Air Lift LoadLifter 5000 Air Spring Suspension Kit

The Air Lift LoadLifter 5000 is a heavy-duty air spring suspension kit engineered for trucks and vans that regularly tow trailers, haul cargo, or carry heavy equipment. Designed to integrate seamlessly with existing leaf spring suspensions, the LoadLifter 5000 series delivers up to 5,000 pounds of load-leveling capacity — keeping your vehicle stable, level, and in control whether fully loaded or running empty.

Common towing and hauling problems — including rear squat, trailer sway, body roll, suspension bottoming out, and poor headlight aim — are effectively addressed through a fully adjustable air spring design. Air pressure is tunable across a wide range, allowing drivers to dial in precise support for any load condition without exceeding the vehicle's GVWR.

Key Features:

• Up to 5,000 lbs. of load-leveling capacity — engineered for serious hauling and towing applications
• Fully adjustable air pressure — tune support to match exact load and driving conditions
• 2-ply fabric-reinforced rubber air springs — constructed like a tire for maximum durability and long-term strength under heavy loads
• Roll plates included — protect air springs from frame edges and sharp contact points while increasing load capacity
• Ultra high-strength nylon composite end caps — deliver steel-like strength without added weight or corrosion risk
• Seamless leaf-spring integration — mounts to existing suspension without altering stock ride height
• Complete hardware included — each kit contains air springs, air lines, fittings, brackets, mounting hardware, and instructions
• Limited lifetime air spring warranty — backed by Air Lift with no mileage restriction
• 60-Day Money-Back Guarantee — Air Lift's no-risk ride satisfaction guarantee on all load support air springs

By restoring a level ride height under load, the LoadLifter 5000 improves braking performance, steering responsiveness, and headlight alignment — critical safety advantages when towing heavy trailers or hauling maximum payloads. Trusted by contractors, RV owners, fleet operators, and weekend haulers, the LoadLifter 5000 line offers proven, bolt-on air suspension support across a wide range of full-size pickup truck and van applications. Compatible with optional on-board air compressor systems, sold separately, for added convenience and on-the-fly pressure adjustment.
