The Hendrickson Primaax EX suspension is ideal for vocational and severe duty applications. 

Key features include higher roll stiffness; reduced roll steer coefficient; increased lift capacity; no-lube, heavy duty bushings for reduced maintenance; and redesigned U-beam assembly, air spring, torque rod bracket and frame bracket for increased robustness and durability.
