Callies Compstar Forged Crankshafts
- 4340 Forged Competition Crankshafts
Designed by our engineers, rough machined to our specification on 4340 material forgings, then finished in our Ohio, USA, facility, these crankshafts are Callies Compstar correct. Beginning with properly placed counterweights that not only improve balance but reduce bearing loads, every aspect of these highly stressed components has been engineered and analyzed. Our forgings are rough machined in a process that includes double stress relief operations that make these crankshafts dimensionally stable. Hardened with a deep nitride, Callies Compstar crankshafts are ideal for high load, abusive and dirt track environments. All rod journals are drilled and counterweights are profiled for piston clearance.
