Air Lift 77384 LoadLifter 5000 Pro Series Air Spring Kit for Leaf-Spring Suspensions

The Air Lift 77384 LoadLifter 5000 Pro Series Air Spring Kit is a heavy-duty rear suspension upgrade engineered for trucks and vans equipped with leaf-spring suspensions. Delivering up to 5,000 lbs. of load-leveling capacity, this kit helps eliminate the common problems associated with towing and hauling heavy loads — including rear squat, trailer sway, body roll, poor headlight aim, and bottoming out.

Built for durability, the air springs feature 2-ply, fabric-reinforced rubber construction with corrosion-proof Zytel nylon end caps that are both lighter and stronger than traditional steel end caps. Exclusive upper and lower roll plates protect the air springs from abrasion while maximizing load capacity and longevity.

Key Features:

• Up to 5,000 lbs. of rear load-leveling capability
• Adjustable inflation from 5 PSI to 100 PSI for precise load tuning
• Inflate both springs equally for towing, or independently for side-to-side leveling of uneven loads
• 2-ply, fabric-reinforced rubber air springs for maximum strength and durability
• Corrosion-proof Zytel nylon end caps — lighter and stronger than steel
• Exclusive upper and lower roll plates protect springs from abrasion
• Helps restore proper headlight aim, steering, and braking performance when loaded
• Compatible with optional Air Lift compressor systems and wireless controllers
• Installs using common hand tools — all mounting hardware, air lines, and manual valves included
• Backed by Air Lift's limited lifetime air spring warranty with no mileage restrictions

The LoadLifter 5000 Pro Series integrates seamlessly with the existing factory suspension system, providing full-time load support whether you're towing a trailer, hauling a heavy payload, or running unloaded. The complete kit includes all necessary mounting brackets, hardware, air lines, and manual inflation valves for a straightforward installation.
