The Air Lift 57230 LoadLifter 5000 Rear Air Spring Kit is a heavy-duty suspension upgrade designed to improve load support and stability for pickup trucks. It is engineered to assist vehicles that frequently tow trailers, carry heavy payloads, or operate under demanding conditions.

The bolt-on installation makes it accessible for most users without requiring complex modifications.

This kit is compatible with a wide range of 3/4-ton and 1-ton trucks equipped with rear leaf spring suspensions. However, exact fitment depends on the specific vehicle configuration, and users should verify compatibility using the manufacturer's official application guide. Fitment may vary across trims, drivetrains, and model years, and 2025 coverage is dependent on confirmed applications for each platform.
