I bought a center diff off of ebay, and it is an rtr diff. My question is, when I took it apart... there where shims behind the cross gears???? my pro kit did not have them? is this something new? I find it hard to belive there would be a difference between pro and rtr center diff....

thanks

my pro kit had shims. Are you sure they are not there? mine were stuck pretty good.And yes the diffs are the same.

Funny, I build 3 Pro kits none had shims and the other day I open up a RTR...IT HAD SHIMS.NOW WHAT!!!!

Don't worry about the shims. I believe they are a running change to the diffs. My pro kit didn't have them either. Throw the diff in and run it.

They are a running change. The shim is there to give a better seal for the o-ring.

Not only that i think. When i raced the Xraychallenge in denmark. It was the cars first race, i had the center diff lock up on me. it seemed like the mesh wasnt right. first i changed the diff gears. and it happend again( yes i broke in the diffs). And i remeberd that i had the same problem on my Hyper 8 diff.
So i used shims. newer any problem after that. there where 4-5 other 8 there and none of them had the problem. i think it was my engine. It was a CMB rs 21. it has incredible torq.
