The Air Lift 57338 LoadLifter 5000 Helper Spring Kit is specifically engineered for your 2011-2019 GM 2500HD/3500HD Pickup while towing and hauling your heaviest loads with full-time load support. These tough, durable air springs provide up to 5,000 pounds of leveling capacity and are fully adjustable to keep your vehicle riding stable, level and comfortable whether loaded or unloaded.

Air Lift adjustable air springs work with your existing suspension to give our vehicle more leveling support when you need it, so your vehicle is always level and stable. Proper weight distribution to all tires means more safety and a more comfortable ride as well. This results in:

Improved braking and steering: when all four tires are firmly on the ground, braking time and steering are both improved.

Less sway: Air springs increase spring rate and vastly improve vehicle stability.

Less bottoming out: Air springs provide adjustable load support to help prevent bottoming out on rough roads.

Headlight aim: Only level and stable vehicles provide safe and proper headlight aiming.

More even tire wear: when weight is evenly distributed to all four tires, tires wear more evenly.

Less porpoising: Even heavy pickups which don't squat when loaded can begin to porpoise vertically when towing heavy trailers. Adjustable air springs dramatically reduce this problem for a safer, more comfortable ride.

The kit includes 2 air springs, brackets, air lines, Schrader valve and all of the hardware you need for installation. LoadLifter 5000 air spring kits are engineered to be installed in under 2 hours and include a fully illustrated, user-friendly instruction manual.
