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 into 1980-1991 Jeep FSJ's.

1960's & 1970's era FSJ's, Gladiators, J-Trucks, Cherokees and Wagoneers should use our Novak #MMX-WG3 mounts.

Upgrade your Full Size Jeep with confidence using these heavy-duty engine mounts, specifically designed for a precise and secure installation of GM Generation III and Gen IV V8 engines—including popular LS and Vortec platforms. These mounts deliver exceptional strength, perfect alignment, and long-lasting durability for your classic Wagoneer, Cherokee, Grand Wagoneer, J10, or J20.

Easy, Reliable Installation:
These brackets are engineered for a true bolt-in fit, with clear step-by-step instructions to guide your swap. For maximum strength, we recommend adding a weld once mounted. Removal of original factory frame mounts for Tornado, Buick, or AMC engines is required before installation.

Engineered for Strength:
Constructed from robust 3/16" steel, these mounts are built to handle the power of even the most aggressive LS engines. Their thoughtful design and ample material ensure they won’t collapse under extreme use.

Optimized Placement & Clearance:
Engine position is pre-determined for the perfect fit in Full Size Jeeps, clearing steering systems and all key factory components—no modifications needed to your steering or frame.

Installers should note that these mounts are designed for best condition placement between the brake booster and the heater box of these FSJ series Jeeps. Test fit your engine with its coil packs before welding in the mounts permanently. Some of these FSJ's featured larger diameter brake boosters and the installer may need to choose a booster from a different year, or an aftermarket coil pack bracket to better accommodate these variations.

Superior Vibration Isolation:
Each set includes high-quality urethane isolators for the right balance of comfort and rigidity, plus 5/8" hardware for a solid, lasting connection. Replacement bushings are available for years of worry-free performance.

Customizable Finish:
Paint, powdercoat, or finish the brackets to your style for a truly custom, professional appearance.
