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 contract and provide total isolation. The inserts and thrust washers also provide a bearing surface for the bushing. This design makes the bushings operate similar 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, 1 inch longer shackles, and related thrust washers, inserts, and hardware.
The longer shackle kit raises rear end ride height by 3/8 to 5/8 inch on an inch based on the arc of the leaf spring. With These shackles, you wouldn’t need to modify the leaf spring to get that extra clearance. This makes the process quicker and easier.
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.
