These block plates allow you to now mount a Chevy LS motor (Gen III & IV) if you already have our JM200 or JM400 motor mounts by just swapping the block plates. Now that rock crawling has become the favorite past time for Jeepers and we are putting our Jeeps in places that they were never designed to go, the stresses on the stock Jeep motor mounts are tremendous. With deep gearing, big tires, lockers, and mega torque, the stock mounts can be torn apart in no time at all. That is where these "Bomb Proof" motor mount kit products come into play. They bolt into stock holes in the frame and engine (in some applications, drilling and/or welding may be required). In most applications, our "Bomb Proof" motor mounts do not need modifications. polyurethane bushings insulate from steel to steel contact. M.O.R.E. also offers replacement body mount parts.
