Leaf spring sliders bolt on in place of shackles. Heavy duty versions feature roller bearings that keep car from binding up during suspension movement. Designed and intended to work only with the Chrysler type mono-leaf and multi-leaf racing springs. 3-1/2" wide. 6-5/16" long. 2-9/16" tall. Width of flange is 4-1/2" Mounting holes on width are 1-13/16" center to center. Mounting holes on length are 3" and 5-1/16" Comes with brass bushing for 1" I.D. spring eye.The AFCO leaf spring sliders can eliminate the up and down movement of the rear spring eye caused by shackles moving through their arcs during suspension travel. Consequently, the rear suspension's loading points displace less during suspension movement. Sliders, depending on their installed angle, generally reduce the "shackle effect " and provide more consistent spring rates than shackles. There is no "shackle effect " to the rate of the spring when the slider is mounted to point directly at the front spring eye center (this is the preferred mounting position). Since sliders are usually more rigid than shackles, they have less tendency to bind laterally during cornering. In general, sliders improve the handling consistency and predictability of leaf spring equipped race cars.The AFCO leaf spring sliders can eliminate the up and down movement of the rear spring eye caused by shackles moving through their arcs during suspension travel.
