The world's best Transfer Case Mount for the Midnight Metalworks D300 Rock Box!

***NOTE: MIDNIGHT METALWORKS TYPICALLY BUILDS THEIR D300 ROCK BOX USING JB CONVERSIONS OUTPUTS. IN SOME INSTANCES THEY ARE USING A NOVAK SUPER SHORT OUTPUT. THIS MOUNT WILL ONLY WORK WITH THE JB CONVERSIONS OUTPUT, IT IS NOT COMPATIBLE WITH THE NOVAK OUTPUT! IF YOU ARE UNSURE WHICH YOU HAVE PLEASE CONTACT US FIRST!

TMR Customs Transfer Case Supports uses hex head bolts for clamping instead of cap screws for easy install and to prevent stripping the cap screw head.

The profile of the ring is cnc machined and the center is cnc bored to a slip fit to precisely match the output housing.

The precision bore is a perfect fit onto the machined surface of your transfer case output - other thin/cheap laser cut and plasma cut mounts will fail. Think what you spent on your Midnight MetalWorks transfer case, is now the time to cheap out? 

  • Fits MWW D300 & JB Conversions D300 HD Output

Designed to be bottom mounted to a crossmember. Do not mount upside down!


We're wheelers too - we back every product with the TMR Customs quality guarantee. Our products are designed to be the ultimate in durability and withstand years of abuse. So go ahead and abuse them in the dirt and rocks - just as they were intended!

DESIGNED, MANUFACTURED AND TESTED BY TRUE OFF ROAD ENTHUSIASTS!

Works great!

Been running this support on my tube chassis tj for a few years now, solid mounted like the rest of my powertrain.

Works great and easy to setup

FIT LIKE A GLOVE

This flange fit my atlas case like a glove! I mounted it to the back of my case and mounted on a bushing to my crossmember. In the end I should have bought the kit with the bushings and tabs but I had some parts lying around I made work but the kit would have been much easier.
