Pro-Flanged Crankshafts are manufactured using an E4340 Chromoly multi-struck forging. The forging is CNC machined to utilize Type-4 VW main bearings and Chevy 2" rod bearings. We treat the Pro-Flanged Crankshafts with white nitride for extreme durability. The Pro-Flanged Crankshaft is shot-peened to relieve stress, and micro polished on all of the bearing surfaces. Also available in
86mm Stroke.
The
flywheel is locked in place with 6 hardened
dowel pins and 6 7/16-20 12 point
ARP Pro Bolts,
sold separately.
