The Air Lift 52440 Universal 4in Straight Air Spring Spacer is engineered for lifted trucks to restore the towing and hauling performance lost during suspension modification. This 4-inch level spacer bridges the gap between the vehicle frame and bellows-style air springs, ensuring the air suspension system operates at its ideal height to eliminate squat, poor headlight aim, trailer sway, and bottoming out.

Constructed from high-grade 1/4-inch steel with a durable black powdercoat finish, these spacers are built for extreme durability and corrosion resistance. The unique spinal design facilitates a secure and straightforward connection to the air spring using the provided hardware. This kit is compatible with Air Lift LoadLifter 5000 and LoadLifter 7500 XL series, as well as most other bellows-style air spring brands on the market.
