Novak engine mounts have been among our popular flagship products for decades. This classic #MM Series mounts offer a lot of installation freedom.
Note that these legacy mounts have a newer #MMX option as well. We've retained these because they are still in good demand. See Image Gallery at the bottom of this page to see this style of mount and how they work.
These mounts are weld-in style and detailed instructions will guide to an ideal installation.
The Novak mounts feature thick 3/16” laser cut and CNC bent steel construction. After years of real world testing, these mounts have shown to handle even the wildest V8.
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.
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.
The design on these mounts allows outstanding placement freedom in most any vehicle that meets the width requirements and has parallel frame channels. They have a large adjustment range for placement in the vertical, left-right offset, and longitudinal directions.
All parts are ready to accept the coating of your choice which allows matching the brackets and adjacent frame area in paint, powder coat, or other finish.

These mounts will work with nearly all major Windsor engines, including the 289, 302, 5.0L, and the 351/5.7L.
Unbolting or cutting is required to remove the factory frame mounts for factory Jeep engines. This process will vary from model to model. you will want to completely remove and smooth the surface of your frame rails for a nice fitment of the new engine mount channels to your frame.
Engine placement in these Jeeps should consider the following points:
Driveshaft length changes may be required. Because of their narrower and but longer form, Ford engines can install at nearly the same location as AMC engines (using the back face of the block as the datum point) for exhaust clearance, firewall access, etc.
Some installers, concerned about the expense of new or modified driveshafts, attempt to let the existing driveshafts dictate engine, transmission and transfer case location, often to the detriment of the project. Our recommendation is to prioritize the correct position of drivetrain components over saving a few dollars which is usually regretted in the long run with compromised positioning.
Jeeps that require extensive travel or specialty-built driveshafts have this option available through several fabricators across the nation. These are normally specified after placement of the new transmission and measured at vehicle ride height. As the rear driveline gets shorter, it is often advantageous to us a Double Cardan or “CV style” rear shaft with the correct geometry at the axle to minimize vibrations and possible binding.
Use of factory axles is completely acceptable with this conversion. Axle upgrades are not necessary, but they may be chosen for reasons external to this transmission upgrade.
The provided frame brackets can be configured in the lower hole set and cupping for lower engine locations...
... or they can be placed in the higher hole-set and platforming for higher engine location.
