Apoc Industries Lift blocks are are built to outperform factory blocks or the infamous stacked blocks that most lift kits use in their kits. Our Antiwrap lift block design gives twice the foot print on the leaf spring to help reduce leaf spring wrap and wheel hop on launch. Apoc also adds multiple holes on top to help recenter the axle in the fender or to shorten the distance from the transfer case the help reduce vibrations, along with a 3 degree taper to reduce pinion angles. All lift blocks are full spring width for added stability along with a locking center pin that is sized to match factory axle centering pins
