Fits 2017-2022 Ford F-250 and F-350 Super Duty SRW 4WD models with block-style lift kits.

The Air Lift LoadLifter 5000 kit (MPN: 57409) provides up to 5,000 pounds of load-leveling capacity, engineered specifically for Ford Super Duty trucks equipped with leaf spring block spacer-style lifts. This side-mounted kit eliminates the common issues of towing and hauling heavy loads, including rear-end sag, trailer sway, body roll, and bottoming out. By maintaining a level vehicle, it ensures proper headlight aim and improved steering control.

Built for durability, these air springs feature 2-ply fabric reinforcement similar to tire construction. The ultra-high-strength nylon composite end caps are corrosion-proof and as strong as steel but significantly lighter. This kit includes upper and lower roll plates to protect the bellows from sharp edges and increase the load-bearing surface area. The underframe design is compatible with most in-bed hitches, including factory and aftermarket 5th wheel hitches.
