The carrier bearing for a CLUTCH type sure grip is a Timkin PN 25590. (the race is P/N 25520)

The AZ Duralast has the same P/N, but the box said made in China..... the part said USA. I'll take it

The new sure grip side/spider gears that Dr Diff sells are an up-grade and provide more spline engagement.



The thrust button should measure 1.500 when new, if it's worn more than 0.010 replace it

ARP bolts p/n 250-3006 are made for the Mopar clutch type sure grip
