GM Generation III & IV V8 Engine Mounts


YJ Wrangler Jeeps

Novak's weld-in engine mounts for the Jeep YJ Wrangler provide immense strength and a precise GM Vortec & LS V8 engine installation.

Product & Features


Ease of Installation

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. 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.

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 

As the mounts are 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.


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


These mounts fit all 1987-1995 Jeep YJ Wranglers.


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

Installation Requirements

Removal of the factory frame mounts for both 2.5L I4 and 258 / 4.0L I6 engine Wranglers is required. This is best done with a separating disc, plasma cutter, torch, or reciprocating saw, followed up by a grinder or flap-wheel.


We have predetermined engine placement for the installer. There is a very fine window in which the GM Gen. III & 4 V8 can properly fit into the YJ Jeep, and we've done this design legwork already.
