Brown Dog Left Super Bracket for 1991-2001 4.0L Cherokee XJ, 1991-1992 4.0L Comanche MJ.

Left (driver-side) Super Bracket features seven Grade 8 or M10.9 metric equivalent bolts - four more block attachment points than the original bracket. These additional bolts virtually eliminate shearing bolts or ripped engine bosses caused by the cumulative stress from years of potholes - or not so many years of offroad torsional forces. Often used as a repair for engine blocks with one to three damaged bosses or sheared bolts.

No engine block modification necessary. All seven threaded holes exist. Some are currently empty. A couple will be shared with other accessory brackets. We send everything needed. And our customers tell us our instructions and tips are extremely useful.

Have a sheared bolt or a torn boss? Don't sweat it. With this bracket you'll still have more bolts securing your engine in place than you originally did. In fact, we never suggest pulling the engine to remove sheared bolts. It's just uneeded work. And who wants that!

Compact design accommodates both original-style manifold and aftermarket headers. According to header manufacturer's warranty staff, one of the leading causes of cracked headers is worn motor mounts. (Of course, worn or missing exhaust hangars/brackets also can cause cracks.) This Brown Dog bracket design works with your original manifold or Banks, Borla, Pace Setter, Edelbrock, and many other common aftermarket headers. The bracket and mounts, when used together, offer a little more room in the exhaust area to assure no conflict. So if you're replacing your manifold, consider replacing the brackets and mounts, too. 

Change mounts and brackets all at the same time. Save a few bucks. And never have to do it again. While this bracket can be used with original-style motor mounts, when converting to Brown Dog engine brackets, we strongly recommend upgrading to Brown Dog high-performance motor mounts at the same time. The original mounts, designed for street driving, simply won't stand up to the torsional forces experienced offroad...or all-to-frequent pot hole in today's streets. To save you some bucks, we developed kits, including both motor mounts and brackets, for a significant discount compared to purchasing everything individually.

  • S2572-0HRX, includes a pair of Super Engine Brackets and Classic Polyurethane Motor Mounts.

  • SU2572-0HRX, includes a pair of Super Engine Brackets and Ultra-Flex Rubber Motor Mounts.

The Brown Dog ships all new Grade 8 hardware (or metric equivalent) required to bolt brackets to seven attach points in the existing engine block. Grade 8 through-bolts, prevaling-torque locknuts and washers are also included for securing brackets to motor mounts.
