allow for the additional engine weight.
a 1997-2006 4 cylinder steering bracket, Part# 52058855AB. If your replacing a 6
cylinder, you will need this Jeep part number or our 713093P.

This motor mount is designed to work with

New Mount Installation:

Refer to the owner’s manual for the stock engine removal. Once the stock engine is removed, cut the original motor
mounts from the frame. Also remove the steering pillow block bracket and discard. Clean all remnants of weld so that the
frame is smooth. Make sure that the frame surface for the mounts is bare metal so that there are no contaminants in the
weld area. The TJ frame has a small hole on both sides that originally held the brake lines. By removing the brake line
mounting bracket you expose the hole that is used for our fixture bracket. Take the fixture bracket and lay it on the frame
using the 1/4” bolt as a dowel. Lay the new motor mount frame bracket over the frame and slide it towards the front until

it hits the fixture. Clamp or tack weld the mount to the frame. Do not weld the fixture
bracket to the frame. It is only used to locate the new motor mount. Repeat the
clamping and/or welding procedure for the other side. When both sides are in a fixed
position, use a tape measure and check from the center of the passenger side hole to the
center of the driver’s slot. You should come close to 19.5”. It is also a good idea to
check to see if both of the new frame mounts are located the same distance back on the
frame. Next, verify that the steering pillow block fits to our mount, (6 cylinder Jeeps
must purchase the 4 cylinder pillow block listed above) without any interference. When
the mounts have been correctly positioned, weld them in place and paint.

SPECIAL NOTE: The components packaged in this kit have been assembled and machined for specific type of conversions. Modifications to any of the
components will void any possible warranty or return privileges. If you do not fully understand modifications or changes that will be required to complete your conversion,

CHEVY 4.3L V-6 ENGINE

TJ WRANGLER MOTOR MOUNTS

Engine Installation:

* For ease of installation, leave the engine motor mount brackets off until the engine is in place.
* The new 4.3L engine is slightly different that the original one. Firewall modifications may be necessary.
* A trial run is highly recommended.
* The engine and transmission should be bolted together for an easier installation.

Using an approved engine
hoist, lower the engine into
the compartment. Pay atten­tion to the exhaust manifolds
and the radiator (removing
the radiator is a good idea).
The engine may not slide fully
into the compartment due to
firewall interferences (check
the clearance on both the
driver’s and passenger side

around the engine heads
and above both of the exhaust manifolds/headers). Mark these spots
with a pen, remove engine, and clearance the firewall accordingly. Lower
the engine back in and check the clearance. Using the supplied hard­ware, attach the engine plates to the block. When secured, guide the
upper mount portions through the frame brackets and bolt them into
place. Take the four large 1/4” spacers (2 per side) and trial fit them to
get a comfortable front-to-rear engine placement. These mounts have
up to 1/2” movement front-to-rear to account for any differences in
frame locations and to “fine tune” engine placement. Use the 1/2” bolts
and nylon nuts to secure the engine to the frame. Bolt the steering pillow
block assembly to the mount. Take a quick look around the engine and
steering to make sure there are no clearance issues. You should have just
enough room to fit your hand between the engine and firewall/frame.

Gauge Wiring:

The Chevy V-6 and the Jeep systems do not “speak the same language”. In our installations, we retained the stock Jeep
computer as well as installed the new 4.3L computer. We retained the stock Jeep sending units and attached them to the
GM block (oil pressure, temperature, and fuel level). All of them work fine except the tachometer. An aftermarket
tachometer would be the easiest option at this point, or a “black box” to modify the signal. Since you are using the stock
sending units, the Jeep computer thinks that the original engine is still sending information. The Jeep service manual
identifies the color coded wires in the harness; we retained the ones for the gauges and the other leads that are not used
