2,800-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.
Great product! Bought these for my 2000 7.3 f250. Didn't want something that is constantly active like ras or hellwig since my leaf springs are new and rated for 4k pounds. Installed these in 1 hr super simple only hard part was the factory bump stop on driver side was a pain. Didn't install the puck they give due to height of truck and I knew more or less at what point I wanted them engaging. I haul cattle to shows/ auctions or between pastures with my 24ft big bend and these things actually provided a smoother ride in my truck loaded then unloaded.they do a great job with the added support and are better than an overload spring with handling sway and providing a smooth ride loaded. Just wish I could use the 3k pound rated ones on this truck and my dually but doesn't fit if you have a gooseneck sadly so will probably have to go with timbs on the drw. Over all great product can't speak to longevity but solid for the time being. And customer service with this company is excellent if you have a question or problem they're on top of it...hope they pay them as well as the reputation they're building for them.
F250 superduty xl pulling large fithwheel toy hauler, rides smooth, only couple inches drop.makes me feel like I can go 80(but obviously dont)
Easy to install and so far the ride seems more stable.
So far so good. Easy installation without removing the wheels.
The springs are great but I ordered the blue ones and received the yellow ones. They make the ride of the truck without a load in it rough. Roads around my area are not the greatest and these springs let you know it. Loaded down on the other hand is much improved. Over all good but will be switching to to the blue ones.
Great service and on top of orders.

Working well. The truck rides better and hauls better since installing the SuperSprings.
