Features
Ease of Installation
These mounts are weld-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. Engineered using advanced CAD modeling and real world testing, these mounts have shown to handle even the wildest V8.
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.
Adjustability
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.
Engine Mount Finish
All parts except the frame brackets are zinc coated for resistance against corrosion. As the frame brackets are welded to the frame, any finish on the frame side brackets as well as the frame would be burned. The welded channels will need to be finished but you may enamel, powder coat or otherwise finish the bracketry and adjacent frame area to your own style.

Applications & Compatibility
Engines
These mounts will work with nearly all major Windsor engines, including the 289, 302, 5.0L and the 351/5.7L.

Installation Requirements
Old Mount Removal
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:
- Left-right offset location is similar to factory at ~1-1/4" to the driver's side
- Avoid installing the engine too low (axle clearance and other issues)
- Avoid installing the engine too high (transmission tunnel interference, etc.)
- Set your engine to 4-7 degrees of tilt rearwards, like the factory engine & powertrain
- When mocking up your engine installation location, pay special attention to radiator and fan clearance.
- Firewall modifications are not expected.

Driveshafts
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.
