  • Super Strong Engine Brackets - 7 Bolts, Left; 8 Bolts, Right
  • High Performance Ultra-Flex Rubber Motor Mounts - Stock Height
  • 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 engine block attachment stress loads. Left bracket features 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. Utilizes existing 4.0L or 4.2L Jeep engine block bolt pattern.


High Performance Ultra-Flex Rubber Motor Mounts feature all-steel, double-welded construction. Stock-height, these are high-strength replacements for the originals. 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 for a fair price. The original mounts, designed for street driving, simply won't stand up to the torsional stress experienced offroad.  Featuring Ultra-Flex Rubber bushings, these Motor Mounts will dampen some drive line vibration. Want a sportier feel for your rig? Select Classic Polyurethane Motor Mounts in the S2572-0 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. 

Looking for Motor Mount Lifts? Super Kits, SU2572-1 or SU2572-2, include 1" or 2" Ultra-Flex Rubber Motor Mount Lifts (MMLs) with the Super Engine Brackets. MMLs are often used to correct driveline angle problems. Super Engine Brackets feature unique lipless bracket design will not interfere with installation of 1" or 2" MMLs. 

Application Notes:
Brackets utilize existing bolt pattern found on 4.0L and 4.2L (6-cylinder) Jeep engines.
