  • Ensures that SuperSprings operate silently when your vehicle isn't loaded
    • Maintains minimal preload tension in the installed SuperSprings for a quieter ride

SuperSprings diagram of factory springs set above and below 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. The kit includes 5-1/4 inch long U-bolts for applications where the spring pack measures greater than 2-3/4" high.


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.


Bolt the mounting brackets to the factory spring packs using the extended U-bolts, cross plates, washers and nuts included in the kit. When installed correctly, the Nylok self-locking nuts won't loosen. After you install the mounting brackets, tighten the U-bolt nuts while the rear of the vehicle is still off the ground. After the springs are installed, lower the vehicle to the ground and retighten the U-bolt nuts.

  • Recommended Leaf Spring Suspension Enhancement for Trailer
    The SuperSprings Mounting Kit for OEM Leaf Springs Above the Axle # MXKT is designed to be used with a SuperSpring Custom Suspension like the # SSA28 and allows you to mount the springs above the axles instead of below them with the rest of the leaf spring pack. These springs are designed for a truck and not a trailer, so it's really not going to be a solution that would work for you. If you can tell us more about your trailer, like the axle capacity and how many axles there are, we can...

  • Which Super Springs for 2019 GMC Sierra 2500 for Towing 5th Wheel Trailer with 1400-lbs Pin Weight
    Yes. The Sumo Springs Super Springs # SSA16MXKT are a great choice to help give you a bit of extra support when towing your 5th wheel. These aren't going to create any lift when the truck is unloaded and will only activate when the truck is under a load to help keep the ride height factory at all times, so they're a great solution for your 2019 GMC Sierra 2500. These springs will also help reduce sway and prevent sagging to improve the safety of your towing experience, as well. If vehicle...

  • SuperSprings Suspension Stabilizer for 2020 Ram 3500 Cab/Chassis Dually
    According to SuperSprings, the # SSA15MTKT kit isn't a fit for chassis/cab models, it'll only fit the pickup. For your chassis cab, you'll want to use # SSA23 along with the # MTKT (assuming that your leaf springs are mounted above the axle.) If your spring pack is thicker than 2-3/4 inches, you'd use # MXKT instead. The # SSA23 is compatible with DRW vehicles with or without top overload springs.

  • Troubleshooting Weight Distribution System Still Causing Vehicle Rear Suspension to Sag
    Your description of needing to jack up the rear of the vehicle to take the bars off leads me to believe that you're speaking of a weight distribution system. A correctly set up system will distribute a portion of the trailer tongue weight that bears down on the rear axle to the front axle, to level the right height between the front and rear axle. Beefing up the rear suspension can help, but it works much better for a load carried in the bed of the truck. For sag caused by a trailer tongue...

  • SuperSprings and SumoSprings on 2016 Chevrolet Silverado 2500HD
    Yes, you can use both the SuperSprings Custom Suspension Stabilizer # SSA13MXKT with a set of SumoSprings # SSR-203-47-2. These will not increase the weight capacity of your vehicle, they will improve your ride quality and reduce squat when hauling heavy loads. For the SuperSprings use this kit # MXKT to mount your SuperSprings leaf spring helper kit if your factory leaf springs are located above your axle and your spring pack is more than 2-3/4" thick.
