Sometimes called a "rear engine mount", these transmission and transfer case mounts are a critical part of the Jeep powertrain's support onto the crossmember or skid pan.
This popular Borg-Warner style rear mount (image, below) is 1-7/8"tall. It matches the bolt holes in most of our adapter housings. It is used on installations where a rear mount can be attached directly to an existing crossmember (or belly pan) or where you may need to make a custom bracket for spacing or bolt hole purposes.
Do not, in any scenario, hard mount a factory or conversion powertrain. Rigid mounting directly to a crossmember will likely cause stresses to break transmission cases, adapter housings, etc. and failure to use a proper rear mount will void the warranties offered by Novak and most other manufacturers.
Used with most Novak adapter attaching to either the adapter itself or to a steel bracket included with the assembly designed for this purpose.
Installation of the RMU will often require a spacer or bracket be made to attach to an existing crossmember or skidplate. This is usually a quite simple procedure. Some guidelines to remember is to keep the driveline parallel to the centerline of the Jeep. That is, the crank centerline should be the same distance from the centerline of the vehicle as the rear output shaft (if the transfer case has a centered rear output, youâll have to get more creative for this on a D18 or Quadratrac). The driveline should tip 3-7 degrees down in the rear.
