Brown Dog Super Engine Brackets for 1991-1999 Jeep Wrangler YJ & TJ 4.0L I-6 (Pair).

This pair of Super Engine Brackets features more attachment points than the original brackets to spread the stresses on engine block and bolts. Left bracket features seven bolts, four more than the original. Right bracket features eight bolts, five more than the original. These bolt directly to existing holes. No engine block modification necessary. Double-welded, all-steel construction for extra strength. Sleek design doesn't interfere with aftermarket headers, keeping this option available down the road.

Don't get caught miles from civilization with a sagging engine, or worse yet, with an engine that's let loose from the frame pushing the cooling fan into the radiator. Trust us and many other Jeep owners, it's not a fun way to get away from it all!

Often used by collision repair professionals to save an engine block with sheared bolts and/or broken bosses from the scrap heap, even with two or three bosses deemed unusable, your engine is still attached with more bolts than when new.

While these can be used with original strap-style motor mounts, when converting to these brackets, we strongly recommend upgrading to Brown Dog high-performance motor mounts or motor mount lifts. The original mounts, designed for street driving, simply won't stand up to the torsional forces experienced offroad. Our unique lipless bracket design will not interfere with installation of 1", 1.5", or 2" MMLs.


Change mounts and brackets all at the same time and never have to do it again. Select one of the following kits and get both mounts and brackets.
  • Super Kit, S2572-0HW, includes Super Brackets & High-Performance Classic Polyurethane Motor Mounts.
  • Super Kit, SU2572-0HW, includes Super Brackets & High-Performance Ultra-Flex Rubber Motor Mounts.
  • Super Kits, S2572-1HW, S2572-1.5HW, or S2572-2HW, include 1", 1.5", or 2" High-Performance Classic Polyurethane MML & Super Engine Brackets.
  • Super Kits, SU2572-1HW, SU2572-1.5HW or SU2572-2HW, include 1", 1.5", or 2" High-Performance Ultra-Flex Rubber MML & Super Engine Brackets.
Installation Hardware Included.
The Brown Dog ships all new Grade 8 hardware (or metric equivalent) required to bolt both brackets to all attach points in the existing engine block. Grade 8 or M10.9 equivalent through-bolts, locknuts and washers are also included for securing brackets to motor mounts or motor mount lifts. 
Application Notes:
Utilizes existing bolt pattern found on 4.0L (inline 6 cylinder) Jeep engines originally sold in:
  • Wrangler YJ, 4.0L I-6, 1991-1995
  • Wrangler TJ, 4.0L I-6, 1997-1999
Caution: Not all I-6 have the same bolt pattern. If you're not sure your engine is the original, call or email the engine block casting number. (Located under fron freeze plug.)

Installation Notes
  • In preparation for installation, we suggest using brake fluid cleaner or PB Blaster to clean out the additional engine block thread bosses.  
  • A copy of the installation instructions showing which holes take which bolts will be included with your bracket. We can also email it ahead of time when requested.
