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.  

  • Pair All-Steel Header Engine Brackets (B2569-PH)
  • Pair High Performance Ultra-Flex Rubber Motor Mount Lifts (CU2569-1)
  • Right Mount Support Cradle (CR2569)
  • All Grade 8 Hardware or 10.9 Metric Equivalent

All Steel Engine Brackets feature double-welded construction for extra strength. The cast aluminum engine brackets found on many 4 cylinder Jeeps are prone to failure under the torsional stresses associated with even "easy" offroad trails. Once you've seen a busted cast bracket, you'll know why we continue to use these for our own Wrangler. Identical bolt pattern to the original cast aluminum engine brackets. No engine block modification necessary. Fits 2.5L Jeep engines with aftermarket headers. If you decide to switch from Motor Mounts to Motor Mount Lifts in the future, the lipless design of these brackets will not interfere with installation.

High Performance Motor Mount Lifts feature all-steel, double-welded construction. These high-strength Motor Mount Lifts bolt into the same locations as the original motor mounts. 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. Motor Mount Lifts raise engine 1" at the stock cooling fan.Commonly used to correct driveline angles from a suspension lift or used with a tummy tuck.

Featuring Ultra-Flex Rubber Bushings.

These Brown Dog motor mounts feature our proprietary Ultra-Flex Rubber bushings designed to dampen drive-train vibration. If this is your daily driver, you may find these bushings well worth the extra money. Should you ever need to replace the bushings, well have them. Prefer Classic Polyurethane bushings? We offer all motor mounts and motor mount lifts with either polyurethane or rubber to match your preference.  Not sure which is for you? Click here.

Replacement Cradle Supports Right Mount designed to withstand severe offroad stresses. Constructed entirely of steel and grade 8 (or metric equivalent) studs, cradle bolts directly to the passenger side pylon, holding motor mounts in place. The original stamped cradle is very difficult to find, even in salvage yards. Due to it's location between the motor mount and the pylon, it is difficult to see if original cradle is broken. Yet, because it's especially prone to the torsional forces experienced offroad, numerous 2.5L Jeep owners have found their original cradle broken into multiple pieces.

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. 

Application Notes:
This kit replaces everything from the pylon to the block, both left/driver and right/passenger sides. Engine brackets utilize existing bolt pattern found on 2.5L (4 cylinder) Jeep engines. Motor mount lifts (left/driver side) and support cradle (right/passenger side) bolt to pylon in same position, using same bolt holes as original configuration.  Right motor mount bolts to support cradle. Kit includes new Grade 8 through-bolts, washers and lock nuts for securing new motor mounts to new engine brackets.
