RCD Hemi Crank Gear PSI Spline Undersize .010"

The gear uses the twenty six tooth PSI spline pattern that the crank has to have for the gear to work properly. This gear will interchange with all RCD and most other gear drives such as Donovan, Indy, TFX and Casale. This gear uses no woodruff keys and the crankshaft has to be set up to use this type of gear.

The finish is black oxide. Perfect for when a engine block must be line honed moving the crank up in the block making a stock size crank gear to tight.
