Spec-R Gear Diff in the M-05 Mini
I've run the TA-03 ball diff in my M-03 and recently in my M-05 mini for years and I never had much to complain about. Built right with AW grease and tightened properly they last forever.
When Spec-R came out with their new gear diff for the M-05 I was pretty excited. I run one of their gear diffs on my FF-03 Pro with excellent results and thought that the one for the M-05 would be just as good.
I bit the bullet and ordered one directly from Spec-R. On arrival, I wasted no time with the install and went racing. The thing lasted one race day before one of the internal main gears snapped in half along with the steel washer. The diff is destroyed and I must say I'm not impressed. The outer housing, main O-ring and the diff outdrives seem fine but the remaining internals are junk. The main housing might also be ruined as the gears ground themselves into a paste with the silicone diff fluid. What a mess.
Anyone else had any issues with these gear diffs?
