Description
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 84mm Stroke.
The flywheel is locked in place with 6 hardened dowel pins and 6 7/16-20 12 point ARP Pro Bolts, sold separately.
Match the CB Pro-Flanged Crankshafts with our industries first Pro-Flanged Main Bearings for a winning combination.
Finally… Professional engine builders or the do-it-yourself builder at home can easily assemble a performance flanged crank engine. No more hassles of expensive custom-made bearings and thrust conversions.
Pilot Bearing Included – Installation may be required.
NOTE: Prior to installation of CB’s Pro-Flanged Main Bearings, your engine case will need to be machined for bearing tangs and flanged crank rear main seal. CB Performance offers these services for new engine cases, Aluminum or Magnesium.
