Summary:
The LoadLifter 5000 Ultimate is an adjustable air spring kit designed to provide up to 5,000 pounds of load leveling capacity. This system features a rubber air spring with an integrated internal jounce bumper made of closed-cell urethane foam and is intended for frame-mount installation.

This product is intended for load support or component replacement only and does not alter factory suspension geometry unless explicitly stated.

• Construction Materials: Features 2-ply fabric reinforced air springs and end caps made of high-strength nylon composite for corrosion resistance.
