Installation Notes

Replacement requires a separate left and right fill system with an AK18 or AK64 Air Line Kit. Verify mounting dimensions, sleeve ID, and rear suspension configuration before installation. Follow the vehicle owner’s manual for load limits and pressure settings, since capacity is limited by the suspension, tires, and transmission.
