This sleeve-style cabin air spring seats the cab onto the chassis and provides dampening to improve ride comfort and vehicle handling. Engineered to meet OEM specifications, it serves as a direct replacement for the factory air spring, restoring proper suspension travel and ride height. Its sleeve design offers a maximum diameter of about 4.90 inches, a maximum height of 13.80 inches and a collapsed height of 2.40 inches, delivering the travel needed to absorb bumps and maintain a consistent cab height. Supplied individually and weighing roughly 17 lbs, it restores smooth ride quality while integrating seamlessly into the vehicle’s air-suspension system. The Mack 21128983 spring ensures the correct fit and performance for your truck.
