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!

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!

    The magnet does not stick to the refrigerator as advertised.. UPDATE ( I love it and it does stick)
    Color: Pink
    Although it is a nice case, it seems sturdy and it is very beautiful, my main reason for purchasewas I loved the fact that it sticked to the refrigerator. I was very disappointed to see that it does not. It’s too heavy, and it immediately begins to slide. That is the reason why I could not give it more than three stars. It disappointed me enough to where I’m really considering returning the item. UPDATE: I found out how to make a stick to the refrigerator and I absolutely love it! I changed my review and my stars! I’m really happy.

    Great Protection, Great Fit — One Small Flaw
    Color: Forest Green
    I really love this case. It protects the iPad well, fits perfectly, and is still easy to put on and take off. The pencil holder is especially nice — it keeps the Pencil secure without feeling loose or flimsy. My only complaint is that some USB‑A to USB‑C adapters don’t have enough clearance to plug in. The edge of the case blocks certain adapters from seating properly. It’s the only issue I’ve run into, but it’s worth mentioning if you rely on chunkier adapters. Aside from that, this is an excellent case and one I’m happy to use every day.
