A few words about motor mount lifts on your Jeep...

 

Myth: A body lift requires a motor mount lift.

Some people say that a motor mount lift must be used with a body lift; that is a myth.  Motor mount lifts (MML) and body lifts (BL) are not related except that a BL would eliminate the need to re-locate the radiator or fan shroud. (Also see 2” MML below.)  A body lift, on its own, is not a valid reason for a motor mount lift. That being said, a motor mount lift can be installed on some Cherokee configurations.

 

Using a motor mount lift to correct drive line angle issues.

Under normal circumstances, motor mount lifts have only one purpose: to help correct drive line angle issues that are causing vibrations and/or u-joint binding.  In fact, installing a motor mount lift on a vehicle with no vibration problems, may cause vibration.  Therefore, it's not really possible to calculate which (if any) motor mount lift is needed, simply by knowing how much lift is installed on a given vehicle. The following link does an excellent job of describing the elements of drive line angle.  Drive Line Angle Information 


How much lift is needed to get rid of drive-line vibration?

As stated before, it's nearly impossible to determine if a vehicle is best with a stock-height motor mount or a 1" or 2" motor mount lift based on the amount of your suspension lift and/or body lift alone.  Most vehicles that have as much as 6” of suspension lift would probably use a stock height or 1” motor mount lift (depending on the remainder of the configuration).  A 2” motor mount lift has no place in most vehicles.  Remember, no motor mount lift will correct vibrations caused by a bent shaft or other failed part.  A motor mount lift will correct drive line alignment problems.  If this is the cause of your vibes, then a motor mount lift can be the solution.

 

About the rare 2" motor mount lift.

Some abnormal circumstances in which 2" motor mount lifts may be useful include an 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 lifts (up to about six inches) and other common modifications of stock vehicles do not fall in this category.  If you are considering installing a 2" motor mount lift, 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.

 

Still not sure which is best for you?
