Brown Dog Pair Super Engine Brackets for 1987-1990 Jeep Wrangler YJ 4.2L I-6

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 four bolts, one more than the original. No engine block modification necessary. Double-welded, all-steel construction for extra strength. While designed to prevent sheared bolts and.or broken thread bosses on the block, many professional collision repairs are done with these brackets after the original bracket has sheared bolts or broken a boss or two. This design has saved many engines from the scrap heap.

Hand-crafted in the USA of 1/4" USA steel plate.
Brown Dog brackets are made of 1/4" USA steel plate. While others use 3/16" steel, we know the 1/4" USA steel plate is stronger. The parts are carefully laser cut and drilled. Then double-checked against our drawings. Then we double-weld the bracket assembly for even more strength. Next your bracket is triple-checked for fit. After blasting to white, the brackets are finishd and baked in our ovens. This proprietary finish has become the beacon of quality sought by Jeep owners around the world. It's the sign of a quality performance build. We team our Super Brackets with all USA Grade 8 and M10.9 hardware needed for installation. This includes throguh bolts, prevailint-torque locknuts, and washers for securing brackets to motor mounts or motor mount lifts. Finally, it's all carefully wrapped and packaged with a sticker and instruction tips.  


Easier installation. 24/7 tech assistance.
No need for special tools to reach into small holes for bolt installation. Never a need to pull the engine. Installation is straight forward when you take your time and carefully follow installation tips. We'll email the preparation and installation tips upon request. Our phones are forwarded afterhours and weekends for technical assistance. We've talked many customers who have never done this type of work through the process. You can do it. We promise we'll help.


Save money. Save time. Upgrade to our Super Kit.
Upgrade to our high-performance mounts or motor mount lifts and our Super Brackets all at the same time. And never have to worry about your engine mount system again. Which kit? It's up to you. Considerations include how you drive, where you drive, how your Wrangler is configured, and your plans for the future. All Super Kits include brackets for both sides, a pair of high-performance motor mounts or motor mount lifts, and all installation hardware.


Application Notes:
Utilizes existing bolt pattern found on 4.2L (inline 6 cylinder) Jeep engines originally sold with 1987-1990 Wrangler YJ. These engines have a mechanical fuel pump, thus only four holes are available for use on the passenger side. Even if your engine has been converted to a fuel injection system, the mechanical fuil pump may still be in place to cover the hole.
