K2572-0, Upgrade Kit, Classic Polyurethane

Upgrade Kit: Includes Brackets and Motor Mounts
Whether you are replacing broken or worn-out parts or upgrading before a part breaks, this kit won't leave you with a sagging engine miles from civilization. The Brown Dog gives you his promise.  

• All Steel Engine Brackets 
• High Performance Classic Polyurethane Motor Mounts - Stock Height
• All Grade 8 Hardware or 10.9 Metric Equivalent.

All Steel Engine Brackets feature double-welded construction for extra strength. Identical bolt pattern to the original cast brackets. No engine block modification necessary. If you decide to install 1" or 2" Motor Mount Lifts in the future, these lipless brackets will not interfere like the lips on some cast original Jeep brackets.

High Performance 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.) The original mounts, designed for street driving, simply won't stand up to the torsional forces experienced offroad.  Maintains stock engine height at the cooling fan.

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? Upgrade kits, K2572-1 or K2572-2, include 1" or 2" Motor Mount Lifts (MMLs) with the all-steel engine brackets. Unique lipless bracket design will not interfere with installation of 1" or 2" MMLs.
