M.O.R.E. Bomb Proof Motor Mount Kit - Jeep CJ 1972-1986 AMC 4.2L / Pre-99 4.0L
Rock crawling puts loads on a CJ that the factory never planned for. Low gears, lockers and big tires multiply torque, and the stock motor mounts can tear apart surprisingly fast. This M.O.R.E. Bomb Proof kit swaps them for steel mounts with black polyurethane bushings that keep the AMC six held tight.
Fitment is specific, so read this part carefully:
- 1976-1986 Jeep CJ-5, CJ-6, CJ-7 and CJ-8 with the AMC 6-cylinder (4.2L or a pre-1999 4.0L): direct fit
- 1972-1975 Jeep CJ-5 and CJ-6: fits with slight frame modification
- 4.0L engines need 4.2L block plates to work with this kit
The mounts bolt into the stock frame and engine holes, and most installs need no modification. If you are swapping in a 4.0L, budget for the 4.2L block plates. Pick zinc plating for corrosion protection, or the no-plating version if you want to save a little and paint them yourself. M.O.R.E. (Mountain Off-Road Enterprises) has been building Jeep parts in Delta, Colorado since 1978, when Chris Overacker started the company in his home garage. Parts are designed in 3D CAD, laser cut and welded in-house in the USA.
M.O.R.E. backs its parts with the RockProof Lifetime Warranty for the original retail purchaser, for as long as they own the vehicle, against product failure. Rubber, urethane and the finish are treated as wear items and are not covered, and neither is labor or shipping.
