Can I bring this subject up again.

Just broke the planet gears on 2 different 7.5" diffs in less than 3 miles driving!! with no heavy launches what so ever.
And one of these was un uprated VC and shot peened gears!

Need to find better options asap. for track use.

Marco, Thanks for the info on the plated diffs, re Kelv. But want to find out the best route to take.
