Bushing’s Three Functions (Tri-Functional)

Hendrickson’s bushings control three primary road forces: Vertical Forces • Voids expand and compress to absorb road induced forces allowing optimum suspension articulation without over stressing the axle • Ride quality and payload protection surpass other bushing designs

Horizontal Movement • Solid rubber areas resist forward and backward movement to maintain suspension tracking and alignment during braking and acceleration

Roll Stability • Voids allow increased articulation to provide exceptional control during turning and roll events • The special void shapes enhance the axle’s ability to act as a torsion bar, resisting trailer roll forces

Hendrickson Genuine Parts are the same quality components installed in Hendrickson original equipment suspensions — consisting of the same design, construction, performance and durability. There’s only one way to maintain and protect your suspension’s original performance. Ask for the name that is synonymous with the finest manufactured suspensions in the world.
