SuperSprings diagram of roller and shackle system for extra leaf spring

These additional leaf springs add support and sway control to your existing OEM suspension. Just bolt on SuperSprings over your existing factory springs, and they automatically work when you need them. As the factory spring flexes, a roller at each end of the beefy helper spring reacts to engage the helper spring and to provide extra support. The springs help to better distribute cargo weight throughout your existing suspension, channeling that weight to the points on the frame that are designed to support heavy loads.


SuperSprings leaf spring installed on a vehicle

Placing these leaf springs above your factory springs helps to keep your OEM springs from twisting, so the SuperSprings act like a sway bar, reducing the body roll that makes driving more difficult and dangerous. With these helper springs, driving is safer and easier when it's windy, when your vehicle is rocked by a passing semi, and when you are cornering. The springs help to reduce sway by up to 30 percent. SuperSprings also allow more wheel travel in the rear suspension when they are under load, so they maintain traction and ride comfort better than rubber or polyurethane bumpers. That means they're great for drivers who frequently tow.


Truck before SuperSpringsTruck after SuperSprings

You can also customize the level of support provided by SuperSprings. For most models, the shackles that attach the helper leaf springs to your existing leaf springs have several installation options:

  • For greater support and ride height when your suspension is under a constant load or if you have an older automobile with some spring fatigue, install the helper springs using the upper bolt holes
  • To maintain the factory ride and reduce the effect on your ride height, install using the lower bolt holes
  • To balance support, height, and ride comfort, install using the upper hole on one end and the lower hole on the other

SuperSprings are a maintenance-free, low-cost alternative to air spring systems, which require constant monitoring and air pressure adjustment. These helper leaf springs respond automatically to the load you carry, so there is no crawling under your truck to adjust them. You'll also reduce wear and tear on your suspension, brakes, and tires, which saves you money. The bolt-on installation means that they are easy to fit - no drilling required.

  • Will The SuperSpringsSuspension Stabilizer SSA11 Fit A 2023 Ram Promaster 3500 Thor Motorhome?
    Hello William, thanks for reaching out. I double checked with my contact at SuperSprings and it looks like their site is correct in this case. The # SSA11 is a fit for the 2023 Ram Promaster 3500. It looks like our site was not updated to show the 2023 model, but I confirmed with SuperSprings that # SSA11 is the correct fit. As long as your motorhome is 4x2 and not 4x4 you will be good. If it is a 4x4 I am not able to confirm fitment.

  • How To Raise Generator Carrier on the Back Of a Winnebago Travato
    I do have an option for you but none of the suspension enhancements we have for your 2019 Winnebago Travato 59K on a Ram ProMaster 3500 Chassis will lift the motorhome from stock height. The SuperSprings Custom Suspension Stabilizer and Sway Control Kit part # SSA11 which is what I recommend will prevent the motorhome from sagging therefore increasing clearance but again nothing we offer will raise the rear of the motorhome from stock. If you are carrying the generator on a hitch mounted...

  • Will the SuperSprings Custom Suspension Stabilizer Help Bottoming Out On 2016 Pleasure Way Lexor TS
    The SuperSprings Custom Suspension Stabilizer and Sway Control Kit part # SSA11 is an excellent option for a 2016 Pleasure Way Lexor TS on a Ram ProMaster 3500 Chassis. It will do a great job of helping to prevent rear end sag thereby increasing ground clearance. Unlike the SumoSprings Solo Custom Helper Springs part # SSR-313-47, they will engage right away so this should then do a much better job of making sure you have as much ground clearance as possible. In regards to comparing the...

  • Rear Suspension Enhancement Product for Class C Motorhome to Decrease Sway and Increase Ride Height
    Assuming that your RV doesn't already have one, an anti-sway bar like # RM-1129-143 will keep your rear axle tied perpendicular to the frame which will be the most effective way to prevent the front end from getting squirrely on you. However, this option wouldn't affect your ride height. If you already have the OEM anti-sway bar, the addition of SuperSrings # SSA11 will offer pretty effective sway resistance, but would also raise your ride height by about an inch and would also help reduce...

  • Rear Helper Springs for a 2016 Ford Transit T250 Cutaway with KUV Utility Body
    The chassis on your 2016 Ford Transit T250 cutaway is the same as the cargo van models so you can use SuperSprings # SSA11. But what I recommend that will work just as well and that costs less is the SumoSprings # SSR-121-54. They will help keep the van level, absorb road shock, and reduce sway or body roll.

  • Availability of Anti-Sway Bar for 2022 Ram ProMaster 3500 Cargo Van
    Hey Chris (nice name), unfortunately the rumors you have heard are true. The Roadmaster Rear Anti-Sway Bar # RM52GR is only designed to fit the standard passenger chassis and isn't going to line up to the frame on your cargo van Promaster 3500. I know this isn't what you were hoping to hear. Can you tell me a bit about why you're needing the stabilizer? I only ask because depending on the type of ride you're getting now, there might be some other options that will help like the SumoSprings...
