Slam™ Rear Lowering Air Suspension Spring Kit with 5.8" Rear Body Drop (75690) by Air Lift®. This is a set of adjustable secondary air support springs designed for trucks that have already been lowered from 2 to 6 inches. Together, they add up to 2,000 pounds of leveling capacity to restore most if not all that has been lost due to reduced suspension travel. Air pressure in the springs is manually adjusted between 5 and 100 psi.

The suspension of any pickup, van, or sport utility that’s weighed down by heavy cargo, permanently affixed equipment, or a trailer is compromised because the rear springs are crushed down to a height they cannot recoil from. Ride quality is reduced, and the front of your vehicle points upward. A rear end that is weighed down literally lifts weight off your front wheels, reducing the amount of traction you have for steering, and reducing the amount of grip the tires have on the road when you need it in fast braking. If you have lowered your vehicle with reduced height springs, the effect can be even worse

Air Lift’s Slam Air Kit has been created just for vehicles that have lowered springs. A set of adjustable helper air springs mount to the rear of your vehicle and can lift up to 2,000 pounds of the weight that’s causing your truck to ride low. Once your vehicle’s back up to a level ride height, headlights and bright lights stay at the correct aim so the road ahead of you is illuminated, not the tree tops in the distance. And instead of putting yourself at risk by blinding other drivers, you can focus on how best to avoid the potholes up ahead that are no friend to lowered vehicles. Air is added and released manually to the Slam Air Kit springs, so the system is simpler and more cost effective. Air Lift proudly produces the Slam Air Kit in the United States, and backs all components with a limited lifetime warranty against failure due to manufacturing defects.
