Features to know about

Stay Level When the Bed Gets Heavy: Progressive Load Support


Installed spring when it is not compressed Installed spring when it is compressed

When you load up gear for a trip or haul tools for the job, the rear end can start to squat and throw off your handling. These springs compress as weight comes on, adding up to 2,300 lbs of support at 50% compression so your truck stays more level and controlled.

Take the Edge Off Rough Roads: Micro-Cellular Cushioning

Rough trails and uneven pavement can make the back end feel harsh and bouncy. The closed-cell polyurethane design acts like a cushion, soaking up bumps and softening rebounds so the ride feels more settled instead of choppy.

Cut Down on Sway in Corners and Crosswinds: Progressive Resistance

You know that uneasy feeling when the rear starts to lean in a turn or shift in the wind. These springs firm up as they compress, helping reduce sway and body roll so the truck feels more planted when things get unpredictable.

Forget Constant Adjustments: Maintenance-Free Design

Air systems can be a hassle with lines, leaks, and pressure checks. This setup is a one-piece solution with no maintenance needed. Once it is in, you can just drive and not think about it again.

Simple Upgrade from Factory Stops: One-Piece Replacement

Instead of stacking add-ons, this replaces your factory bump stops directly. It is a clean, straightforward upgrade that works quietly in the background without changing how you use your truck day to day.

Smooth Out Loaded and Unloaded Driving: Consistent Rear Support

Some setups only help when fully loaded, but these stay engaged lightly even when you are not hauling. That means less rear-end bounce on daily drives and more control whether the bed is empty or packed.

Video Transcript for Review of SuperSprings Intl Vehicle Suspension - Towing/Load Leveling - SS27UJ

Hi everyone. Steven here with etrailer. Today we're taking a look at the SumoSprings solo custom helper springs for the rear axle. Now these are a custom fit application for a 07 to 26 Jeep Wrangler, and these are going to do a great job at upgrading your factory bump stops in the rear of that Jeep Wrangler. So these will replace those factory bump stops and you get all the included brackets and nuts and bolts and everything included that you may need, spacers and whatnot. And these are made from a microcellular urethane material, which gives them a progressive spring application, meaning when they are no load on, they're gonna stay soft and look like this, and when they get pressed down with weight, that's when they're gonna be progressive and give you the support you needed based on the weight that's pushing down on 'em.

And that's gonna translate into less rear end swag, sway, and give you overall control when you're hauling gear and towing. And the best thing about this to me is it's a maintenance free install, you install once, boom, you're done. You don't have airlines, compressors, things like that to worry about leaking or adjust or maintaining maintenance on those kind of things up underneath the vehicle. So this is a one piece design along with the spacers and everything there, but the main unit here is a one piece design. And SumoSprings have been around for ages.

You can look them up if you've never heard of 'em. They do a great job at this kind of stuff. And if you have any questions about this that I didn't cover, you can always reach out to us here as well. And if you don't wanna tackle the install, we got you covered as well. Check out our install locator link below and based on your zip code, we can get you in touch with trusted etrailer installation shops around the country.

I'm Steven. Thanks for watching.
