What Is a Trailer Arm?

A trailer arm is a part of your vehicle’s suspension system that connects the rear axle to the chassis. It’s also responsible for distributing the weight of your vehicle as it turns.

When the bushings on a trailing arm wear out, they can make the front and rear wheels shift their allocation of weight from one side to the other. This can cause swaying over bumps and around turns.


Aside from being a great looking piece of engineering, the Trailer Arm also comes with a few nifty features. One of the more notable is that it’s adjustable. This feature allows you to fine tune your suspension in a way that is both safe and fun. Moreover, it will save you time and money in the long run as well.

The best part is that the feature works with all models and years of the vehicle. Moreover, it’s a direct replacement for your stock arms. This makes it a worthwhile upgrade to any muscle car. The aforementioned gizmo is a must have on your to do list if you’re serious about enhancing your ride and handling capabilities.

Lastly, the best part about it is that it comes with an awe-inspiring warranty. This means that you don’t have to worry about the quality of your new suspension piece. Besides, it’s made of high-grade aluminum so you’ll never need to replace it again. The warranty is good for as long as you own your ‘Meganic’. The aforementioned features make this the best value for your hard-earned money. Hence, it’s no wonder why this awe-inspiring item has already won its way to the top of our best-selling list.


When you buy a trailer, you need to know that it will be sturdy enough to carry the weight of your load. A good way to test this is to look at how the frame of the trailer holds up under load.

In general, the larger and heavier the load you plan to haul, the stronger the frame needs to be. It should be reinforced where the axles mount and there should be double layers of material in high stress areas like the front corners, back most bumper area and at the main beam connections to the trailer.

The rear most member should be strong to support loads that go over it and if it is not attached securely, the load may get into the frame and rot the main members or cause other problems. Gussets are also a good idea since they provide extra strength and rigidity.

Trailing arms are a visually striking part of a linked rear suspension, providing fabricators with an opportunity to add artistic flair to the design. They are usually attached to the chassis, rear axle and shocks.

They should be braced to prevent vertical flexing and can be made of laminated, stitch welded or tube material. If the trailing arm extends more than Trailer Arm a few feet, the material should be mitered and gusseted to the chassis rail to increase stiffness.

In addition, tongues should be braced to prevent bending under load. They need to be able to withstand the repeated loading and unloading of the trailer.

A tongue needs to be sized appropriately for the load it will carry and should be made of 2x RHS (Rectangular Hollow Section) pieces that are stitch welded together. This is the strongest design for a tongue.

The longer the tongue the less load it will be able to carry, so the length should be kept to a minimum and the tongue should Trailer Arm be fitted to the chassis with the longest edge vertical.

Jack stabilizers are an excellent choice because they are easy to install and don’t require any tearing down or stowing away. They can be used with scissor, electric or telescoping jack systems and attach directly to the RV frame.


A trailer’s suspension is one of its most vulnerable points, but there are a few ways to protect it and increase its longevity. First, choose a sturdy and robust articulating hitch that can withstand the rigors of a rough ride.

Another option is to select a shock-free suspension. Air suspensions are a popular choice for light-duty vehicles as they are easy to install, do not require heavy-duty springs and provide a quieter ride.

Torsion axles are also a good choice for heavier-duty trailers and can help reduce overall wear and tear on the frame. In addition, they can significantly increase the amount of travel.

Regardless of your preference, be sure to choose the best options for your needs. The right suspension system can make all the difference between a smooth and safe ride and a sloppy mess. So, get to work and find out for yourself which one is the best fit for you and your hauling needs.

Easy to Install

There are a few different types of trailer arms that you can use for your rear suspension. Some are easy to install while others require a little more work. However, all of them can be used to increase your vehicle’s ability to tow and also help prevent swaying.

The most common type of hitch arms are chain models that have steel tabs that connect to the tongue of your trailer. These are not only great for preventing swaying, but they’re also relatively inexpensive and can be easily installed. Some even have integrated sway control, so you don’t need to do any additional work on your trailer or truck.

Another type of hitch arm is an elongate model that includes a tow vehicle attachment end and an opposite trailer tongue attachment end. In addition, the hitch arm may include a tow vehicle mounting plate that extends horizontally from the trailer tongue attachment end.

Finally, an elongate frame member 14 is provided, with the trailing arm 22 depending from the forward portion 16. The forward trailer frame attachment end 24 of the suspension arm 22 has a pivot bracket 26 secured to the frame member 14. An axle support 30 can be located within the fork 22 to attach a wheel and tire assembly 32.

The trailing arm can be a very visually appealing component of the rear suspension. It’s also an important connection point for the chassis and rear axle. There are many different designs to choose from, so you can find one that works for your specific needs. But no matter what style you pick, it’s always a good idea to make sure that your frame and chassis are strong enough to take the weight of your trailer.
