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 and engine block 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 Block Brackets come into play. The block brackets are designed to catch additional holes in your engine block. By spreading the massive engine torque through out the additional bolts (instead of just 3 factory bolts) these block brackets will save you expensive engine damage not to mention being out in the back woods broke down. These block brackets are to be used in addition with the factory motor mounts or our "bomb proof" motor mounts JM--- depending on your model of Jeep.
They will fit stock exhaust manifolds, but may require modification to clearance for some headers.
Fits: 1991-1995 Jeep YJs with 4.0L engines.
