When towing a heavy trailer or hauling gear in the bed, the rear end can sag and throw off handling. These SumoSprings Rebel helper springs add up to 3,000 lbs of support at 50-percent compression to help your suspension carry the weight. They keep your ride level so your steering, braking, and headlight aim stay consistent. By supporting the rear axle when loaded, they also help minimize squat and bottoming out.
A rough ride when empty isn’t something anyone wants. The 2-piece design of these SumoSprings connects at the top and bottom under load but separates when unloaded for full suspension travel. That means you still get a smooth, comfortable ride on rough roads or when running light, with plenty of movement to absorb bumps instead of bouncing over them.
Whether you’re carrying a few tools or a full load, these microcellular urethane springs adjust automatically. Lighter loads compress softly for an easy ride, while heavier loads compress by as much as 80 percent to provide strong support. That progressive load control keeps things balanced no matter how much weight you add.
When side winds or uneven loads try to push you around, each SumoSpring works on its own. The independent spring action evens out off-center weight and helps reduce body roll through turns. The result is a planted feel on highways and mountain roads alike.
These microcellular urethane springs handle temperatures from -25 F to 200 F and resist oils, road salts, and UV rays. They compress vertically with minimal side expansion, protecting them from contact with nearby parts. With no air lines or pressure adjustments needed, installation is a simple bolt-on job with hardware included—maintenance-free once installed.

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.

Product is excellent. The springs really reduced the squat I used to have in my truck when I hooked up my fifth wheel camper. Actual reduction in squat was around a 2 inch change. This also keeps the nose of the truck from rising in response to the rear sag I used to have, which makes the overall handling of the total rig a bit better as well. Also, the ride, while connected, is noticeably smoother and feels more stable while driving in stout crosswinds, which we frequently enjoy, here in Oklahoma.

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.
