Product Description

The Air Lift 57204 LoadLifter 5000 is a rear air spring kit engineered for the 2007-2018 Chevrolet Silverado 1500, GMC Sierra 1500, and their 2019 carryover successors -- the Silverado 1500 Legacy and Sierra 1500 Limited -- delivering up to 5,000 lbs. of load-leveling capacity for heavy hauling and towing. Built with 2-ply reinforced commercial-grade bellows mounted between the existing leaf spring and frame, this kit reduces sag, sway, and bottoming out while maintaining a comfortable ride whether loaded, towing, or running empty.

Fully adjustable from 5 to 100 PSI, this kit lets owners dial in exactly the right support for the load and road conditions at hand, and can even be adjusted side-to-side to level out uneven loads. Included roll plates protect the air springs from damage, and Zytel nylon end caps deliver the strength of steel at a fraction of the weight, with full corrosion resistance for long-term reliability.

Installation requires no frame drilling and takes about two to three hours, with an illustrated instruction manual and easy-to-use manual inflation valves included (an air compressor is not included but can be added separately). This kit is specifically sized for 68" and 78.8" bed lengths and is not compatible with MagneRide-equipped trucks -- confirming your Silverado or Sierra's bed length and suspension package before ordering ensures a proper fit. Built for 1500-series truck owners who need serious, adjustable load support for towing and hauling without sacrificing everyday ride comfort.
