The Kelderman Stock Height 4-Link Rear Air Suspension system improves ride quality and towing for heavy-duty trucks. It replaces factory leaf springs with a durable 4-Link Rear Air Suspension, including industrial-strength air bags (rated for more weight than original leaf springs), mounting plates, trailing arms, axle clamps, rear crossmember, panhard bar, upgraded sway bar, end links, hardware, air line, fittings, and Schrader valves. An optional self-leveling air control system provides onboard air, automatic ride height adjustment with trailers, and the ability to lower the truck by approximately 4 inches for easier loading and trailer hook-up.
