BLEM PRODUCT-This product is laser marked to identify it as a blemished item.

This product was machined with 8mm instead of 6mm threads at the bottom surface where the Oil pan connects, These BLEMS will require you to drill your oil pan and gasket from 6mm to 8mm to use this item. We have included the larger 8mm Bolts to help with the installation. 





This 1/2 inch billet aluminum CNC machined plate replaces the factory rear main seal housing cover. Its thick CNC construction helps support the rear of the block and provides a stable housing for the rear main seal to 100% Eliminate leaks and increase block strength & stability. The MMR design eliminates messy, leaking silicone / RTV by using a high quality, leak free replaceable Viton O-ring gasket.
