Leaf springs are a thing of the past. Take your truck’s customization to the next step with a Kelderman 4-Link Rear Air Suspension Lift Kit! This kit is designed to provide your Ram 2500/3500 with an 8-10″ ‘ride height’ for traveling down the road. When deflated, this kit can drop to approximately a 4″ lift to help you load items in the bed or hook up to trailers. When using our 8-10″ 4-Link Front Air Suspension Lift Kit you can drop down to a 4″ lift and park inside a standard 8′ tall garage door! The 8-10″ 4-Link Rear Air Suspension Lift Kit provides you with all the necessary suspension components to convert your truck from a rough leaf spring suspension to a smooth, capable air suspension system. This kit includes trailing arm mounts, adjustable trailing arms, upper and lower air bag mounting plates, axle clamps, industrial strength air bags, rear crossmember, adjustable panhard bar, upgraded rear sway bar, sway bar end links, shock mounts, and our ‘manual fill’ air control package. This will allow you to inflate the suspension tot the 8-10″ ride height using a Schrader valve. Several air control options are available including our SLKD2WD Air Control System which will allow you to lower the rear suspension for easier access to the bed and let the truck automatically adjust for the weight of cargo and trailers. You won’t have to worry about a trailer turning your 8″ lift into a 5″ lift because the leaf springs can’t handle the weight. This kit will automatically return to the 8-10″ ‘ride height’ and not strain your suspension. When setup with an 8-10″ 4-Link Front Air Suspension Lift Kit and the optional Air Lift 3H Electronic Air Control System you can adjust the kit up even higher to a 14″ lift kit. This is great for extra clearance in certain situations or showing off. The kit can then adjust down to the 8-10″ ‘ride height’ for a comfortable drive down the road.
