1967 - 1981 Firebird Del-A-Lum Rear Leaf Spring Bushings and Shackle Kit

Rubber and polyurethane will allow the rear portion of the leaf to walk laterally. If the front bushing is solid mounted, the length of the leaf becomes a long torque arm reacting on the forward mounting point. It is trying to rip the mount out of the car. The solution is to use a Del-A-Lum shackle kit and remove the problem.

The Del-a-lum bushings do not allow the leaf spring to move laterally, removing the torque effect of the leaf. They also allow a choice of preloading the bushing for decreasing leaf spring movement or running no preload and increasing leaf spring movement.

Del-A-Lum Shackle Kits: A bushing that works like a bearing!

Del-A-Lum bushings are perfect for street, drag and autocross applications. Installation requires the bushing housings to be pressed into the frame and the leaf spring eyelets. Inserts and thrust washers separate the housings and springs from metal-to-metal contact and provide total isolation.

The inserts and thrust washers also provide a bearing surface for the bushing. This design makes the bushings operate similarly to a bearing. Grease fittings are installed and the housing is grooved internally for grease penetration. Del-A-Lum bushings also provide lateral control of the leaf springs.

NOTE: Del-A-Lum shackle kits are shipped complete with front and rear eyelet bushings, frame bushings, shackles, and related thrust washers, inserts, and hardware. Proudly made in the USA!
