800-lb Capacity. Install these helper leaf springs above your vehicle's rear factory leaf springs. They reduce sway and prevent sagging, which is perfect for towing or hauling heavy loads. Designed for OEM springs that sit above the axle.


Features:

  • Reinforce your vehicle's rear suspension with extra leaf springs that prevent sagging and reduce sway by up to 30 percent
    • Work like sway bars to stabilize your OEM springs and keep them from twisting
    • Compensate for windy conditions, wind turbulence from big rigs, and weight shifts while cornering
    • Lift your truck when you are carrying a heavy load and prevent bottoming out
  • Adjust automatically to your payload
    • Rollers on each end of the SuperSprings activate when the OEM springs flex under load
    • Rollers deactivate when OEM springs aren't under load
  • Customizable - the shackles attaching the SuperSprings provide several options for installation
    • Choose a setting that increases load support and ride height for constant heavy loads or to compensate for minor spring fatigue in an older automobile
    • Choose a setting that maintains the original factory ride conditions and minimizes effect on unloaded ride quality and height
    • Choose a medium setting that balances support, height and ride comfort
  • Install easily - bolt on above your existing factory springs with no drilling required
    • Because factory springs set above the axle, an additional mounting kit is included for installation
  • Require no maintenance - no tubing or air pressure to monitor or adjust like air springs
  • Extend the life of brakes, tires, and factory suspension
  • Made in the USA

  • Weight capacity: 800 lbs

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.

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 semitruck and when 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.


This suspension stabilizer kit is perfect for trucks towing fifth wheels, campers and gooseneck trailers.

An additional mounting kit is included for installation with factory springs that set above the axle.


For vehicles with factory leaf springs that set above the axle, this mounting kit ensures that SuperSprings operate silently when the vehicle isn't loaded. When factory springs set below the axle, the axle itself serves as a fulcrum for the helper leaf springs. However, for vehicles that have OEM springs that set above the axle, the 2-inch brackets in the mounting kit act as fulcrum points on the underside of the SuperSprings. Furthermore, the shackles at the ends of the helper springs hold them in place and pivot as the load is transferred to the SuperSprings. Because there is minimal preload tension in the installed SuperSprings, you get a quieter ride.

  • Recommended Mechanical Suspension Enhancement for 2018 Chevrolet Silverado 1500
    It sounds like your weight distribution system is working well and you just need some suspension support on your 2018 Chevy Silverado 1500. I don't recommend the leaf springs you referenced but rather the RoadActive Suspension Custom Leaf Spring Enhancement Kit - Heavy Duty # RAS54FR. This is a mechanical system like the leaf spring system you referenced but this system allows you to fine tune adjust your ride and once set to your desired feel leave it alone as you will only engage the...

  • Recommended Suspension Enhancement System for 2016 Nissan Frontier
    Both the SuperSprings Suspension Stabilizer # SSA1MTKT and the Firestone Ride-Rite Air Helper Springs # F2558 referenced in your question are confirmed to fit your 2016 Nissan Frontier. Between the two systems, I recommend going with the Firestone Ride-Rite Air Helper Springs # F2558. These will provide a higher capacity to handle the additional tongue weight of both your topper and camper, and also allow for adjustability with the air bags. This simply means that you will have much greater...

  • Will Both Sets of Bump Stops Need Trimming When Installing SuperSprings on 2006 Nissan Frontier
    I consulted the installation instructions for the Sumo SuperSprings # SSA1MTKT, and on your 2006 Nissan Frontier the lower bump stops are the only set that will need to be trimmed. There are no instructions of altering or replacing any upper bump stop when installing the spring to this vehicle.

  • SuperSprings Slide Forward on Leaf Spring Pack
    It sounds like the hold down clamp (see photo) has loosened which has then allowed the SuperSprings Suspension Stabilizer and Sway Control Kit part # SSA1MTKT to shift forward on your 2015 Nissan Frontier. In order to fix this you will want to loosen the two nuts at the bottom of the clamp and then shift the spring back into position while tightening the nuts back down. This should keep the spring in place but if it does not please let me know and I would be happy to let you know what options...

  • Will SuperSprings Eliminate Axle Wrap On 2013 Nissan Frontier
    With that few miles you have on your 2013 Nissan Frontier, it sounds like the suspension is the problem and I recommend you take it back to the dealer and have them check the entire system out before investing in suspension enhancements. I spoke with my contact at SuperSprings about the axle wrap. They told me that installing SuperSprings like part # SSA1MTKT, will help a bit with the axle wrap, but will not eliminate it altogether. According to the installation instructions, the bump...

  • Will the SuperSprings Suspension Stabilizer For a 2014 Nissan Frontier Work with Rough Country Lift
    The SuperSprings Suspension Stabilizer and Sway Control Kit part # SSA1MTKT which is a fit for a 2014 Nissan Frontier is designed for the factory suspension. That said, I don't see how extended shackles would create any issues so you should be good to go. I looked up the Rough Country Kit for you as well to make sure there were no other components that could interfere.

  • Will SuperSprings Suspension Stabilizer # SSA1MTKT Provide Lift to 2007 Nissan Frontier
    The SuperSprings Custom Suspension Stabilizer # SSA1MTKT are not intended to increase the height of your 2007 Nissan Frontier. The stabilizer is meant to provide more support for your vehicle when carrying heavy loads in the cargo area or towing a trailer as well as protect your existing suspension and your brakes and tires. This product will maintain the stock height of your vehicle and the only way it should raise the height is if your vehicle is already sagging due to poor support due...

  • Suspension Enhancement Recommendation for a 2015 Ford F-250 for Fifth Wheel Towing
    For suspension enhancement for your 2015 Ford F-250 that is compatible with the fifth wheel hitch you have installed in the bed of your truck you would want the part # F2550 for if you have a gasoline engine or part # F2597 for if you have a diesel engine. Air bags do require a tiny bit of maintenance as you have to keep at least 5 psi in the bags, but the ease of adjustability with them make them a great choice. I attached install videos for both products mentioned. For a compressor...

  • Which SuperSpring Suspension Stabilizer for 2015 Chevy Silverado 1500 Towing 7000 lb 5th Wheel
    For your 2015 Silverado 1500 4x4, I'd recommend the Super Springs, part # SSA5MTKT. The springs come into play as load (the pin weight of your fifth wheel) is added to the rear suspension. There's also some adjustability available, so you can dial in the amount of support and sway control needed. You'll need to measure the thickness of your existing spring pack to ensure the U-bolts included with the kit will be long enough. Measure the thickness of the leaf spring where it sits directly...

  • Recommended Suspension Stabilizer and Sway Control Kit For 2012 Nissan Frontier
    The kit I recommend for your 2012 Frontier is part # SSA1MTKT. These sit above your OEM leaf springs and help prevent sagging like you said you have and also help with sway control. This system uses rollers that automatically adjust when the truck is placed under a load. You can also choose a customized setting that matches what you need from the springs. The weight capacity of the springs is 800-lbs.
