Why Choose ATRO Suspension Bushings?

Unlike conventional rubber bushings that rotate inside the spring eye and eventually wear the suspension, the ATRO PB46-26268 features a rotating pin design with an anti-walk flange that keeps the bushing securely in place. Combined with ATRO's premium polyurethane construction, this design delivers significantly longer service life and improved suspension reliability in demanding commercial truck applications.
