Mountain Off Road JM700 - Manual

Thank you for purchasing M.O.R.E.™ motor mounts. They are designed to fit 1997-2006 Jeep® Wrangler vehi-
cles when installing a Generation III Chevy V-8 engines. Please refer to the photo above for the proper frame
location for the drivers side (DS) , and passengers side (PS). The block plates are the same for both sides. The
JM700 mounts are designed to off-set the engine slightly to the passengers side of the Jeep® frame for front
drive shaft clearance at the transmission. This means that you must use a transfer case with a drivers side front
drive shaft, i.e. NP231, NP241 Etc. These mounts will require the removal of the original frame mounts,
frame modifications for A/C & minor firewall trimming. Your Jeep Wrangler should also have at least a 1”
body lift and a minimum of a 4” suspension lift. Welding Required !
We have spent countless hours test fitting the JM700 mounts, on several chassis with several engine/
transmission combos and the JM700’s fit them all with slight, or no modifications. Remember, you are perform-
ing a “conversion” and it will require some effort to complete the project.
INSTALLATION GUIDELINES: The stock motor mounts that are welded on the Jeep® frame must be com-
pletely removed. Torch, grind or Plasma cut them from the frame rail. Be careful not to cut into the frame! Grind
any excess material from the frame so that the frame rails are smooth and have no ridges or slag remaining from
the stock mounts.
The frame side of the JM700 mounts are designed to fit the frame in the location that we feel is the ideal location.
These mounts are a weld on version so this location can be changed , that will be up to you to decide. Also the
block brackets have 2 sets of holes that allow the height to be changed by 1” , You decide on which set you
would like to use .
These mounts are designed to locate the engine in the proper location in relation to the firewall and radiator. We
insist that the engine dictate where the rest of the drive train is located. There is only one perfect location. That is
where we have located it. If installing a Chevy engine in your Jeep® for the first time, simply use the measure-
ments ( See pictures on page 2 ) to mount the JM700 motormounts to the frame by clamping (use some serious
“C” clamps, or you can “tack” weld them for now) the frame mounts to the frame, bolting the block plates to the
block, then install the engine and insert the 9/16” thru-bolts.
After the engine is bolted in place, then install the transmission and transfer case. When your conversion is com-
pleted and you are certain that everything is correct, then weld the motor mounts to the frame.
If you already have a Chevy engine converted into your Jeep®, and are replacing the conversion motor mounts
with M.O.R.E.™ BombProof™ mounts, the holes may not line-up with where your engine is located, due to the
infinite possibilities of engine locations. Don’t panic! These mounts should still work! Simply move them for-
ward or back to where your engine is located and weld the frame mounts to the frame.
