Mountain Off-Road JM400 BombProof Motor Mounts in Bare Steel for 87-95 Jeep Wrangler YJ with GM V8

Quadratec Part #: 12590.0724
Mountain Off-Road Part #: JM400
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 kits products come into play. The factory motor mounts must be removed from the frame to install these mounts. They are indexed to factory holes in the frame so line-up is a breeze. These mounts must be welded to the frame, so they come bare steel, no paint. They are set-up to offset the engine to the passenger side 1 inch, so a T-case with a drivers side front drive shaft must be installed (231 or 241).
