It's been modified. I trimmed the hook off the end then separated the bottom piece, fits perfect. People at the track give me crap about a TLR part on a Kyosho. haha

The Gen3 bulldog is better then the stock body IMHO. I haven't tried the phantom yet.

Does anybody know if the mip aluminum puck system is compatible with the kyosho gear diff? This one is listed as for a gear diff but I was unsure if it will work with the stock gear diff and the included out drives

Yea dude that works. I ordered the regular ball diff puck kit and then ordered the gear diff outdrives separately, just to have both options. But the kit u linked is good to go w gear diff

I’m going to order my Puck system for next season 17.5 stock racing soon but just wanted to know something.

It says that you need the following 3 items:
Kyosho Tensionner Spring- UM124
Kyosho Ball Diff. Screw Set - LA208
Kyosho Diff. Gear Set - UM509

I am wondering is that diff screw is the correct one or should I get the RB6 one (TF120)?
Also is the gear diff UM509 needed as it has a diff supplied in the kit listing?

http://miponline.com/store/mip13165.html

Cheers for any help

All those parts are correct. Unfortunately out of the um509 your only using the little white t thing that the nut sits in that goes into the outdrive.

I actually used all those parts from my stock kyosho ball diff.
