Reduce Sway and Improve Handling for Your RV with Track Bars and Sway Bars

WSI ALM • March 25, 2024

Motorhomes and RVs can be prone to swaying and handling issues when driving, especially in windy conditions or when making turns. This swaying motion can make driving stressful and reduce control. To help combat sway, motorhomes use two types of stabilizer bars - track bars and sway bars. Let’s take a look at how both options work to stabilize a motorhome and discuss the motorhome sway control strategies.

 

Track Bars vs. Sway Bars for Motorhomes

 

Track bars (also called panhard bars) and sway bars (also called anti-roll bars) serve similar purposes but work in different ways.

 

Track bars are designed to keep the rear axle centered under the vehicle. Without a track bar, the axle can shift from side to side, causing handling issues on turns. Track bars connect the axle to the frame to prevent this shift.

 

Sway bars help reduce body roll or leaning during turns and abrupt maneuvers. They connect the left and right sides of the suspension system. As one side compresses, the sway bar transfers force to the other side to keep the vehicle level. This improves stability.

 

How Track Bars Function

 

Track bars connect the rear axle housing to the motorhome frame on one side. This provides a lateral connection that keeps the axle centered under the vehicle as it moves.

 

The track bar needs to be parallel to the ground and at a precise length. If it is too short or angled, it can actually induce sway. Extended travel track bars with adjustable arms allow the length and angles to be tuned precisely based on the motorhome’s weight distribution and geometry.

 

High-quality track bars use spherical ball joints instead of cheaper bushings. This allows free rotation in all directions to prevent binding. Heavy-duty steel construction and greasable joints also improve durability for heavy motorhomes.

 

Adjustable track bars allow easy re-centering of the axle as needed, such as after adding accessories that change weight distribution. Once set up properly, the driver will feel much more stable tracking in turns without the rear end feeling loose.

 

How Sway Bars Improve Motorhome Sway Control

 

Sway bars (anti-roll bars) connect the left and right sides of the suspension. As the motorhome leans or rolls from cornering forces, the sway bar transfers force from the compressed side to the outside to keep the chassis more level.

 

This reduces body lean, keeping the tires better planted for more control. Less body roll also means less swaying from side to side.

 

Will RV Sway Bars Make a Noticeable Difference?

 

Adding track bars and sway bars to a motorhome can make a dramatic improvement in stability and ease of driving. Most owners report reduced swaying on the highway and when passing large vehicles. Turning feels far more controlled without the sensation of the rear end feeling disconnected from the front.

 

Overall, the motorhome feels much more stable and planted on the road. Driver fatigue is reduced on long trips. For larger Class A motorhomes especially, track and sway bars are recommended upgrades to improve safety and handling.

 

The difference is most noticeable at highway speeds and when making turns. On straight roads, the improvements may be subtler. However, the increased resistance to sway and lean means the motorhome will remain well-controlled when reacting to sudden maneuvers or wind gusts at any speed.

 

Many owners wish they had upgraded to these anti-sway bars sooner for the transformative effect on drivability and enjoyment of their RVing experience.

 

 

How Track Bars and Sway Bars Work

 

Track bars and sway bars operate in tandem to improve motorhome stability. The track bar attaches to the frame and rear axle housing laterally. This keeps the axle centered as the motorhome moves to prevent shifting. Sway bars connect the left and right suspension and transfer forces between sides. As the body rolls, the sway bar levels it out for flatter cornering.

 

More Control When Driving

 

With proper track bars and sway bars, motorhome drivers will feel far more in control behind the wheel. Turning and changing lanes induces less body roll and swaying. The motorhome tracks straighter on highways, even in gusting winds. Drivers can course correct with confidence knowing the rear won't slide out. Overall, the motorhome feels more planted and connected to the road.

 

Improved Ride Comfort

 

Excessive swaying not only reduces control but also creates discomfort for passengers. By counteracting body roll, sway bars provide a smoother ride over bumps and dips. Track bars prevent tail wagging that can throw off balance. Upgrades active shocks further isolate the cabin from bumps for maximum comfort.

 

Less Body Sway

 

Body sway can make passengers queasy as the motorhome tilts side to side through turns. Stronger sway bars transfer forces laterally to significantly reduce this sensation. Passengers will experience less sideways tilting, keeping their perspective level. This makes long trips more comfortable and enjoyable.

 

More Road Stability and Confidence in Difficult or Tight Areas

 

Between track bars and sway bars, motorhomes gain tremendous improvements in general road stability. Drivers will feel more confident passing large vehicles on highways and navigating tight mountain switchbacks. Windy conditions that used to push the motorhome around have less effect. Overall, the motorhome becomes much more stable and drivable in difficult situations.

Safe stopping is as vital as engine power when towing a heavy load. Many truck owners overlook trailer brakes until an issue arises. At Mainline RV & Truck Service , we handle various towing setups, primarily electric and surge brakes. Both systems stop a trailer safely, but they operate differently and require separate trailer maintenance approaches. Understanding these differences is essential for road safety. We offer an expert comparison, including specific maintenance needs. Understanding the Fundamental Differences Before discussing what keeps them running smoothly, we should look at how the two systems operate. Electric brakes get their power from an electrical signal sent from the tow vehicle. Pressing the truck’s brake pedal tells the brake controller to send electricity to powerful electromagnets inside the trailer’s drum brakes. These magnets engage an armature plate, which then forces the brake shoes out against the inside of the drum. Surge brakes use hydraulics and work on their own, independent of the truck’s electrical system. Their operation is based on inertia. When the truck begins to slow down, the trailer pushes forward into the hitch. That physical pressure compresses a master cylinder built into the trailer coupler, which then pumps hydraulic fluid to the brake cylinders or calipers. Because one system is powered by electricity and the other by fluid pressure, their weak points and overall maintenance needs are very different. Electric Brakes: Fine-Tuning and Electrical Integrity Electric brakes are standard equipment for nearly all travel trailers and large, heavy-duty flatbed trailers. Since they depend on a good connection between the truck and the trailer, maintenance starts right at the hitch and extends all the way to the brake shoes. Adjusting the "Gain" on Your Brake Controller A key part of operating electric brakes is a setting that you control from inside the truck’s cab, not on the trailer itself. The “Gain” value on your brake controller sets the amount of electrical power sent to the trailer brakes. If the gain is set too low, the truck does all the braking work, which leads to your truck’s rotors getting too hot and your stopping distance increasing. Setting the gain too high means the trailer brakes will lock up easily. Routine truck trailer repair and safety checks involve resetting the gain any time the weight of your load changes significantly. A carefully adjusted gain ensures the truck and trailer brake together, preventing unnecessary stress on either vehicle. Troubleshooting "Grabby" or Locking Brakes A common complaint is that the trailer brakes feel “grabby,” meaning they engage too suddenly or violently with only a little pedal pressure. Often, something is causing a maintenance issue. Common reasons include: Corrosion on the electromagnets: If the trailer has been sitting unused, rust can form and cause the magnets to stick when engaged. Incorrect Gain settings: As mentioned earlier, improper calibration is a frequent culprit. Grease on the shoes: A failed wheel seal can let grease leak onto the brake components, leading to unpredictable braking action. During a professional trailer repair inspection, mechanics remove the drums to check that the magnets are wearing evenly and confirm that no oil or debris is contaminating the friction surfaces. Surge Brakes: Hydraulic Health and Fluid Management Surge brakes are most frequently seen on boat trailers (where electrical parts and water do not mix well) and on rental trailers (because the tow vehicle does not need a specialized controller). Checking Fluid Levels for Surge Couplers Surge brakes primarily fail due to low hydraulic fluid. As the master cylinder in the trailer's tongue or coupler is exposed to constant movement, seals wear, and moisture can enter the system. Routine maintenance requires checking the master cylinder reservoir fluid level; dark or cloudy fluid indicates moisture contamination, necessitating a full flush and replacement. Without sufficient, clean fluid, the surge coupler cannot generate the force required to activate the brakes, leaving the trailer brakeless. Inspecting the Moving Parts of the Coupler Since surge brakes work by the physical “sliding” movement of the coupler mechanism, that sliding part must be kept lubricated and clean. If the coupler rusts or jams up, the brakes might stay applied even when you are driving, or they may completely fail to engage when you slow down. The Common Ground: Shoe Adjustment and Wear The way the brake shoes are moved might be different, electricity for one, hydraulics for the other, but the shoes themselves need manual upkeep in both systems. Shoe Adjustment Intervals for Heavy-Duty Trailer Repair While some newer trailers feature self-adjusting brakes, many heavy-duty models still need manual adjustment. As the friction material on the brake shoes wears away, the space between the shoe and the drum increases. The result is a noticeable delay in braking response. For dependable safety, we advise having your brake shoes inspected and adjusted every 3,000 to 5,000 miles. During a trailer maintenance appointment, a technician uses a “star wheel” adjuster to move the shoes closer to the drum. This ensures that the trailer brakes immediately when you press the pedal. Which System is More Maintenance-Intensive? Surge brakes demand hands-on maintenance (checking fluid/grease). Electric brakes risk less obvious electrical failures (wiring, fuses, ground). For heavy loads, electric brakes offer a manual override for sway correction, but require electrical knowledge for troubleshooting. Surge brakes are simpler for the driver but need constant hydraulic system vigilance to prevent failure. Summary Checklist for Trailer Safety Keep your trailer operating at its best by following these simple guidelines: Annual Inspections: Have a certified professional examine your brakes and wheel bearings at least once a year, regardless of how many miles you have driven. Test Before You Tow: Always perform a quick “tug test” to confirm the brakes are working before you get out on the road. Watch for Corrosion: Check the 7-way electrical plug (for electric brakes) or your brake fluid lines (for surge brakes) for any signs of rust or damage. Listen: Squeaking, grinding, or clicking sounds are the most immediate indicators that truck trailer repair is necessary. Contact Mainline RV & Truck Service for Trailer Repair & More!
