Chevrolet Generation I & II Small Block V8 Engine Mounts
for
XJ Cherokee & MJ Comanche Jeeps

Ease of Installation
These mounts are bolt-in style and detailed instructions will guide to an ideal installation.
Strength
The Novak mounts feature thick 3/16" laser cut and CNC bent steel construction. The formed frame brackets hug the Jeep unibody frame, creating a plate steel overlay that will add rigidity to this most important part of the Jeep frame. Generous welds, smart geometry and multiple attachment points make for a robust installation.
Vibration Isolation
Each mount kit comes with our high-grade urethane isolators that are specified for that ideal balance of isolation and firmness with the power of modern engines. Substantial 5/8" through bolts capture the assembly. Replacement bushing sets are available below should replacement ever be needed.
Compactness
Geometry of the mounts is compact to provide clearance for all stock components including the steering shaft with its pillow block and the recommended exhaust headers below.
Engine Mount Finish
The engine mounts are in a rust resistant black zinc plated finish but may also be painted.

Installation Requirements
Unbolting and removal of the factory frame mounts for factory engines is required. Steering remains as per factory. A lift kit and bump stops may be required to correct for sagging factory springs and clearance requirements for your GM oil pan. This and many other important details are covered in our provided instructions.
Engine Placement
These mounts are a purely bolt-in design. Once the old mounts are removed and the engine bay is cleared and prepped, the #MMXJ3 mounts can be installed rapidly. All fastening hardware is provided. The installer will need to have a 7/16"-14 tap to thread a blank body insert.
