You load up for a weekend off the grid, knowing the weight will shift on rough trails. Instead of bracing for every dip, you drive with steady control and a smoother feel that lets you focus on the road ahead.
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 2,800 lbs of support at 50% compression so your truck stays more level and controlled.
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.
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.
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.
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.
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.

Hi everyone. Steve here with etrailer. Today we're taking a look at the Super Springs Solo Custom Helper Springs for the rear suspension. Now folks, these are a simple upgrade designed to improve load support, stability, and overall ride quality. And unlike traditional airbag systems, these are completely maintenance free. There's no airlines, no compressors, and nothing to adjust.
You just simply install 'em once and they're always working for you. Now, these are made of a microcellular urethane material, which gives you a progressive spring rate of 2,800 pounds at 50% compression. What's that mean Well, they're gonna stay soft when they're unloaded for comfort, but firm up as the weight increases to provide extra support you need during those times that you're using those heavier loads. That also is gonna mean less rear swag in the rear end, reduce sway, better wall control, especially when you're hauling gear, towing or carrying uneven load. So maybe you have a camper shell in the back of the vehicle or something like that.
This could be a great option for those kind of things as well. And these basically are an upgrade to your factory bump stops. They engage when needed. Again, that's gonna work. That's when they're gonna work, and they're gonna smooth out those harsh impacts.
Installation's pretty straightforward, excuse me. Once they're in place, they work automatically. There's no tuning, no monitor. And these basically replace your factory bounce stop. You get to include a hardware here with some thread lock, thread lock it looks like there in the blue.
And again, folks, these are a nice option for you. The Sumo Springs Solo Custom Helper Springs for the rear axle. I'm Steve with etrailer. Thanks for watching and as always, stay safe while you're towing.

Glad to hear the install wasn't too bad, Michael! Definitely let us know how the ride is once you take it out for a drive! What are you using your Van for? The tires look pretty beefy.

That is the beauty of SumoSprings! Super easy to install and once they're on you can forget they're there! Are you planning on towing something with your Jeep that you want extra support for?

The springs are working exactly as expect. I have need up to the mountains numerous times and to Monerary to the Sea Otter bike fest. They have reduced the body roll and helped keep the truck stable on the mountain roads or when loaded down for camping. Im very pleased I added these Sumo Springs to my Tacoma.

Glad to hear they are helping, Cory! If you are feeling them going over speed bumps, I think taking one of the spacers out is a good idea. Especially if that is happening when you are unloaded. Speaking of which, what are you towing?

One of my favorite things to recommend Kevin, the feedback is always so great on what a difference they make! What are you mainly towing that needed the extra support?
