That is beautiful! Nice job! I'm restoring a King Cab right now and I hope it looks half as nice as what you did on yours. Really looks good. I appreciate what time you took for all that detail. Here are some pics of my restoration. Gen-Atrain

As Pintopower pointed out the Frog dog bones won't work with the MIP differential. I can confirm this. I'm procuring more sets of 2015 CVD's to see if the problem is isolated or not. The trouble with calling Tamiya for replacements is they are issuing the dogbones since they figure that is the cure with a "stock" diff. The best resolution to this issue would be telescoping axles to adapt to the MIP cups. I'm tinkering with a custom hybrid set up as we speak. I'll keep you posted. Gen_Atrain

This post is meant to be for information and is not intended to say one differential is better than another. The facts are easy since Thorp is long out of business and their products are hard to find and when you do find them....very expensive.

@Frog Jumper Well....the Thorp axles really aren't meant to work with the MIP diff cups. The MIP cup slots are wider than Thorp's design. The pin on the Tamiya CVD is double the size of the Thorp dogbone pin. I mocked this up as a demonstrational purpose only. Running would surely wear things out quickly. Plus on AmPro's suspension set up I lengthened the upper wishbone link to accommodate the longer Thorp axle. So the camber is exaggerated and it can't be driven like that. Clear as mud? Gen-Atrain

I made a quick video showing the issue I was having with the stock CVD axles on my Re-Re MB. MIP Super Ball Differential AmPro ORV double wishbone rear suspension Thorp counter gear Tamiya TBLM-02S 10.5T brushless motor On the right side of the vehicle you will find a Thorp dogbone and Thorp axle drive. On the left side of the vehicle you will find the stock Tamiya CVD axle. NOTE: Both inward ball bearings are installed but not the outboard bearings. https://youtu.be/nyp3U4QPZHk Tamiya CVD issues regarding NVH!

@Saito2 "Hey, not bad! I've never seen that approach before, but I like it a lot. Definitely going to give a try on one of my ORVs." 👍🏼 Just remember that if you are using the AmPro's rear suspension then you don't need to do this mod. His rear mount wraps around the gear box and there is no way the plates can spread. But it can't hurt either!

@beefmuffin "So you're having trouble using the CVDs with the MIP diff?" I did. It is caused by the Tamiya CVD and not the MIP diff. I have measured every inch of the MIP diff and believe it or not the face-to-face or cup-to-cup dimension on the MIP is .040" shorter than the stock cups. Gen_Atrain

@Snappy1 No, that is the telescoping Thorp axle without the other side attached. Great design axles IMHO but expensive diff that didn't really hold up well to the Brushless power.

For those of you who want to keep the stock stuff but want to reduce the gearbox from spreading under load. Try this...You need Tamiya's hop up 54319 and you swap out the solid counter gear shaft for the hollow one in the hop up kit. Then you insert a 3mm cap screw to go through both sides and use a nylon lock nut to secure it. Adjust the pressure as needed but not so the gears are being restricted by the case. Shim the counter gear as required (since the diff plate thickness can vary as much as 10%). Enjoy!

Hi guys, I'm new here but I wanted to give some feedback on my set-up. I have a 2015 MB with the MIP super ball differential and AmPro engineering's rear double wishbone suspension set-up. I use a TBLM-02S 10.5T brushless motor. I also experienced major headaches when I switched from the Thorp telescoping axles/Diff to the MIP set-up and the Tamiya CVD axles. The CVD's are binding and causing the back wheels to wobble and make horrible sounds from the velocity joint. I contacted Tamiya USA and they acknowledged the issue and were going to send me dogbones to replace the CVD's. I wish MIP made telescoping axles but that is for another day. At any rate I disagree with the comment that AmPro's arms need to be shortened. I don't believe that at all. His suspension was designed to work with all the ORV's including the Frog. AmPro's stuff is killer and just what this vehicle needs to get rid of the poor control arm design from Tamiya. Back with the first Thorp diff (dogbone style), I also used a Trinity rear sway bar and even still I would occasionally loose the Thorp dogbone axles in a rollover. That is a lot of spreading! Don't hesitate to get the MIP and AmPo combo...you won't regret it! Gen-Atrain
