for

1980-1991 FSJ, Full-Size Wagoneer, J-Truck & Cherokee Jeeps

Novak's weld-in engine mounts for the 1980-1991 Jeep FSJ Trucks provide immense strength and a precise GM Generation III+ V8 engine installation. 1960's & 1970's era FSJ's, Gladiators, J-Trucks, Cherokees and Wagoneers should use Novak's #MMX-WG3 mounts.

Ease of Installation

These mounts are bolt-in style and detailed instructions will guide to an ideal installation. We do recommend a weld be placed on these mounts on the top lip (and sides too if you would like) for the best strength achievable.

Strength

The Novak mounts feature thick 3/16” laser cut and CNC bent steel construction. Engineered using a welded box design geometry to provide maximum strength and assure that they will survive even the wildest V8's.

Vibration Isolation

Each mount kit comes with our steel reinforced 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 steering shaft with its pillow block and the recommended exhaust headers below.

Engine Mount Finish 

As the mounts are usually also welded to the frame, any finish on the frame side brackets as well as the frame would be burned. You may enamel, powder coat, or otherwise finish the bracketry and adjacent frame area to your own style. Engine plates are coated in a rust resistant finish but may also be painted.

Contents

Each mount set contains left and right frame mounts, two sets of urethane bushings, two engine plates, along with the necessary installation hardware and instructions.

Applications & Compatibility

Jeeps

These mounts fit all 1980-1991 FSJ, Full-Size Wagoneer, J-Truck & Cherokee Jeeps.

Engines

These mounts will fit the GM Gen III & IV LS/Vortec V8 engines.

Installation Requirements

Unbolting and removal of the factory frame mounts for factory AMC engines is required.

Placement 

We have predetermined engine placement for the installer. There is a very fine window in which the GM Gen. III & IV V8 can properly fit into a FSJ Jeep, and we've done this design legwork already. The mounts will offset the engine the recommended amount to the passenger side for optimal brake booster and heater unit clearance.
