Application: Works for all LS series engines - 4.8 5.3 5.7 6.0 LS1 LS2 LS3 LS6 L99 LS4 LS9 LSA LQ4 LQ9 L76 L92.
Function: Helps align the front and rear engine covers to make sure the cover is centered. A centered cover means less of a chance for a seal to leak.
Nice Design: Cover Alignment Tool mimics the balancer to center the cover on the front seal OR locates on the ID of the seal bore in the cover without the seal installed; The Oil Pan Alignment Tool mimics the oil pan thus providing critical alignment of the oil pan and front cover.
Please Note: For LS engine, the oil pan is a stressed member and adds to block rigidity. Due to this reason, it can't simply be slapped in place, you will have to aligned the cover to the oil pan carefully.
Superior Material: Crafted from Billet aluminum & Quality steel with great durability and tight tolerances for a perfect alignment. Perfect for engine builders and mechanic to replace the front or rear main seal for GM LS series engine.
