BombProof Motor Mount Kit' JM700 Generation III V-8 and V-61997-2006 Jeep Wrangler 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 BombProof 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 BombProof motor mounts do not need modifications. Black polyurethane bushings insulate from steel to steel contact.
