Thanks for the response! This is definitely from posts read on the 801xt thread... Lots of good info in there. I will poke around a bit more, but this is helpful info - Thanks man!
I am just digesting as much of the TRF801 thread as I can get and also buying as much needed spare parts as I can. I bought all of RKHESS' TRF stuff and am rebuilding his buggy at the moment. I only have one spare spur gear (OFNA NeXX8 46t, WAY discontinued) which is why I am sending you a message back-channel please. It looks like you have used other spur gears in this center diff without issue. Can you please tell me more about them?
