I'am to look at my revo to install/fit a Ofna Ultra LX 1/8 buggy center diff on my revo. If all fit like i want,.............talammmmmm!!!! no more trouble with the tranny. Pair with my RCM V1 hybrid diffs, souhld be a solid setup.
For answer to ZPB steel input gear, realy don't know if the Steel gear against the plastic 2-speed gear will hold up long.
And for the wet lub setup, forget it, the oneway bearing in the first speed gear will slip at fisrt run.
