Rear Suspension Support

SumoSprings helper springs are great for RVs or motor homes. Heavy rear loads can cause sag as your factory suspension compresses under the weight of the load. This means that the rear axle is trying to support not only the extra load but also the motor home's weight. And because there is less weight on your front axle, your front tires make less contact with the road, which causes problems with traction, steering, and braking. SumoSprings upgrade your vehicle's factory suspension to level your vehicle, improve driving performance, and keep your ride comfortable.


SumoSprings diagram of installation above existing vehicle spring

Each spring in this kit is bolted to two mounting brackets. One bracket is attached to the frame of your vehicle, and the other bracket is attached to the axle, typically above your existing factory leaf spring. Because each helper spring is in full contact at the top and bottom of the suspension's travel, the expanding and contracting action of the SumoSprings enhances your ride under all conditions, not just when it's loaded. And the closed-cell urethane springs act like a shock absorber to dampen road vibration.


SumoSprings compressing under load

SumoSprings provide progressive load control - the more you load them, the stiffer they become. With a lighter load, the springs will compress easily for soft engagement and a less bumpy ride. The springs can also compress by as much as 80 percent to support a heavy rear load and to help your factory suspension bear up under the load. This evens out the weight, which levels your vehicle and ensures that your front tires are making better contact with the road. A level ride means that you have improved driving control, ensures safe headlight aim, and helps to minimize sway. The springs also support your factory suspension, which helps prevent sagging and reduces bottoming out.


The springs work independently from one another to support each side of your vehicle. This action helps to reduce body roll when you make a sharp turn. This also helps compensate for an off-center load.


SumoSprings expanding to allow play in the suspension

These springs extend in height by as much as 50 percent to allow more movement in your suspension when you're traveling unloaded, making your ride smoother and more comfortable.


Durable, Custom-Fit Springs

These microcellular urethane springs are tough. They resist abrasion, oil, salt, and UV rays that can more quickly wear out other springs, and they perform well in temperatures ranging from -25 F to 200 F (-33 C to 93 C).


SumoSprings expand and compress vertically with minimum expansion to the sides, so they won't be damaged by nearby mechanical parts and they fit safely into tighter spots. And unlike air springs, SumoSprings require no maintenance or adjustment.


This kit comes with custom-fit brackets that are designed to easily bolt onto your vehicle.

  • Recommended Driving Enhancements for 2017 Thor Hurricane 29M Class A on Ford F53 Chassis
    Your 2017 Thor Hurricane 29M is built on a Ford F53 chassis. For the Sumosprings, I recommend the SumoSprings Rebel Custom Helper Springs - 2 Piece - Front Axle # SSF-170-40-2 and the SumoSprings Maxim Custom Helper Springs - Rear Axle # SSR-187-40-1.

  • Recommended Suspension Enhancement For A 2016 Newstar BayStar 3518 Class A Motorhome
    Hey Tony, We unfortunately don't offer any steering stabilizers under the Safety Plus brand but we do offer some from Roadmaster that will definitely improve your handling and ride quality. For the stabilizer you'll need the Roadmaster Exact Center Steering Stabilizer # RM42RR. For the anti-sway bars you'll need the Roadmaster Rear Anti-Sway Bar # RM-1139-149 (1-5/8" thick) and Roadmaster Front Anti-Sway Bar # RM-1139-148 (1-3/4" thick). Make sure you measure the diameter of your current...

  • SumoSprings Kit Recommendation for 2019 Thor ACE 30.2
    For your 2019 Thor ACE 30.2 I recommend the SumoSprings part # SSR-187-40-1 over other options as it will give you the better suspension support and improved handling you are looking for without creating harshness in the ride quality like the Timbren kit would. The matching front kit is the # SSF-170-40-2. I attached install videos for both of these kits for you to check out as well.

These springs are made for models ranging from 16,000 to 22,000 lbs. These springs will mount both on top and bottom but are not connected. They will absorb the road shock, but will also allow full axle movement so you will have the best steering ability and traction. For the rear, I recommend the SumoSprings Maxim Custom Helper Springs # SSR-187-40-1. These...

  • Choosing Between SumoSprings or Timbren for 2013 Fleetwood Storm 32BH
    Although either the # SSR-187-40-1 Sumo Spring or the Timbren # TFRF53A would be a great choice, the Timbren Aeon spring is actually rated higher at 8600 lbs, versus 2600 lbs for the Sumo Springs alternative. Neither of these options will come into play unless the factory suspension gets compressed. If ride quality is the more important consideration, the Sumo Springs option is what I'd recommend as they' give a more supple ride. If reducing roll in the corners is foremost in your mind,...

    The biggest difference between the two for your 2019 Thor ACE 30.2 motorhome, and the reason why I highly recommend the SumoSprings over the Timbren, is what each product is constructed from. The Timbrens are made from a strong, rigid rubber while the SumoSprings are made from microcellular urethane. This is important because it means the SumoSprings will compress more gently, while the Timbrens are known to give a much stiffer ride. The front axle and rear axle fits for your 2019 Thor...

    The jounce springs I recommend for your two wheel drive 2019 Ford F-53 chassis are from SumoSprings, the SumoSprings Rebel for the front axle and SumoSprings Maxim for the rear axle. The reason why the SumoSprings are the best is because they not only work to reduce sway, but also keep your vehicle level and give you a smoother ride. The SumoSprings can do this because they are made of a microcellular urethane which compresses. Each of the springs works independently which is what is going...

Unfortunately, for the rear axle the only comparable option is the Timbren Rear Suspension Enhancement System # TGMRC55.

When compressed, it will extend back to neutral, and when extended it will retract back to neutral. This reduces road fatigue by making it easier to steer. It helps with crosswinds, uneven pavement, rut tracking, road edging, or even a tire blowout so you can easily maintain control. For the rear Anti-Sway...

  • Will the SumoSprings Helper Springs Raise the Height on a 2016 FR3 with a Ford F-53 Chassis
    The SumoSprings Helper Springs typically don't raised the height of the vehicle they are installed on. They are designed to offer help when the vehicle is swaying or under a load in which case they basically just cause resistance. The reason I said that they typically do not raise the height is because if the suspension is in bad shape they have been known to help the suspension out and raise the vehicle a little.
