Heavy front-end loads like slide-outs or gear can cause sag that throws off steering and braking. These SumoSprings Rebel helper springs add up to 3,000 lbs of support at 50-percent compression to keep the front end level and stable. The microcellular urethane material cushions bumps and absorbs road shock so your ride feels smoother and more controlled even when the weight piles on.
Uneven pavement or rough terrain can make a heavy vehicle bounce and jar uncomfortably. The two-piece design of these springs lets the suspension move freely when unloaded, separating under light conditions for a soft, comfortable ride. When loaded, the halves meet to deliver full support that keeps suspension travel unrestricted without harshness.
Not every trip carries the same weight, and these springs adjust automatically. Lighter loads compress the urethane easily for gentle engagement, while heavier ones push the springs up to 80 percent of their travel for firm support. The result is a steady, even stance whether you’re lightly packed or carrying serious weight.
Body roll and off-center loads can make steering feel loose in curves or gusty conditions. Each SumoSpring works independently to balance side-to-side pressure, keeping handling consistent through turns and crosswinds. That independent movement helps reduce sway and keeps all four tires making solid contact with the road.
Road salt, oil, and UV rays can break down weaker materials fast. These microcellular urethane springs resist abrasion and weather damage while performing reliably from -25°F to 200°F. They expand and compress vertically with minimal side movement so nearby parts stay protected. With no air lines or pressure checks to worry about, you bolt them on once and they’re ready for the long haul.

Put quite a few miles on them since purchase. Made a noticeable difference in sway and ride. Would buy again.

Great no change to my original review. I put the the Sumosprings decal on my windshield so others can see what I have to make our ride less jolting.

Sway bars and springs are still working great. They are a necessity for my Ford F-53 chassis.

After looking into your order, it looks like you have a 2 wheel drive F-53 chassis with a gross vehicle weight of 22,000 lbs. And that may be the issue. It looks like this kit is designed to fit your chassis if the gross vehicle weight is between 24,000 and 26,000 lbs. You will actually need part # SSF-170-40-2. Lets go ahead and get a return label set up for you and a new order placed for the correct part.
