Recently busted the pinion gear in my Dana 60, never used pro gears in several years of racing, but I don't want another failure. Pros and cons? How long will pro gears last? Had 4.56 but had been planning to switch to 4.10's. 1.32 60' @ 3,200 lbs. Thanks for all input.



Are you running too many rpms at the traps to cause
you to go with the 4.10s... I myself have never run
a pro gear.. mainly due to it wasnt in my ratio.. so
I cant help there
