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!

    great ball!
    Size: Medium (2.5"), Style: Fetch Pack 2
    My pitbull LOVES these. She is a power chewer and tough on balls and toys and tends to go through them insanely quick. She is still on her first ball out of this pack and its been at least two months. It is a little small for her mouth but she doesn’t seem to mind, as it has quickly become one of her favorites. Not a loud ball and it doesn’t usually make that wet chewy noise when shes going to town on it which is huge for me😂😂 Safe for my pittie so i’d imagine a smaller dog would be just fine.

    Border Collie Approved: Easy to Clean, Durable, and Great Bounce
    Size: Medium (2.5"), Style: Fetch Pack 2
    These are the best balls out there for dogs. These fit great in the chuck-it ball launcher, which we need to wear out my border collie. They fit her mouth properly and, most importantly, do not absorb all the spit or water after a good rain. They are quick to clean off and have good weight so you can let them fly! Furthermore, they bounce well, which is perfect for my dog that likes to catch them on a bounce. The ball is a strong rubber, so should not be easy to chew up. I've used these for years, and the only time I've had to replace them is when one gets lost in the hay field. I highly suggest these as replacements for the common tennis balls.

    Treats and plenty of ball throwing with these doggie toy
    Size: Medium (2.5"), Style: Fetch Pack 1
    I have actually purchased these twice already. I love the one that glows in the dark but it still got lost in my yard lol. My dog is a big breed half pitt/Labrador so she did chew through one of them already. I play ball with her every single day but I DO have to take them away from her because she will destroy them. They are great to add in treats as well, that was one of the my favorite things about them as well. They do last just if you have an over zealous chewer do not let them keep them for long periods of time. They are a good value for the price. Buy them your dog will love it!

    My Female GSD loves
    Size: Medium (2.5"), Style: Fetch Pack 1, Size: Medium (2.5"), Style: Fetch Pack 1
    Shasta is my smallest. Six in December (2025) along with her brother. She’s 100 lbs and outside, completely ball driven see last picture. Don’t let the size (2.5”) of these Chuck-It balls deter you. If your larger Breed dog has any orthopedic issues, has already torn their ACL etc, one has arthritis but wants to play. This size is perfect! Shazzy was born with several ortho issues. I don’t throw balls distance but right to her. This size and lighter weight assure even when Shazzy is spazzy w excitement, she’ll catch the ball mid air. The green balls are softer, and glow in the dark. In summer we can play well past dusk and I can see them! Her personality shows in the pictures. Playing ball is part of her. These balls are just perfect for her situation. Somehow they disappear, she loves making baskets, puts them in my tractor bucket, or my gardening bucket..then get put in burn pile, trash etc. I keep replacing them because she’d look day and night if we actually ran out!! 🙏✝️👍🏼👍🏼
