Heavy trailers, campers, or bed loads can cause your rear end to sag and throw off your steering and braking. These SumoSprings Solo helper springs add up to 1,400 lbs of support at 50-percent compression to keep your ride level and steady. They help your factory suspension handle the extra weight so your front tires stay in contact with the road and your headlights stay aimed right where they should.
Not every load is the same. These microcellular urethane springs compress easily at first for soft engagement when lightly loaded and can compress by as much as 80 percent under heavier weight. That progressive action keeps the ride smooth when empty but firm and stable when loaded, reducing harshness while maintaining control.
When a curve or crosswind tries to push you around, each spring works on its own to keep its side planted. This independent action helps compensate for uneven loads, cutting down on body roll and sway so your vehicle feels stable through turns or when entering driveways at an angle.
Made from durable microcellular urethane, these springs resist oils, road salts, and UV damage while performing in temperatures from -25 F to 200 F. They compress and expand vertically with minimal side movement so nearby components stay safe even in tight spaces. With no tubing, air pressure, or maintenance needed, they provide reliable support trip after trip with simple bolt-on installation and all necessary hardware included.

That's the beauty of SumoSprings, easy to install and once they're on you can forget about them and let them do their job!
