Change entire engine mount system at the same time and never have to do it again. 

  • Super Brackets with more engine block attachment points
  • High Performance 1" Motor Mount Lifts 
  • All Grade 8 Hardware or 10.9 Metric Equivalent.
Super Brackets virtually eliminate offroad torsional forces snapping bolts or ripping the bracket from the case. Featuring more attach points than the original brackets, the design spreads engine block attachment stress loads. Left bracket features up to seven bolts, four more than the original. Right bracket features eight bolts, five more than the original. Double-welded, all-steel construction for extra strength. No engine block modification necessary. Lipless design eases installation of 1" Motor Mount Lifts. Bracket bolt holes line up with existing 4.0L or 4.2L Jeep engine block bolt pattern.
High Performance Classic Polyurethane 1" Motor Mount Lifts (MML) raise engine 1" at stock cooling fan. Brown Dog MML feature all-steel, double-welded construction. These high-strength MML bolt into the same location as the original Jeep motor mounts sold on the vehicle. Designed to stand up to the toughest trails Arizona can dish out. (Sorry Utah, we can't stand the cold.) When compared to the originals and most others, these are a substantial upgrade. The original mounts, designed for street driving, simply won't stand up to the torsional forces experienced offroad.  Prefer Ultra-Flex Rubber to absorb drive line vibration? Check out Super Kit SU2572-1. Not sure whether to select Classic Polyurethane or Ultra-Flex Rubber? Compare here.

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.
