Anti-sway bars help stabilize the vehicle in curves and prevent it from swaying. These bars give RVs more maneuverability, especially when passing other vehicles. The RV's structure will be more stable if there is no sway. This will also prevent unnecessary wear and tear.

Your vehicle's suspension includes your wheels/tires, shocks and steering system. It also includes your linkages, bushings and joints. Sway bars make it easier for your vehicle to turn and prevent body lean. This is a very important feature when operating a motor coach, RV or motorhome.

What do sway bars do?

As stated above, a swaybar is designed to prevent vehicle lean, which is usually caused by turning. A vehicle, especially a large one like a truck, or motor coach, turns when force is distributed outside.

 If you were turning left, force and weight would naturally shift to the right. This causes the tire on the outside to rise higher than the one on the inside. The sway bar allows the tires to be brought back to their original level, leveling the whole vehicle.

The sway spring acts as a torsion spring and reacts to twisting movements to level your vehicle's wheels. A sway bar would not be necessary if both tires struck something at the same time, as there would be no twisting motion.

Sway bars are essential for ensuring your vehicle doesn’t roll when turning. Sway bars are important for safety and better road grip.


You now know the importance of a swing bar. The question is, "Do you need one?" You can read more about it here.

It is best to take your vehicle to a qualified mechanic to find out if it needs a new swaybar. You can also use this page to check for any other issues.

You should pay attention to rattling and clunking sounds coming from your suspension, especially when you are going over bumps. Poor handling is also a concern.


Motor coaches are large enough to lean quite a lot without the use of sway bars. Driving an RV without a bar can be hazardous. Large vehicles with lots of wind pushing you to one side and the other side can cause a full body workout for the driver.

So, if you're planning on hitting the open road, a sway bar can be useful to alleviate some of that force and provide a smoother, more enjoyable ride.

It doesn't matter if you have a swaybar or not. It's which type you need. It all comes down to personal preference. If you are unhappy with the way your vehicle handles turns or high winds, talk to a mechanic and ask about a rigider or more flexible sway bar.


To create stability, anti-sway bars are made from the RV's weight. The bars are attached to the chassis and frame of the vehicle. Similar work is done for trailer tongue and hitch anti-sway bars.

These bars reduce vehicle's side to side motion by bracing its axle against the chassis. They distribute the recreational vehicle’s weight evenly. Each bar holds the vehicle in place when it is hit by wind gusts.

Turning and Passing

You will tire from wriggling the steering wheel around to adjust the RV's swaying. It is risky to try and make the recreational vehicle curve along a winding road. Anti-sway bars keep the vehicle from moving around in curves and prevent it from sliding. 

These bars give RVs more maneuverability, especially when passing other vehicles. The structure of the recreational vehicle will be more stable if there is no sway. This will also prevent unnecessary wear. The RV's structure may be compromised by constant sway, which can lead to leaks.


There are many types of anti-sway bars available. The type that you need will depend on your recreational vehicle, including whether it is a fifth-wheel trailer, pull trailer, or motorhome. Dual-cam sway control systems are suitable for large pull trailers.

These bars attach to the trailer's A-frame and swing bars, just beside the hitch. The trailer's cams hook on one side and prevent it from swaying before it starts. To allow the trailer to turn, the cams open to let it move but prevent excessive swaying. Attached anti-sway bars can be used on smaller tongue trailer hitches.


The weight distribution hitch is equipped with anti-sway bars. These bars are used to stabilize the trailer. These bars prevent trailer sway by shifting the trailer's weight to its rear axle and the trailer's rear. According to eTrailer, if the trailer's weight exceeds 50 percent of that of the pulling vehicle, it should have an automatic weight distribution hitch. The anti-sway bars on the hitch have a spring system that distributes the weight and reduces swaying.
