2011–2019 Silverado/Sierra 2500HD/3500HD Air Lift LoadLifter 5000 Ultimate Air Spring Kit

The Air Lift LoadLifter 5000 Ultimate Air Spring Kit provides superior rear suspension support for trucks that regularly tow or haul heavy loads. Its internal jounce bumper allows the air springs to maintain performance and protection even at very low air pressures, ensuring a smooth, controlled ride under all load conditions.

This system helps eliminate rear sag, improves handling, maintains proper headlight aim, and reduces bottoming out during heavy towing or uneven loads. Adjustable air pressure allows users to fine-tune ride height and firmness for changing load weights or driving conditions.
