What Are the Best RV Suspension Upgrades for Your Vehicle?

Mainline Truck Team • October 26, 2022

It's an unfortunate reality of RV sales that many RVs are sold with suspension systems that are barely adequate, at best. This can mean your RV could experience:

  • A very rough ride when driven off of well-maintained paved roads. 
  • Excessive sway
  • Porpoising
  • Excessive body roll when cornering


All of these symptoms can make driving a RV pretty nerve racking.  Let’s face it, your journey to your destination should be part of the fun.  Who wants to finally arrive at their destination all stressed out and fatigued.  This is a big part of the reason so many RV enthusiasts decide to purchase RV suspension upgrades

What's going to be the best Class A RV suspension upgrade for you?  There are many options on the market, and they each have their pros and cons.  Today we’d like to share our experience on what RV Suspension Upgrades will have the biggest impact on improving the way your RV handles and making your drive as relaxed and stress free as possible. 

Looking At the Four Best Options in Class A RV Suspension Upgrades


1. Install Sumo Springs

 

There are a lot of advantages in installing Sumo Springs:

  • Added Stability and weight control
  • Improved Driver Control and Comfort
  • Improved Sway Stability
  • They will never leak

 

Sumo Springs offer a progressive spring rate design meaning they become stiffer as you add more weight to inside your RV compared to a normal spring.  They are designed to give you a comfortable ride when going over those small bumps in the road. But, they become firmer than the O.E.M. spring when you drive over those large bumps in the road.  This provides a more stable and comfortable ride. 

 

Installing Sumo Spring kits enables both added stability and weight control. Sumo Springs can compress to 80% and stretch to 50% of its height with full memory rebound.  Their microcellular urethane springs are secured top and bottom with steel mounting brackets and hardware. 

 

Sumo Springs are also designed to provide up to 30% less sway and unlike airbags, they will never leak.


2. Install Safety-Plus Steering Stabilizer

 

Safety-Plus Steering Stabilizers are a positive centering, mechanically assisted steering control is unit that’s engineered to maintain straight-ahead steering. Safety-Plus Steering Stabilizers are designed to eliminate road wander, reduce the effect of cross winds and road ruts, and even maintain steer ahead when encountering blow outs.


3.  Install Front and Rear Koni Shocks.


Koni Shocks automatically adjust to various road surfaces. Koni Shocks minimize harsh ride and improve handling.  With a Koni Shocks
RV suspension upgrade, your RV will have reduced body roll.  These shock absorbers will also help to eliminate porpoising. 

 

Koni Shocks are adjustable so they can be tuned specifically for your RV insuring you get not only the most stable ride, but the most comfortable ride in all driving conditions.

4. Install SuperSteer rear Trac Bars and Sway Bars

Trac bars control side to side movement.  Rear axle Trac Bars prevent "Tail-Wag", greatly improving stability in turns and uneven grades. SuperSteer Trac Bars help to eliminate rear axle side to side play providing more predictable handling and more detailed steering.


Sway Bars or correctly called Anti-Sway Bars are another great way to upgrade your RV’s Suspension.  Sway bars connect the RV’s frame to the axle, increasing stability.  When it comes to sway bars, thicker is better, meaning more stability. Premium Sways Bars can make your RV drive more like a smaller vehicle that has less sway than a larger RV. 

Most importantly Premium Trac Bars and Sway Bars will greatly reduce drive fatigue.

This improves stability, steering control, and overall ride comfort.. You can emphasize this text with bullets, italics or bold, and add links.

  • How much do RV suspension upgrades cost?

    Costs vary based on what your RV needs, since different components may require replacement or improvement. Mainline Truck recommends beginning with a Road Performance Assessment to determine the exact upgrades needed and their cost.

  • Can a suspension upgrade help reduce driver fatigue in a Class A motorhome?

    Yes. Better suspension reduces swaying, bouncing, and constant steering corrections, creating a smoother, more controlled ride. This makes long trips more comfortable and less tiring for the driver.

  • How do I determine the best suspension upgrade based on my vehicle's make and model?

    The best way is to start with a Road Performance Assessment. This identifies the specific handling issues on your RV, and a technician can then recommend the most effective upgrades based on your coach’s model, chassis condition, and driving needs.

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!
