The Superpro leaf spring eye bushing for Ford and Mazda is an upgrade for 4WD rear suspension, stabilizing axle movement and reducing passive steer and wandering under heavy braking or when towing. Combined with greaseable shackles, SuperPro parts are intended to let the rear end handle heavier loads and tougher conditions while improving overall stability compared with worn rubber bushings.
