Upgrade Your Trailer's Suspension These Sumo Springs for trailers provide improved driver control and comfort, so you can experience a smoother, more comfortable ride. With the ability to support heavy rear loads, you can keep your vehicle level and eliminate the dreaded sag that comes from a heavy cargo load. Say goodbye to jarring bumps on the road, as these springs help to absorb them with ease. Plus, you'll experience less sway, so you can stay firmly in control even when taking sharp turns.. Low Maintenance 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.. Enhances Load Carrying Ability When you're carrying a heavy load, your factory suspension can compress, causing your rear axle to bear the weight of both the extra load and your vehicle. This leads to sag, which can cause problems with traction, steering, and braking. But with SumoSprings, you can upgrade your vehicle's suspension. These progressive springs adjust to the weight of your cargo, compressing more for heavier loads and less for lighter loads.. Weight Capacity SumoSprings will not increase your vehicle's weight-carrying capacity. These springs have a 1000 lb Capacity at 50 Compression.. Easy to Install SumoSprings are custom designed to fit your vehicle and install easily with no drilling required.
