Upgrade Kit: Includes Engine Brackets and 1" Ultra-Flex Rubber Motor Mount Lifts

Whether you are replacing broken or worn-out parts or upgrading before a part breaks, this kit won't leave you with a sagging engine miles from civilization. The Brown Dog gives you his promise.   
  • All Steel Engine Brackets 
  • High Performance 1" Motor Mount Lifts 
  • All Grade 8 Hardware or 10.9 Metric Equivalent.

All Steel Engine Brackets features double-welded construction for extra strength. Bolt pattern identical to the original cast brackets. No engine block modification necessary. Fits 4.0L and 4.2L Jeep Chrysler engines. Will NOT fit 3.8L 6-cylinder engines. Brown Dog lipless design will not interfere with installation of 1" or 2" MMLs like the lips on the cast originals.

High Performance 1" Ultra-Flex Rubber Motor Mount Lifts (MMLs) feature all-steel, double-welded construction. These high-strength MMLs bolt into same location as the original motor mounts. Designed to stand up to the toughest trails Arizona can dish out. (Sorry Utah, we can't stand the cold.) The original mounts, designed for street driving, simply won't stand up to the torsional forces experienced offroad. Raises engine 1" at the stock cooling fan. Often used to counteract driveline angle issues created by suspension lifts or other modifications.

Ships with Grade 8 Hardware (or 10.9 metric equivalent) required to bolt engine brackets to existing engine block bolt pattern. Also includes new grade 8 thru-bolts, lock nuts and washers for securing brackets to motor mounts.
