Do I need a 1.5" or 2" MML?
Probably not.  Some abnormal circumstances in which 1.5" or 2" MMLs may be useful include extreme suspension lift, custom frames, custom engine installations, or bodies that require a particular engine position due to an out-of-the-ordinary configuration. Most typical suspension lifts (up to about 6") and other common modifications of stock vehicles do not fall in this category.  

If you are considering installing a 1.5" or 2" MML,
 • Please check for enough clearance between the bell housing and floor pan.
 • Also check for enough clearance between the valve cover and the hood; this can be done by putting a ball of modeling clay on the highest part of the valve cover and closing the hood (measure the resulting ball).  
 • Remember, you're moving the entire engine assembly 2" upward at the radiator fan.
 • Do all of the research and homework you can.  Call us, or chat with people on Jeep Forum or NAXJA.  Find people who have done it, or those who have considered it.  This is not your everyday modification.  Be sure you know what you are doing.


Jeep Motor Mount Lifts, 2" 
This is a radical modification.  Do not use this only because you are installing a 2" body lift.  It WILL change your driveline angles.  Call us if you need help deciding.
Do you want Jeep motor mount lifts (MMLs) to help compensate for driveline angle problems caused by an extreme suspension lift? Have an abnormal modification that's impacted driveline angle? Brown Dog designed these motor mount lifts to reposition your engine a full two inches higher than stock (at the cooling fan). This modification results in a dramatic change in the driveline angle. 

The Brown Dog has experienced a couple busted stock motor mounts himself, on his own Wrangler. 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. We use plate steel. We also double-weld joints to provide the most strength possible. And, just to make sure, why we periodically pull one off the shelf and put it through our 20-Ton Press Test. We've never seen a structural failure of our mounts. These will be the last set of mounts you'll need. The Brown Dog gives you his promise.
 
Ultra-Flex Rubber replaceable bushings work to dampen drive-line vibration. So, if your Jeep is also your daily driver, be sure to get a Ultra-Flex Rubber MML. If you're not sure whether Classic Polyurethane or our proprietary Ultra-Flex Rubber is best for you, compare them here.

Installation Notes: 
  • Before ordering 2" MML, check other components under the hood to be sure you have enough room for a 2" MML. Engine will be raised 2" at the stock cooling fan.
  • Motor mount lifts bolt directly to the pylon in the identical position of the stock mounts except right (passenger side). Please note, on 2.5L (4 cylinder) 1991-1995 YJ, 1991-1996 XJ, and 1995-1996 MJ, the passenger side (right) mount bolts to a cradle which, in turn, bolts to pylon. If in good condition, you may wish to reuse your existing cradle. Cradle (CR2569) available separately.
  • You will experience significant interference between 2" MMLs and the lip on the original Jeep engine bracket. Significant grinding on the original bracket lips will be required so the 2" MML clears. To avoid this bracket modification we suggest upgrading to one of the upgrade kits below. (Note: Original Jeep brackets will not interfere with Brown Dog MMs and may have minimal interference with 1" MMLs.)
  • Inspect your engine brackets carefully for any cracks or other signs of weakness. If you suspect bracket weakness, consider an upgrade kit.
    • KU2569-2, Upgrade Kit for 1997-2002 2.5L Wranger TJ, includes 2" MML and Lipless Engine Brackets. 
    • XU2569-2, Upgrade Kit for the following vehicles, includes 2" MML, Lipless Engine Brackets and Support Cradle for the right mount to sit on.
      • 1991-1995 2.5L I4 Wrangler YJ
      • 1991-1996 2.5L I4 Cherokee XJ
      • 1991-1992 2.5L I4 Comanche MJ

Application Notes

  • Ideal for use with Brown Dog B2569 series engine brackets.
  • If used with OE brackets, shims to fit right side. Expect to grind/remove less than 1/8" left bracket arms.
