When heavy gear or a trailer pushes down on the rear, handling and braking can go off balance. These SumoSprings Solo Custom Helper Springs add up to 1,500 lbs of support at 50-percent compression to help your suspension stay level and keep steering responsive. They cushion bumps, minimize sway, and reduce bottoming out when carrying serious weight.
Whether the bed is empty or loaded down, the springs respond to the weight automatically. With lighter loads, they compress easily for a soft, smooth ride. As the load gets heavier, they stiffen up—compressing by as much as 80 percent—to give firm support and keep the rear from sagging. The progressive design means no harsh jolts on rough roads and stable comfort mile after mile.
Each spring works on its own, so one side can handle a heavier or uneven load without throwing off balance. This independent action helps reduce body roll when turning sharply and keeps your vehicle planted when crosswinds or uneven surfaces try to push it around.
These helper springs are made from microcellular urethane that stands up to abrasion, oil, salt, and UV rays. They keep performing in temperatures from -25 F to 200 F without deformation or cracking. Because they compress vertically with minimal side expansion, they fit tight spaces without rubbing nearby parts.
Installation is no-drill and straightforward—just bolt them on and you’re done. There are no airlines or valves to run and no air pressure to monitor later. Once installed, the springs work automatically every time you tow or haul.

I have been using SumoSprings Solo Custom Helper Springs - Rear Axle for about a year. I installed these helper springs after adding a rear tire carrier and additional spare, replacement bumper heavier, and 4 gallon fuel can on the rear of my 2008 Nissan Xterra. I was hoping they would help eliminate rear end recoil when going over large bumps or dips while off road due to the increased weight on the extreme rear of the vehicle. These progressive springs do an impressive job on remedying my issue. I have much less bounce from the rear end after installing the srings and they have continued to be effective. I highly recommend.

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?
