With regard to XJs and MJs, polyurethane mounts are only recommended for rigs that are doing heavy off-roading or other extreme uses.  Because of the unibody construction, Ultra-Flex rubber is recommended for daily drivers and light off-roaders.  You'll find these mounts a serious upgrade from OEM mounts.
 
High performance design.
We engineered these motor mounts for extreme strength, ease of installation, and long-life featuring replaceable bushings. In fact, we believe you'll find these a serious upgrade, especially when encountering the torque often experienced in offroad conditions.
 
Extreme strength.
These Jeep Cherokee XJ & Comanche MJ motor mounts are all steel and feature double-welded 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 high performance motor mount or motor mount lift with a structural failure ... even those used in the toughest competition events.
 
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 inside the left engine bracket arms (that interferes with most other high performance motor mounts) found on most XJ & MJ. You get the full benefit of bolt-in convenience.
 
Classic Polyurethane bushings.

The Classic Polyurethane bushings in this set of Brown Dog motor mounts will give your rig a much sportier feel. Prefer our proprietary Ultra-Flex Rubber bushings? 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 Jeep engine brackets, in the identical position as the stock mounts. No trimming, grinding, or any other modification required.
  • Secures engine into 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 and sheared engine-side bolts. The original brackets weren't designed to handle off-road conditions. If brackets show wear, order S2572-0 or SU2572-0 kit. These kits include include both Motor Mounts, both Engine Brackets, and all new Grade 8 mounting hardware including new through bolts. However, unlike this pair of motor mounts, both the left (driver-side) motor mount and right (passenger-side) kit motor mounts are identical. This makes for a stronger, more comfortable 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. It's difficult, if not impossible, to inspect transmission mount until loosening the nuts holding up the mount. Transmission mounts tend to tear longways. 
  • Tighten thru-bolts (bolt that goes through bracket arms and motor mount) according to the instructions included with the mounts. Do not over-tighten through-bolt lock-nuts or you will get vibrations.  Air tools should not be used here. 
  • These motor mounts will bolt to frame-side brackets in the same location as your original motor mounts. These bolts should be tightened like most others on your Cherokee or Comanche. Nice and tight.  The 10mm bolt on the driver side mount should be torqued to 40 foot pounds.  The nuts in the other positions are prevailing torque locknuts and should be tightened until firm (there is no torque spec).
  • If you have any questions during installation, believe a part will not fit, or have difficulty lining up parts; do NOT alter the part. Call Brown Dog, 866 401-3877 or contact us. We have extended support to assist with installation.
