Susp Leveling Kit

Restore load carrying capacity and eliminate bottoming out by adding SlamAir air helper springs to your lowered vehicle. SlamAir kits supplement a lowered truck's leaf springs to provide adjustable spring rate for ride comfort, safety and variable loads. Easy to install between your existing springs and the vehicle frame, they are made with rugged, durable components for long, reliable service. Air Lift SlamAir kits fit most lowered trucks with a 2 -- 6 inch drop, including trucks with flipped axles and notched frames. SlamAir air helper springs are air adjustable from 5 to 100 PSI and come with quick connecting, easy-to-use air fittings. They also come standard with a limited lifetime warranty and an exclusive 60 day ride satisfaction guarantee.

Reference Information

Leaf Spring Leveling Kit, Slam Air, Adjustable Air Springs, For Lowered Trucks, Rear, Lowered 2-6 in. Pair

Lowering a truck typically reduces suspension travel and load-carrying capacity. Air Lift's SlamAir air-spring helpers can relieve those conditions, adding up to 1,800 lbs. of leveling capacity. They fit between the frame and leaf springs on trucks lowered from 2 to 7 in., even those with flipped axles and notched frames. You can put the air valve about anywhere on your vehicle with the 16 ft. of hose provided. Installation takes about two hours, and mounting hardware and detailed instructions are included. Give your vehicle more leveling support when you need it, so your vehicle is always level and stable.
