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.
