Features to know about

Stay Level and Confident Off-Road: 1,400-lb Front Suspension Support

Heavy front-end gear or uneven terrain can make your ride nose down and throw off steering control. These SumoSprings Solo helper springs add up to 1,400 lbs of support at 50-percent compression to keep your suspension level and stable. They absorb bumps and shocks over rough ground so steering stays consistent and braking feels more controlled, even when carrying winches or aftermarket bumpers.

Smooth Out Rough Trails: Progressive Load Control That Adapts to Weight

Off-roading means dealing with everything from light gear to heavy loads, and these springs adjust to match. They compress easily at first for a soft, comfortable ride when you’re not carrying much, then compress by as much as 80 percent under heavier weight for solid support. The progressive load control helps smooth out harsh jolts so you can handle rocky or uneven terrain without the constant bounce and sway.

Tackle Bumps with Faster Activation: Taller Microcellular Urethane Springs

Standard bump stops can wait too long to engage when you hit a deep rut or rock ledge. These taller microcellular urethane springs engage sooner, absorbing big impacts before they upset your balance. The result is better traction and comfort when crawling or climbing, with less front-end dive and more predictable handling through obstacles.

No Maintenance, No Hassle: Bolt-On Installation with 1" Lift Spacers Included

Once they’re installed, you don’t have to think about them again. The high-density urethane material resists oils, road salts, and UV rays while working in temperatures from -25°F to 200°F. They mount above your existing springs using a no-drill bolt-on design and include 1" lift spacers to accommodate lifted setups. There’s no tubing or air pressure to monitor—just reliable performance every time you hit the trail.

Video Transcript for Detailed Breakdown of the SumoSprings Solo Custom Helper Springs for Jeep

Today we're going to take a look at the SumoSprings solo custom helper springs with the two inch lift spacers for a Jeep front axle. Now this is a custom fit part. It is designed to fit the 2007 to 2018 Jeep Wrangler JK models. On a custom fit part like this, I always like to recommend for you to go to our website, use the fit guide, put in your year and model vehicle and it'll show if this will work for application.Now these are off-road helper springs that'll upgrade your vehicles front suspension for improved control and comfort, helps absorb big bumps and shocks that can occur when you're driving over rough terrain. It'll even help minimize sway for better control when you're rock-crawling. Supports heavy front end loads like winches or aftermarket bumpers to keep your Jeep level.

It gives you faster activation because the springs are taller so that they engage more quickly than standard helper Springs.If you notice right here at the top, we've already put them on here, but they do include these two-inch spacers to accommodate your lifted Jeep. These do give progressive load control, which means the springs will compress according to the weight of your cargo. So if it's a lighter load, the springs compress easily at first for soft engagement, less bumpy ride. If it's a heavy load, the springs will compress by as much as 80% for support.They are made of a durable high-density micro-cellular urethane. They are designed to work in temperatures from a negative 25 degrees Fahrenheit up to 200 degrees Fahrenheit.

They do resist damage it can cause by oils, road salts, UV rays. They offer minimal lateral expansion. The springs will expand and compress vertically instead of the sides so they aren't easily damaged when operating in tight spaces. They are maintenance free. There's no tubing to run or air pressure to monitor like with air springs.It is a no-drill bolt-on installation.

Comes with everything shown here, the two springs, the two lift spacers. All the hardware is included. They even include a nice tube of thread-locker when you go to install it, and a nice set of detailed instructions that'll describe your installation. These parts are made in the USA. Specs on it, the weight capacity at 50% compression is 1400 pounds.

You do need to remember SumoSprings will not increase your vehicles weight carrying capacity. As we mentioned, these come with the lift-spacers, which are two inches tall. But that should do it for the review on the SumoSprings solo custom helper springs with the two-inch lift-spacers for the Jeep front axle.

Good product, length was to long and had to shorten it 2 "rings" to allow up travel and not contact stop on every bump. I installed a 2.5" clayton coil spring lift and the between the new lower stops summo springs was only 2" of travel. Might be fine on factory vehicle without lift. These are a huge improvement over factory bump stops that had very little cushioning effect.

I put these on my 2017 2 door jeep wranger. I have factory springs no lift. I put on aftermarket front bumper with wench, rear bumper, roof rack. With all the other gear in the jeep, frig, and all camping gear, and plans on putting on a rooftop tent. The ride was a harsh because off all the extra weight, so i thought i would give it a try. I first got air bags for the rear and they worked great, improving the ride, but now the front was still harsh. So i thought i would try the sumosprings. All i can say about the sumosprings is that there awesome. I can now go over bumps on dirt roads, paved roads, train tracks, and it dosnt beat the crap out of me. Jeep feels like its happy.

SumoSprings for the front end, the provided bolts are the exact size of the holes in the frame. Had to keep forcing them till it started to thread then use plyers to hold it in place. Very tough to get it but it went it. Have a 2006 Pleasure Way Dodge Sprinter 2500 RV Class B.

I used them as high speed bump stops. They work great and much cheaper than air bumps.

I am sure these would have helped the Gladiators without the factory Fox hydraulic bump stops but in my case I returned my purchase I opted not to replace my Fox hydraulic bump stops in the Mojave.

    For your 2020 Jeep Gladiator, I recommend the Blue SumoSprings Solo Custom Helper Springs item # SS42XR.

The more weight you place on them the more they engage. This provides you with only the support you need when you need it.
