The 1963-72 Chevy Pickup Rear Level 3 Airbag Dropmember suspension system is engineered to lay frame with large diameter wheel/tire combinations.

It is available in a trailing arm configuration. Ride height measures approx. 4” when running a 30” tall tire, and the frame will rest on the ground when deflated (measurements are taken from bottom of the frame rail under the cab to the ground).
