Jeep Cherokee XJ & Comanche MJ 1" Motor Mount Lifts (Pair)
Want Cherokee XJ or Comanche MJ motor mount lifts (MMLs) to give you more ground clearance? The Brown Dog designed these Motor Mount Lifts to reposition your engine one inch higher than stock (at the cooling fan). This modification results in a slight increase in ground clearance.

Will It Fit?
That is an important question.  Some older model XJ and MJ vehicles will accept a 1" MML; that's one reason we offer them (and for vehicles being made into offroad only buggies).  As far as stock XJ/MJ vehicles go, the prohibiting factor is the top of the engine assembly's distance from the hood.  You should carefully check it before ordering any MML for these vehicles.

 
High performance design.
We engineered these Motor Mount Lifts for extreme strength, ease of installation, and long life. In fact, we believe you'll find these a serious upgrade, especially when encountering the torque often experienced in offroad conditions (and even on the streets and highways where potholes make it seem like offroad). 
 
Extreme strength.

These Cherokee XJ and Comanche MJ Motor Mount Lifts are all 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 structural 20-Ton Press Test. We have yet to see a Brown Dog motor mount or motor mount lift with a structural failure ... even in grueling competitive conditions.

 
Slide directly into original equipment engine brackets.
Unlike most other high-performance motor mount lifts, Brown Dog Motor Mount Lifts do not require trimming the driver-side bushings or grinding the lip off the original 4.0L engine brackets. Our left (driver side) motor mount lift design accommodates the lip cast into the original bracket. You get full benefit of the bushings with bolt-in convenience. (Please see below about a possible conflict resulting from Motor Mount Lifts repositioning of the transmission bell housing and the 'hump' in the floorboard.) 

 

Ultra-Flex Rubber Bushings.

Our proprietary Ultra-Flex Rubber bushings were 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? We offer all motor mounts and motor mount lifts with either polyurethane or rubber. In fact, they are intechangeable. Not sure which is for you? Click here.

 

Backed by Brown Dog Promise.
Brown Dog motor mounts will be the last set of mounts you'll need. The Brown Dog gives you his promise.


Installation Notes
  • Engine is raised 1" at the stock cooling fan. This will change the driveline angle. It also increases ground clearance. 
  • Important - Prior to ordering, be sure to check distance between your transmission bell housing and the floorboard for a possible conflict. Some XJ will not require any modification here. Other customers report a slight nudge with a 3 lb. sledgehammer does the trick. Still others build in clearance using a torch or cutting wheel and setting the floorboard up slightly. Measure carefully and plan accordingly.
  • Carefully inspect engine block bolts and brackets for any excess wear, especially sheared bolts or broken thread bosses. You may wish to upgrade your engine mounting system by installing our SU2572-1 which includes these 1" Ultra-Flex rubber motor mount lifts, both Super Engine Brackets, and all new Grade 8 mounting hardware including new through bolts. 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 likely 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 thru-bolts (bolt that goes through bracket arms and motor mount) snug. Do not over-tighten through-bolt locknuts. Please remember, locknuts are for one-time use only. If removed, they should be replaced, not re-used. Air tools should not be used here. 
  • These motor mount lifts will bolt to frame-side brackets, in the identical position as the stock 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.
