A heavy load up front can make the front end dip and throw off how your vehicle steers and brakes. These SumoSprings Solo helper springs add up to 1,400 lbs of support at 50-percent compression to keep things level and controlled. They help your factory suspension handle extra weight and absorb bumps so steering feels solid and headlights stay aimed where they should.
These springs are built with progressive load control, so they compress softly for small bumps and firm up as the weight increases. Light loads get a cushioned ride that feels smooth and steady, while heavier loads get up to 80 percent compression for strong support that keeps your suspension from bottoming out. The result is a more even ride no matter how much weight you’re carrying.
When uneven loads or sharp corners try to push you around, each spring works on its own to keep both sides balanced. That independent movement helps cut down body roll and sway so the vehicle stays planted through curves, crosswinds, or rough terrain. You’ll notice less rocking when pulling into driveways or stopping on uneven ground.
These durable microcellular urethane springs hold up through all kinds of conditions—resisting oils, road salts, and UV rays, while working in temperatures from -25 F to 200 F. They compress vertically with minimal side expansion, so they fit safely in tight spaces without getting chewed up by nearby components. And because they’re maintenance-free with no air lines or pressure to monitor, you just install them and go.
Adding front-end support doesn’t have to be complicated. These custom-fit helper springs bolt on with a simple, no-drill installation using basic tools. It’s a straightforward upgrade that’s easy to take on in your own garage or driveway without needing to run airlines or adjust pressures later.

Ellen: Hey everyone, I'm Ellen here at etrailer.com. Today we're taking a look at the SumoSprings solo custom helper springs. These are going to be for the front axle of the 1997 through 2006 Jeep TJ Wrangler. So this is going to help to support the front end of your Jeep and help you get a better ride out of it. A lot of times whenever you have a heavier load on the front end of your Jeep, maybe if you have a winch loaded up there, a little extra weight on the front end, it can cause some issues, so we're going to be able to support that. It's going to replace your existing jounce bumper.
So for the install process, you might have to remove the drag link arm, the coil, and the sway bar to get at that old jounce member, pull that out of place, twist this new guy in there, and then replace all your parts.So it's definitely something that you can do at home if you have some mechanical knowledge to get that done, it's pretty much just a matter of taking things apart and then popping this new guy back in, but there's no cutting or drilling required with these. Once they're in there, you don't really have to worry about any kind of maintenance, they're just going to be there to do their job. The nice thing about these is that they have a progressive load control. So basically as these compress, they get denser and they give you more support. So with lighter loads, they just compress easily and they're fairly soft and they give you that less bumpy ride.
As the load gets heavier on them, they are going to compress by as much as 80% for support. They also work independently of each other so you don't have to worry about any kind of off center loads. It's also going to reduce any kind of body roll whenever you're going around a sharp corner.It's made of a microcellular urethane, which has a good life as far as being able to resist any kind of oils, road salts, and UV rays. So it should last for a long time. Again, no maintenance required with these, no air lines to run into these that you have to then maintain, so pretty easy to maintain once they're in place.
They do have a temperature range from negative 25 degrees Fahrenheit up to 200 degrees Fahrenheit, so even if you're in the colder States, or out to the desert, you should be fine as far as use with these. They don't really expand out side to side too much, so there's very minimal lateral expansion as they compress. They stay pretty tight to this profile, so you don't have to worry about any kind of damage from contact with your wheel, or any other suspension components. So it shouldn't have any issues being in tight spaces.And again, no maintenance required, no drilling required. We do get two of our springs here.
The weight capacity for each of these at 50% compression is going to be 1400 pounds, or 1,400 pounds. Now the important thing to keep with that number, and that's for both of the springs at once, I think I said individually, but that's for both of the springs, but that 1400 pounds is not going to mean that you can have that much additional weight in your Jeep, that's just there to support that much weight. So you're not going to have any more of a payload from your Jeep, you never want to exceed your manufacturer's recommended weight ratings. It's just there to give you that extra support so that your ride is better, helps your other suspension components work correctly.Another thing to know with these is that if you have a aftermarket coil, these really are not designed to work with that, they're meant to work with your factory coil. So if you do have a modified coil on your Jeep, you might need to get a different set to work with your setup. It does come with a two year limited warranty, and these are made in the USA. That's going to do it for our look at the SumoSprings solo custom helper springs for the Jeep TJ..

30 Minutes for all 4?! That's got to be some kind of record, Dennis! Glad the process was nice and easy and I hope they serve you well. Let us know if you do end up needing to go to the heavier duty yellow option as well, we always like to get real life experiences from people. : ) Any more trips planned for the year?

That is awesome to hear! It must be such a relief to not have to put so much energy into controlling the wheel while driving now.

It was a great investment. It truly helped with the front end bouncing. I look forward to adding a set to the rear.

Appreciate you leaving a review Austin, It's always nice when a product exceeds expectations and these springs have been highly rated. Are you typically off road or do you plan on towing?
