  • All Grade 8 or M10.9 Hardware.

Super Engine 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 the stress load on engine block bolts and thread bosses.  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 Ultra-Flex Rubber 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.) The original mounts, designed for street driving, simply won't stand up to the torsional forces experienced offroad.  When compared to most others, these are a substantial upgrade. Featuring Ultra-Flex Rubber bushings, these MML will dampen some drive line vibration. Want a sportier feel for your rig? Select Classic Polyurthane Motor Mount Lifts featured in the S2572-1 Super Kit instead. Not sure which is better for you? 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.
