Features
- This Cummins 4BT Engine Mount Kit Has Been Specifically Designed For The Jeep Wrangler CJ Generation
- These Mounts Have Been Developed Over Years Of Experience And Testing And Will Last The Lifetime Of Your Jeep, Or Your Money Back
- The Most Important Design Aspect Of Our Mounts Is Correct Isolator Location
- The Cummins 4BT Has Earned The Name "The Paint Shaker" Because Of Incorrect Engine Swaps That Lead To Uncomfortable Vibrations
- Many Try Liquid Filled Hydraulic Isolators To Mitigate Vibrations And Are Usually Disappointed
- The Best Design Strategy For Controlling Engine Vibration Is Based On Three Guidelines
- Isolators Are Positioned Above The Crankshaft Centerline
- Isolators Are Mounted On A 45 Degree Angle
- Isolators Are Centered On The Engine Front To Back To Evenly Distribute Weight
- Engine Mounts Are The Only On The Market That Meet All These Guidelines For A Smooth Running Engine Without Expensive Isolators
- Isolators Can Be Purchased At Local Auto Parts Stores
- Using The 3 x 2 Mounting Bosses On The Lower Front Of The Engine Alone Is Not Recommended
- Front Engine Bosses Should Not Be Used Solely Because They Cause Uncomfortable Vibrations And Stress The Bellhousing
- Additional Mounts Must Be Used At The Bellhousing If Front Engine Bosses Are Used
- Mounts Will Not Clear Later 4BT Vacuum Pump/Power Steering Pump But Will Clear Earlier "Pancake" Style Pumps
- Hydroboost Brakes Are Recommended For 4BT Engine Conversions
- HVAC Controls Can Be Operated By A Remote Electric Vacuum Pump
- Mounts Provide Ample Clearance For Most Starters But Slight Trimming May Be Required
- At Least A One Inch Body Lift Is Usually Required To Clear The Transmission Tunnel
- Fits 76-86 Jeep CJ7
Description
Precision Engine Mounts. The Cummins 4BT Conversion Engine Mounts are engineered specifically for Jeep Wrangler CJ applications to ensure reliable and vibration-free operation. These mounts address common issues of excessive vibration commonly associated with Cummins 4BT swaps by prioritizing correct isolator positioning, providing improved driving comfort and component longevity.
Construction and Appearance. These mounts are crafted using durable materials designed to withstand the rigors of off-road and on-road use, featuring carefully positioned isolators above the crankshaft centerline at a 45-degree angle. The finish is designed for longevity and corrosion resistance, with functional and robust aesthetics tailored for the engine bay.
Installation. Installation requires moderate mechanical skills and typically does not involve drilling, although slight body modifications, such as a 1-inch body lift, may be necessary for fitment clearance. Some starter clearance adjustments might also be required during installation.
Warranty. A comprehensive 3-year warranty from the date of purchase ensures durability and confidence in performance.
Application. These mounts are designed specifically to fit 76-86 Jeep CJ7 models, offering precise fitment with considerations for pump clearance and recommended brake conversions.
