIN label. The placard will provide tire and loading information, as well as a note regarding the maximum cargo capacity. Cargo can be added to your trailer up to the maximum weight specified on the placard. Remember, the total weight of your fully loaded trailer can’t exceed the listed GVWR. Be sure to load your trailer properly and follow the proper air pressure recommendations listed on your trailer’s VIN label or Tire Placard.

The best way to know the actual weight of your trailer is to use a public scale. Your dealer is your best resource for learning the best methods to follow for determining the weights related to your trailer, including weight empty or unloaded, weights per axle, hitch or king-pin, and total weight.

For trailers over 10,000 pounds GVWR, first determine the empty weight of your trailer. Then, find the GVWR on the VIN label. Subtract the empty weight of your trailer from the GVWR listed. The resulting number will be the maximum available cargo capacity of the trailer. Do not exceed this number.

We offer a range of axles, including straight axles, drop axles, torsion axles, and more. Each type serves different purposes, so choosing the right one depends on your trailer's design and usage.

Observe the example.  A straight beam with hubs at each end is what you would expect to see as a straight axle.  The trailer can simply sit 4 inches lower with a drop axle when using a leaf spring style.

Axles on trailers with a torsion design respond to drops differently.  The No-Load Arm Start Angle causes a lift or a drop.  This is a factory setting for some axles.  Others adjust.  In either case, it's vital to make sure the torsion axle you choose has the proper angle.  When the angle is "UP," a slight "drop" is achieved.  In contrast, providing the trailer a "lift" if the angle is "DOWN"

COMMON SIZES OF AXLES

You may select the ideal fit for your utility trailer by being aware of your axle specifications and the various spring axle options. The tag from the trailer manufacturer, which is located on the tongue or neck of the trailer, is the best place to look for the appropriate replacement axle for your trailer. This tag will include the weight capabilities required to buy a replacement axle as well as the trailer's VIN number. There should be a tag on the axle itself that has all the essential replacement purchase details.

There are a couple alternative ways to accurately measure for your axle replacement if you didn't buy your trailer from a firm or can't find the tag, which we've included below.

How to Measure Trailer Axle Length

The distance between the exterior of one hub and the exterior of the hub on the other side of the axle is known as the hub face. The distance between the centers of the spring seats on either side of the axle, known as the spring center, is measured. Hub face distance, a forward slash, and spring center distance are used to indicate axle lengths. For instance, an axle might be written as 58/46 if the hub face distance was 58 inches and the spring center was 46 inches.

Common Trailer Bolt Patterns & How to Measure Them

Axles are frequently divided into groups according on the type of suspension they have, such as Leaf Springs, Coil Springs, Torsion, Air Ride, Rubber Compression, Axle-less, Trailing Arm, Walking Beam, and the Odd or Unique trailer suspension.  Axle suspension comes in a huge variety of forms (or rigid mount without any suspension at all). 

Just a few, though, are actually typical.  Since they are the most typical, the leaf spring and torsion types will be covered in this article.  The information in this article is largely applicable to everybody, despite the many similarities.  If you're thinking about one of the other types, just disregard the things that don't apply because they don't matter for that type.  

The illustration depicts two trailer axles, one with the springs installed on top (also known as overslung), and the other with the springs mounted underneath (also known as underslung), as it is simpler to portray than to explain.  The trailer bed height is significantly affected by this.  In a limited way, it also has an impact on stability. 

These phrases frequently refer to Leaf Spring axles, although they can also refer to other, less prevalent suspension systems.

The options of "High or Low" and "Inside or Outside" brackets are somewhat comparable for torsion axles.  

Trailer brakes are crucial for enhancing safety and control while towing. They help reduce stopping distances and prevent wear and tear on the towing vehicle's brakes. Different brake types, such as electric, hydraulic, and surge brakes, offer varying levels of braking power based on the trailer's weight and the driver's preferences.

Trailer brakes are essential for safe towing, especially when hauling heavy loads. They help reduce stopping distances and prevent excessive strain on your towing vehicle's brakes.

Trailer brakes are an essential component of towing systems, as they help control the movement of trailers and improve overall safety when hauling heavy loads. 

Electric brake axles and hydraulic brake axles are both types of braking systems used in vehicles, particularly trailers and caravan applications, to assist in stopping and controlling the movement of the vehicle. Let's take a closer look at each type:

1. Electric Brake Axle: An electric brake axle utilizes an electric brake system to assist in stopping the vehicle. This system consists of electric brake assemblies mounted on the axles of the vehicle. When the driver applies the brakes in the towing vehicle, an electric signal is sent to the electric brakes on the trailer, causing them to activate and apply braking force to the trailer's wheels.

The electric brake system allows for proportional braking, meaning that the braking force applied to the trailer can be adjusted based on the deceleration of the towing vehicle. This results in smoother and more controlled braking, especially when the towing vehicle and trailer have varying weights.

Electric brake systems typically require a brake controller installed in the towing vehicle. This controller allows the driver to adjust the braking force applied to the trailer's brakes and provides the necessary electric signal for the trailer's brakes to activate.

2. Hydraulic Brake Axle: A hydraulic brake axle uses a hydraulic braking system to achieve braking. In this system, hydraulic fluid is used to transmit force from the brake pedal in the towing vehicle to the trailer's brake assemblies. When the driver presses the brake pedal, hydraulic pressure is generated and transmitted through brake lines to the trailer's brake units, causing them to activate and apply braking force to the trailer's wheels.

Hydraulic brake systems offer effective braking performance and are commonly used in larger trailers and caravans. They often have a master cylinder in the towing vehicle, which is connected to the trailer's brake system via hydraulic lines. Hydraulic systems provide a more direct and immediate connection between the brake pedal and the trailer's brakes.

Comparing the Two:

• Control: Electric brake systems often offer more fine-tuned control and adjustability, especially when towing vehicles and trailers have different weights. Hydraulic systems can be effective but might lack the same level of adjustability.

• Installation: Electric brake systems require a brake controller installation in the towing vehicle, which might add some complexity to the setup. Hydraulic systems require a hydraulic line connection between the towing vehicle and the trailer.

• Maintenance: Both systems require regular maintenance to ensure proper function. However, hydraulic systems might require additional attention to the hydraulic fluid and lines.

Ultimately, the choice between electric and hydraulic brake axles depends on factors such as the size and weight of the trailer, towing preferences, and local regulations. It's important to consider the specific requirements and characteristics of your towing setup before making a decision.

I currently have a hydraulic brake axle set up. Can I easily switch over to an electric brake axle set up?

- You can, of course. Simply buy the electronic brake axles, that's all. Once you have your axles, you will cut the hydraulic pump's wires and connect the brake power wire and ground wire to the electric brake axles from those wires (usually, the brake power wire is black and the brake ground wire is white).

Installing trailer brakes involves several steps to ensure safety and proper functionality. If you're not experienced with automotive or trailer work, it's recommended to have a professional handle the installation.

If you're uncertain about any step, it's safer to consult a professional mechanic or trailer technician. Properly functioning trailer brakes are crucial for the safety of you, your vehicle, and other road users.

Properly using your trailer brakes is essential for safe towing and driving. The method you use will depend on the type of trailer brakes you have: electric brakes or hydraulic brakes. Here's a general guide for both types:

**Electric Trailer Brakes:**

1. **Connection:** Ensure that your trailer is properly connected to your towing vehicle. The electrical connection between your vehicle and the trailer is crucial for controlling the trailer brakes.

2. **Brake Controller:** Your towing vehicle should be equipped with an electronic brake controller. This device allows you to adjust the amount of braking force applied to the trailer brakes. Most brake controllers have settings for gain (brake force) and sensitivity.

3. **Setting the Brake Controller:**
   - Start by adjusting the gain. This determines how much braking force is applied to the trailer when you engage the brakes in your towing vehicle. Start with a low setting and gradually increase it while testing the brakes until you find the right balance between vehicle and trailer braking.
   - Adjust the sensitivity setting if your brake controller has one. This setting determines how quickly the trailer brakes engage after you apply the vehicle brakes.

4. **Testing:** Find a safe and open space to test your trailer brakes before hitting the road. Accelerate your vehicle to a moderate speed and then apply the vehicle brakes. Observe how the trailer responds. The goal is to have the trailer braking smoothly without causing it to sway or jerk.

5. **Fine-Tuning:** Continue adjusting the gain and sensitivity settings as needed. The ideal setting will provide efficient braking without causing the trailer to push against the towing vehicle.

**Hydraulic Trailer Brakes:**

Hydraulic brakes are a different system that relies on the trailer's momentum to engage the brakes when the towing vehicle slows down. Here's how to use them:

1. **Connection:** Ensure your trailer is properly connected to the towing vehicle.

2. **Break-In Period:** New hydraulic brake systems might require a break-in period to function optimally. Refer to the manufacturer's instructions for any specific recommendations.

3. **Driving:** While driving, if you need to slow down or stop, apply the towing vehicle's brakes smoothly and steadily. The trailer's surge brakes will engage due to the forward momentum of the trailer pushing against the hitch, applying braking force.

4. **Testing:** Before your trip, test the hydraulic brakes in a controlled environment to get a sense of how they respond. Make sure they engage smoothly and help the trailer come to a controlled stop without jerking.

5. **Maintenance:** Keep the hydraulic brake system well-maintained, ensuring that it's properly lubricated and in good working condition.

Always refer to the specific instructions provided by the manufacturer of your trailer and towing vehicle for accurate information on using your trailer brakes effectively and safely. Additionally, be sure to comply with any local laws or regulations related to towing and braking systems.

Choosing the right tires and wheels for your trailer is essential for ensuring safe and efficient towing. Here are the steps to help you make the right decision:

What's the significance of load range and tire rating?

Load range and tire rating are important specifications for tires, especially in the context of vehicles such as cars, trucks, and trailers. They provide information about a tire's capacity to handle weight and its overall performance characteristics. Let's delve into each of these terms:

1. Load Range: The load range of a tire indicates its maximum load-carrying capacity and is usually designated by a letter, such as "C," "D," or "E." These letters correspond to specific load-carrying capacities, with "C" being lower than "D," and so on. The load range is often associated with light trucks and commercial vehicles.

For example, in a tire with a load range "C," the tire is designed to carry a certain maximum load at a specific inflation pressure. If the vehicle's load exceeds this capacity, it could lead to issues like tire overheating, reduced handling, and potentially even tire failure. Load range also correlates with the tire's construction, including the number of plies and the type of materials used, to ensure it can handle the specified loads safely.

2. Tire Rating: Tire ratings, often referred to as speed and load indexes, provide information about a tire's maximum speed capability and load-carrying capacity. These ratings are typically found on the sidewall of the tire. The speed rating is represented by a letter, and it indicates the maximum safe speed the tire can sustain for an extended period without overheating or experiencing significant wear.

The load index is represented by a number and corresponds to a specific load-carrying capacity for the tire. This number can be cross-referenced with a load index chart to determine the maximum weight the tire can support at a specified inflation pressure.

It's important to note that both load range and tire rating are interrelated. A tire's load-carrying capacity is directly influenced by its load range and construction. The tire rating, on the other hand, informs you about the tire's speed capabilities and load limits within its load range capacity.

In summary, understanding load range and tire rating is crucial for ensuring your vehicle's safety and optimal performance. Using tires with the appropriate load range and rating for your vehicle's weight and speed requirements helps prevent issues like blowouts, poor handling, and compromised stability. Always consult your vehicle's manual and tire manufacturer's guidelines to select the right tires that match your vehicle's specifications.

Trailer suspension refers to the system of components and mechanisms designed to support and manage the weight of a trailer while providing a smooth and controlled ride. Trailers are often towed behind vehicles such as trucks, SUVs, or cars, and they can carry a wide range of loads, from cargo to recreational equipment. The suspension system plays a crucial role in ensuring the stability, safety, and overall performance of the trailer while it's in motion.

Key components of a trailer suspension system include:

1. Leaf Springs or Coil Springs - These are the primary load-bearing components that support the weight of the trailer. Leaf springs consist of multiple layers of curved metal strips that flex to absorb shocks and distribute the weight evenly. Coil springs are helical-shaped springs that provide a more cushioned ride.

2. Axles - Axles are responsible for connecting the wheels of the trailer and distributing the trailer's weight to the wheels. They are usually equipped with bearings and hubs to allow the wheels to rotate smoothly.

3. Shock Absorbers (Dampers) - Shock absorbers are designed to dampen the oscillations caused by the movement of the trailer over uneven surfaces. They help prevent excessive bouncing and provide better control over the trailer's movement.

4. Suspension Linkages and Arms - These components connect the axles to the trailer frame and allow for vertical movement. They play a role in absorbing shocks and vibrations and maintaining stability during turns and uneven terrain.

The importance of a well-functioning trailer suspension system:

1. Load Distribution - A properly designed suspension system helps distribute the weight of the load evenly across the axles and wheels. This prevents overloading any single wheel and maintains proper balance, reducing the risk of accidents and tire wear.

2. Smooth Ride - A good suspension system absorbs shocks and vibrations caused by bumps, potholes, and rough roads. This not only improves the comfort of the passengers or cargo but also helps protect the trailer's structure from excessive stress.

3. Stability - The suspension system contributes to the trailer's overall stability, making it less prone to swaying, pitching, or rolling. This is particularly important when towing heavy or bulky loads, as improper suspension can lead to loss of control.

4. Tire Wear - A well-functioning suspension system helps maintain proper tire contact with the road, reducing uneven tire wear and prolonging the life of the tires.

5. Safety - A properly functioning suspension system improves the handling and control of the trailer, enhancing safety during braking, acceleration, and cornering.

In summary, trailer suspension is a critical component of any trailer, as it ensures the smooth and safe operation of the trailer, maintains load distribution, and minimizes the impact of road irregularities on the trailer and its cargo. Proper maintenance and selection of the appropriate suspension system for the trailer's intended use are essential for optimal performance and safety.

A trailer suspension system is designed to absorb shocks and vibrations generated by uneven road surfaces and movements of the towing vehicle. Its primary purpose is to provide a smoother and more stable ride for the trailer and its cargo, while also reducing stress on both the trailer and the towing vehicle. Here's how a trailer suspension system works and why it's important:

1. Shock Absorption: Roads are rarely perfectly smooth, and trailers can encounter bumps, potholes, and other imperfections that lead to jolts and vibrations. The suspension system includes components like springs and shock absorbers that absorb and dissipate these shocks, preventing them from being directly transmitted to the trailer frame and cargo. This helps protect the cargo from damage and reduces the wear and tear on the trailer itself.

2. Stability: A good suspension system helps maintain the stability of the trailer. When the trailer encounters an uneven surface, the suspension allows the wheels to move independently of each other. This helps prevent situations like trailer sway or bouncing, which can lead to loss of control and accidents.

3. Improved Handling: A properly functioning suspension system contributes to better handling of the trailer. It helps maintain proper tire contact with the road, which in turn improves braking, cornering, and overall maneuverability.

4. Reduced Fatigue: Both the trailer and the towing vehicle experience less stress and fatigue on their components when a suspension system is in place. This can extend the lifespan of the equipment and reduce maintenance costs over time.

5. Protection of Cargo: Trailers often carry valuable or sensitive cargo. A suspension system helps minimize the risk of damage to this cargo by absorbing shocks and vibrations. This is particularly important for fragile or perishable items.

6. Comfort: For trailers designed to carry passengers or provide living quarters (such as RVs), a suspension system improves the comfort of the occupants by reducing the impact of road vibrations and shocks.

There are various types of trailer suspension systems, including leaf spring suspension, torsion suspension, and air suspension. The choice of suspension system depends on factors like the trailer's intended use, load capacity, and desired level of comfort.

In summary, a trailer suspension system is a crucial component that contributes to a smoother, more stable ride for the trailer and its cargo, better handling, reduced wear and tear, and increased safety for both the trailer and the towing vehicle.

Trailer suspension systems play a crucial role in providing a smooth and stable ride for trailers, which can vary in size and purpose. There are several types of trailer suspension systems, each with its own characteristics and suitability for different applications. Here are some common types:

1. Leaf Spring Suspension: Leaf springs are a traditional suspension system consisting of multiple stacked metal leaves. This system offers durability and is commonly used in utility trailers, horse trailers, and some types of recreational trailers. Leaf springs provide decent load-bearing capacity and are relatively cost-effective.

2. Torsion Axle Suspension: Torsion axles use rubber cords or rods within the axle to provide suspension. This system offers a smoother ride compared to leaf springs, as each wheel is effectively independent. Torsion axles are often used in lightweight and smaller trailers, like enclosed cargo trailers and some travel trailers.

3. Air Suspension: Air suspension utilizes airbags to support the trailer's weight. This system allows for adjustable ride height, improved shock absorption, and the ability to level the trailer when parked. Air suspension is commonly found in larger trailers, such as semi-trailers, RVs, and heavy-duty equipment trailers.

4. Rubber Torsion Suspension: Similar to torsion axle suspension, rubber torsion suspension employs rubber cords to provide suspension and dampening. This system is known for its durability, low maintenance requirements, and smooth ride. It's commonly used in horse trailers, small RVs, and some boat trailers.

5. Independent Suspension: Independent suspension systems allow each wheel to move independently, resulting in better handling and improved shock absorption. These systems can be found in high-end travel trailers, luxury RVs, and off-road trailers where a smoother ride and better maneuverability are desired.

6. Slipper Spring Suspension: Slipper springs are a type of leaf spring suspension where one end of the spring is attached to the trailer frame, and the other end slides along a hanger. This design is often used in light to medium-duty trailers, such as utility trailers and boat trailers.

7. Equalizer Beam Suspension: This suspension system employs a combination of leaf springs and an equalizer beam that distributes the load and provides a smoother ride. It's commonly used in tandem axle trailers.

8. Swing Arm Suspension: Swing arm suspensions use a pivoting arm mechanism to provide suspension movement. They are often found on off-road trailers and heavy-duty utility trailers.

9. Rubber Block Suspension: Rubber block suspensions use blocks of rubber as the main suspension element. They are known for their simplicity and are used in some lightweight trailers.

The choice of suspension system depends on factors such as the trailer's intended use, weight capacity, ride comfort, terrain, and budget. It's important to select the right suspension system to ensure safe and efficient towing while meeting the specific needs of your trailer.
