MMR's Engine lift plate installs in just seconds with the hardware provided. Made from Thick Billet aluminum plate it wont rust and features a easy to use hook that will lift up to 6000lbs!! These are raw Aluminum lift plates, although we take every precaution to prevent damage, scratches may still exist as part of either the manufacturing process or shipping/handling within the Amazon warehouses. Any scratches to the surfaces in NO WAY affects the functionality of the tool. START ALL BOLTS BY HAND FIRST BEFORE TIGHTENING ANY BOLTS - OTHERWISE YOU WILL END UP LIKE THE JACKASS WHO LEFT A 2 STAR REVIEW AND SAID ONLY 1 BOLT SCREWED IN - COMMON SENSE HERE GOES A LONG WAY.
