When you hitch up or load down the bed, these helper springs add up to 3,000 lbs of support at 50-percent compression to keep your ride level. They absorb bumps and shocks so your steering and braking stay confident even with a heavy trailer or bed load. With a level stance, your truck feels balanced and your headlights stay aimed where they should.
The two-piece Rebel setup connects at the top and bottom to provide unlimited suspension travel. When unloaded, the halves separate for full suspension movement and a smoother ride. As weight increases, the microcellular urethane springs compress progressively—soft at first for comfort with lighter cargo, firming up to as much as 80 percent compression to handle heavier loads without bottoming out.
Each spring works on its own side of the vehicle to help control sway and body roll. That independence helps compensate for uneven cargo or off-center trailer weight so you feel steady when cornering or hitting uneven pavement. The result is a more planted ride that keeps the truck from leaning or bouncing when the load shifts.
These closed-cell urethane springs don’t need air lines, tubing, or pressure checks. They expand and compress vertically with minimal side movement, resist oils, salts, and UV rays, and perform in temperatures from -25 F to 200 F. The custom brackets bolt on easily with included hardware, giving you a simple setup that just works every time you haul or tow.

Hey Steve. Thanks for the feedback. This Rebel kit is designed for vehicles carrying variable heavy loads, so some contact at unloaded ride height can be normal depending on the application. If this is a dually, keep in mind this particular kit is intended for commercial applications only, where earlier engagement helps support the heavier loads these trucks regularly carry. I’d still verify the brackets and spacers match the instructions, but the Sumos contacting before the factory overloads does not automatically indicate a problem with this setup.

Glad to hear it! I'm a big fan of SumoSprings because they're so easy to install and don't require any maintenance after. What kind of trailer are you hauling?

The springs work great. After a year in service, they are like new. We use this truck as a rental equipment delivery truck. We pull a 26ft gooseneck tilt deck trailer that is 16K rated. The ride is great and the springs handle the load nicely with no sag when loaded. We have added these springs to all 6 of our 1-ton delivery trucks.

These will not fix an already sagging suspension. These are designed to help support suspension but leaf springs need to be replaced they will not fix that much sag. I would recommend using some airbags, like part # F2703, in place of Sumo Springs. You will need a compressor, like part # F2097 for the airbags.
