JEGS Solid Aluminum Leaf Spring Bushings are designed to reduce deflection and axle wind up inherent with O.E. rubber bushings to eliminate wheel hop and excessive pinion angle. Ideal for racing purposes. Kits include two aluminum bushings and two steel bushing sleeves for use with 9/16" bolts. We've added two grease fittings to each of our kits to eliminate binding thus allowing free movement to allow the axle to drop (pushing the tires into the pavement for more traction) and the body to lift under acceleration. Fits 1967-81 Camaro/Firebird and 1968-79 Nova. Made in USA.
