| The Brown Dog has experienced a couple busted stock motor mounts himself, on his own Jeep. This is why we engineered these replacement motor mounts for extreme strength. You'll find these mounts a serious upgrade from most other mounts, too. Bolts directly to original equipment brackets. Unlike most other high-performance motor mounts, these do not require trimming or grinding to fit. We've designed the left (driver side) mount to accommodate the lip found on the original driver-side bracket found on most XJ and MJ. You get full benefit of high performance motor mounts with bolt-in convenience. High Performance Design.
We use steel and feature double-weld joints to provide the most strength possible. And, just to make sure, we periodically pull a set of mounts off the shelf and put them through our 20-Ton Press Test. We have yet to see a Brown Dog Motor Mount or Motor Mount Lift with a structural failure ... even when used in competitive conditions. 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, we'll have them. Prefer Classic Polyurethane bushings for a sportier feel? We offer all motor mounts and motor mount lifts with either polyurethane or rubber to match your preference. Our Ultra-Flex Rubber bushings are completely interchangeable with the Classic Polyurethane bushings. All you need is a 10-ton press and our B2500-K (polyurethane) or BU2500-K (rubber) kit. Don't have a 10-ton press, we have a core program. Just ask. Not sure if you want to start with rubber or polyurethane? Click here.
Installation Notes - Mounts slide into original equipment engine brackets, in the identical position as the stock mounts. No trimming or grinding required.
- Engine remains in original stock position. If your old motor mounts were in bad condition, these mounts will return your engine to its stock position.
-
Carefully inspect engine bracket for any excess wear, especially cracks. The original brackets weren't designed to handle the strength of these high-performance motor mounts. If brackets show wear, order SU2572-0 which include both Motor Mounts, both Engine Brackets, and all new Grade 8 mounting hardware including new through bolts. However, the left (driver-side) motor mount is identical to the right side in the kit. This makes for a stronger all-around upgrade. If, after you have our "K" series mounts, you need brackets, be sure to call and discuss options. It's always in your best interest to order the brackets and mounts at once and save a few bucks along the way. -
Loosen transmission mount prior to raising engine. Failure to do this will result in excessive vibration after motor mount installation. We recommend replacing transmission mount when replacing motor mounts. However, at a minimum, loosen bolts and carefully inspect for wear. - Tighten through-bolts (bolt that goes through bracket arms and motor mount) snug. Do not over-tighten through-bolt lock nuts. Air tools should not be used here. Please remember, lock nuts are for one-time use only. If removed, they should be replaced, not re-used.
-
These motor mounts will bolt to frame-side brackets in the same position as your original mounts. These bolts should be tightened like most others on your Cherokee or Comanche. Nice and tight. -
If you have any questions during installation or believe a part will not fit, do NOT alter the part. Call Brown Dog, 866 401-3877 or contact us. We have extended support to assist with installation. Application Notes
