The world's best Transfer Case Support/Ring Mount for the Midnight Metalworks D300 Rock Box, or any Dana 300 running the JB Conversions Rear Output! 

***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 about what you spent on your Midnight MetalWorks transfer case, is now the time to cheap out?

    Includes the following:

    • transfer case support ring 
    • 2 x poly bushing halves 
    • DOM tubing inner and outer sleeves
    • all necessary grade 8 fasteners
    • 2 x mounting tabs

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

    These hold up very well
    Color: White, Size: Standard (Pack of 2)
    I have NO luck with pillows. I’ve been in stores & tried them. They seemed ok there. At home, nope. I’ve been getting headaches & neck aches from lousy pillows. I’ll change one, a few nights relief. It doesn’t help that I’m prone to headaches. After reading about different pillows, I settled on these. The reviews were better than so many different ones I was looking at. Including high priced & brand names. I bought the standard size. When I saw, “Customers Usually Keep This”, I kept my fingers crossed. When I received them, I took one out of the package & put my head on it & thought, oh no! This is too hard! I tried it again. Ok….. I slept on it & haven’t had any pains since. It’s soft but firm enough to keep my head from sinking & messing up my neck. I don’t move. No more flipping my pillow over. My head doesn’t go below my neck anymore! This has been 2 months now, but it hasn’t changed at all. I wake up happy, not complaining. No more pains or headaches. This saved me from losing days with a heating pad or an ice pack. The price was excellent for 2 pillows. I can’t believe a blind buy was the answer! These are incredible. Finally, something worked for me.

    Awesome Pillows!
    Color: White, Size: King (Pack of 2)
    These pillows are super soft! I love them. I bought them when I caught a bad cold and needed to prop myself up. Worked so great! Definitely give these pillows a try. They're very reasonably priced too.

    Inexpensive and Nice Quality
    Size: Standard (Pack of 2), Style: Medium, Configuration: Hometextile
    I was hoping there would be more of a firmness to these pillows, however they are more soft than I was expecting them to be. Id recommend these pillows for someone who wants a fairly non firm pillow.
