Planning a Gen V LS swap in your Full Size Jeep? Novak’s MMSJ-G5 engine mount kit takes the guesswork out of positioning, strength, and clearance. Built specifically for 1980–1991 FSJs, these mounts are designed to make installing a GM Generation V (Gen 5) small block V8 both precise and reliable.

Each kit includes frame-side brackets, engine block plates, upper and lower urethane isolators, and Grade 8 hardware. The mounts are CNC-formed from 3/16" thick steel and engineered to handle the torque of even high-performance V8s without flex or fatigue. Novak’s compact layout maintains full clearance around factory components including steering boxes, brake boosters, and heater boxes.

Installation is bolt-in, but for maximum strength Novak recommends adding a perimeter weld after positioning. You’ll need to remove the original frame mounts from any Tornado, Buick, or AMC engine configuration before starting.

Fits:

  • 1980-1983 Wagoneer
  • 1984-1991 Grand Wagoneer
    1980-1983 Cherokee
  • 1980-1988 J-Series Truck

What’s Included:

  • Frame platform brackets
  • Upper and lower urethane bushings
  • Engine block plates
  • Heavy-duty mounting hardware
  • Detailed installation instructions

Why Choose Novak’s MMSJ-G5 Mounts:

  • Pre-set engine position for proper fit in FSJ chassis
  • Bolt-in ready with weld-reinforcement option
  • Compatible with Gen V LS engines (L83, L86, etc.)
  • Maintains factory steering clearance
  • Designed, tested, and built specifically for 1980–1991 FSJ Jeeps
  • Durable urethane isolators strike the ideal balance between vibration control and strength
  • Replacement bushings available down the road

You can finish the mounts in your preferred style—paint, powdercoat, or leave them raw to match your build.
