1,800-lb Capacity. Upgrade your vehicle's rear suspension with these maintenance-free helper springs. Sturdy microcellular urethane springs cushion bumps and help support a heavy load to level your ride and minimize sway. No-drill installation.
Features:
Specs:
Towing or hauling a heavy load can cause rear sag as your factory suspension compresses under the weight of the load. This means that the rear axle is trying to support not only the extra load but also the weight of your vehicle. And because there is less weight on your front axle, your front tires make less contact with the road, which causes problems with traction, steering, and braking. SumoSprings upgrade your vehicle's factory suspension to level your vehicle, improve driving performance, and keep your ride comfortable.
SumoSprings provide progressive load control - the more you load them, the stiffer they become. With a lighter load, the springs will compress easily for soft engagement and a less bumpy ride. The closed-cell urethane material allows for smooth contact between the springs and your vehicle. And the springs act like a shock absorber to dampen road vibration.
The springs can also compress by as much as 80 percent to support a heavy rear load and to help your factory suspension bear up under the load. This evens out the weight, which levels your vehicle and ensures that your front tires are making better contact with the road. A level ride means that you have improved driving control, ensures safe headlight aim, and helps to minimize sway. The springs also support your factory suspension, which helps prevent sagging and reduces bottoming out.
The springs work independently from one another to support each side of your vehicle. This action helps to reduce body roll when you make a sharp turn. This also helps compensate for an off-center load.
These microcellular urethane springs are tough. They resist abrasion, oil, salt, and UV rays that can more quickly wear out other springs, and they perform well in temperatures ranging from -25 F to 200 F (-33 C to 93 C).
SumoSprings compress vertically with minimum expansion to the sides, so they won't be damaged by nearby mechanical parts and they fit safely into tighter spots. And unlike air springs, SumoSprings require no maintenance or adjustment.
The helper springs are custom designed to fit your vehicle, and they install easily - no drilling required.
Jeep Gladiator Mojave - swapped out the rear stock bump stops with these. High quality parts. Just jack up the truck enough to give you room to work with and put in your jack stands, no need to remove the wheels. I look forward to seeing how they do with towing! Hopefully I can update my review here afterwards. Check out the gap difference in the pictures. Should touch sooner during normal drive conditions and hopefully help reduce some trailer squat and help towing to be smoother.
For my 1024 jeep gladiator.Very easy installation. I personally found it easier to just go ahead and remove the tire, it gives you straight access to the installation point.
I have had these on my Jeep Gladiator for over a year now and I still like them. Sumo Springs really help with sag when towing my Scamp camper trailer and when the truck bed is loaded with stuff. When it is cold outside they are stiffer and I can feel when they hit the stops on hard bumps. Sumo Springs are a very easy overload spring option with factory lift.
Super easy to install as I did not have to use any tools. Replaced the short foam bump stop from the factory.
Easy to install on my Jeep Gladiator. I've used the Gladiator to pull a 23ft rv trailer also with the weight distribution hitch. The unit runs level without any squat. I think it is a good add on.
Easy install. Just raise the rear of the truck enough to get the old bumps out which was very easy, place a little dish soap on the sumo spring to aid in the install, lower the rear of the truck and the springs should pop right in. If you have a lift kit place a block of wood between the sumo and bump stop plate.
Simple install on my 2020 Jeep Gladiator. These springs seemed to help when towing our travel trailer.
Work awesome on keeping my Gladiator level while pulling my travel trailer!
