Hub - RCD Big Block Chevy Bearing Support Crank Hub with Retaining Ring

RCD BB Chevy Brg Support Blower Hub

for use with the RCD Crank Support

Our crank hubs are machined from heat treated chrome-moly steel billet.

  Each hub has two 1/4” keyways 180° apart, six 3/8-24 threaded holes in an evenly spaced pattern and a black oxide finish.

  A stepped profile is machined around the holes for weight reduction and to lock-on the degree ring.
