The Brown Dog has experienced a couple busted stock motor mounts himself, on his own Jeep. This is why we engineered these high performance motor mounts for extreme strength. You'll find these mounts a serious upgrade from most other mounts, too.

High Performance Design.
We use 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 20-Ton Press Test. We have yet to see a Brown Dog motor mount or motor mount lift with a structural failure.


Featuring Ultra-Flex Rubber Bushings.

Our proprietary Ultra-Flex Rubber bushings were designed to dampen drive-line vibration.  If this is your daily driver, you may find these bushings may 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 to match your preference. Not sure which is for you? Click here.



Installation Notes

  • Mounts bolt directly to the pylons (frame-side brackets) and slide into original engine brackets with no trimming or grinding. 
  • Secures engine in the original stock position.  
  • Carefully inspect engine brackets for any excess wear, especially cracks. The original brackets weren't designed to handle the strength of these high-performance motor mounts. If brackets show wear, order appropriate kit for your vehicle engine and year. All Brown Dog Kits include both motor mounts and both engine brackets. 
  • Tighten through-bolts (bolt that goes through bracket arms and motor mount) snug. Do not over-tighten through-bolt lock nuts. Please remember, lock nuts are for one-time use only. If removed, they should be replaced, not re-used. Air tools should not be used here. 
  • Pylon bolts should be tightened like most others on your Jeep frame. 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. We have extended support to assist with installation.
