Superlift's "flip kit" provides 4" of lift by converting the factory rear spring shackles from a tension style (pointing up) to a compression style (pointing down). This allows the custom builder to decrease block and/ or lift spring height for improved suspension flexibility.
The need to address pinion angle, via spring shims, varies depending on numerous factors.
Kit includes a pair of new shackle hanger brackets, laser cut and constructed of .25" plate steel, and mounting hardware.
