INSTALLATION INSTRUCTIONS for JM25840L BombProof™ MOTOR MOUNTS

You may need to grind clearance in this area to

allow the BombProof™ mount to fit into the factory “fork”. More common on YJ’s.

Please read and understand all instructions before beginning the installation of these motor mounts. Please read the terms and policies on the back of these instructions.

The JM25840L motor mounts are a one inch lifted version of our standard motor mounts. They are designed to fit the following Jeep® vehicles: 1987-1995 YJ Wranglers equipped with 6-cylinder engines (4.0L or 4.2L), 19972006 Jeep® TJ & LJ Wranglers equipped with 4.0L engines. ALL Jeep® VEHICLES USING THESE MOUNTS MUST HAVE A ONE INCH BODY LIFT INSTALLED!!! The design is such that you will notice more vibration

then the stock rubber motor mounts, mostly at idle. However, the fact that the engine will be “clamped” in

place far better then the stock mounts is worth the slight increase in vibration.

STEP 1: With the Jeep® on flat level ground, apply the parking brake, block the tires so it cannot move.

Put the transmission in neutral. Using a jack, place a block of wood between the jack and the oil pan. Apply a slight amount of pressure on the oil pan. Remove the bolts holding the fan shroud to the radiator. (The shroud should have been “lowered” one inch with the body lift kit. You will re-attach it to the “stock” location after the in- stallation of the lifted motor mounts.

STEP 2: Remove the drivers side stock motor mount. Save the hardware that you removed because it

will be re-used. Install the BombProof™ motor mount in it’s place. On some models of Jeep® vehicles we have found that the factory does not machine the block mounting “fork” deep enough for the BombProof™ mount to fit into it. This means that you must grind the “fork” until it does fit! See above photo. Also, on some Wrangler vehi-

cles, we have found that when lifting the engine, the engine mounting fork can contact the frame of the Jeep®. If this is the case on your vehicle, modifications to the frame and or fork may have to occur. Use common sense when performing this modification. Do not tighten any of the nuts or bolts at this time. If your vehicle has a aftermarket suspension lift kit that uses spacers between the skid plate and frame to lower the transfer case, this can cause the motor mounts to be slightly out of alignment. If you have trouble lining-up the thru-bolt, it may be necessary to temporarily un-bolt the transmission mount from the skid plate and raise the transmission up slightly until the thru-bolt lines up.

STEP 3: Remove the stock motor mount from the passenger side of the engine. Install the BombProof™

motor mount in it’s place. On some models of Jeep® vehicles we have found that the factory does not machine the block mounting “fork” deep enough for the BombProof™ mount to fit into it. This means that you must grind the “fork” until it does fit! See above photo. Also, on some Wrangler vehicles, we have found that when lifting the

engine, the engine mounting fork can contact the frame of the Jeep®. If this is the case on your vehicle, modifications to the frame and or fork may have to occur. Use common sense when performing this modification. Re -use the stock hardware. Do not tighten the nuts or bolts yet. If you had un-bolted the transmission mount from the skid plate in step 2, you can now lower it back into place and tighten the bolts that you removed.

STEP 4: Tighten the bolts and nuts on the bottom of the BombProof™ motor mounts to factory specs.

Tighten the thru-bolts on the engine mounting “fork” to factory specs. Remove the floor jack. Re -attach the fan shroud to the factory holes in the mounting flange on the radiator. This should keep the fan “centered” in the

shroud. Check all of the hardware for proper torque specs after 50 miles and every off -road use. Thank you for

purchasing your BombProof™ motor mounts from M.O.R.E.™.

TERMS-POLICIES:

FIT and TOLERANCES: These Motor Mounts are the results of countless hours of research, testing, fitting and refining. Jeep® frames have

a wide tolerance on bolt hole centers from frame to frame. This is why M.O.R.E.™ has installed “slots” in which to mount them. In addition to the factory tolerances, most people install other then factory equipment such as suspension lift kits, skid plates, different transfer cases etc. M.O.R.E.™ has done the best job we can to insure that our parts fit with all of the possibilities. However, you may find it necessary to grind, elongate, bend, or force these parts to fit on your rig. Please use common sense when installing these parts and let us know how we can improve them.
