4.0 Motor Mount Kit
This kit includes both motor mounts and motor mount brackets. They are bolt-in replacements for Jeep XJ and MJ 4.0-Liter engines.
The motor mounts are made from 1/4" high-tensile 100,000 psi laser-cut and CNC-formed steel plate for unmatched strength to replace the constant failing factory motor mounts. We use genuine Clevite rubber bushings. Steel is guaranteed for life.
The XJ motor mount brackets replace the weak factory brackets that are prone to cracking and breaking on the trail. It only takes one failure to leave you stranded with your motor crashed into your radiator. These brackets are 3/16" thick grabbing 7 and 8 holes as opposed to the weak 3-bolt mounts. Two parts formed per unit allowing for less weld deformation and edge weaknesses. These are designed to withstand high horsepower and racing applications, but great for on and offroad applications on all levels. You won't ever have to worry about your mounts again!
All engine mounts use a proprietary clevite rubber bushing that absorbs energy, but does not allow the engine to move around freely like an OE mount. These mounts are designed for heavy abuse and off-road applications. These mounts can allow for more vibrations to be felt in the vehicle. If you drive your Jeep and like that it feels like your moms minivan do not buy these mounts. We do not refund installed parts because you don't like how they feel. If you want more torque transfer, more power to the ground, unbeatable reliability and strength then these are the mounts for you. If you want to maintain the original floppy soft feel of factory mounts THEN DO NOT BUY THESE!
