SHOP FOR SUMOSPRINGS

SumoSprings are not made from rubber. They are a progressive spring with a very soft initial engagement. That means that as more weight added, the harder they get and more they push back, providing support and control when you need it without affecting the factory ride when unloaded.
These are a suspension enhancement built to create a better journey. Manufactured from our micro-cellular polyurethane, they are designed to reduce rear-end sag, decrease vibration, stabilize sway, and soften harsh rebounds.

Two applications.
Enough to cover just about every trailer out there.

SPRING-OVER AXLE CONFIGURATION
Trailer SumoSprings are manufactured from our micro-cellular polyurethane - the same airbag alternative in the rest of our SumoSprings lineup. These are specifically designed to remove sway, hop, & vibration.
This zero-maintenance airbag alternative increases overall driver control and ride comfort when towing.

If you've got a leaf-spring trailer, you either have the axle tube under the leaf, or above it. We have an option for both. Once you know your axle configuration, you'll pick your SumoSprings density.
If your towable has axles with a weight rating of 3-5,000lbs, you'll need the blue (-40) Trailer SumoSpring. Anything 5,000lbs or greater, you'll want to go with the black (-47) SumoSprings option.

You've got coils. We've got options.
Coil SumoSprings are made from the same material as our other SumoSprings products – a micro-cellular polyurethane that decreases vibration, stabilizes sway, and tightens up your existing factory coils. This upgrade adds up to 30% additional capacity to your coils, creating a cushion effect and stopping unwanted dip and roll.

How to find your Coil SumoSpring:
Measure the gap between in the middle of the coil. Enter the measurements below for the right fit. Take the measurement with the vehicle as it sits. You do not need to raise it. Ensure that each side of the vehicle is within 1/4" (0.25") measurement of the other.
