Callies COMPSTAR Crankshafts
COMPSTAR Crankshafts are designed by Callies engineers and are rough machined to Callies specs on 4340 material forgings, then finished in house.

Beginning with the properly placed counterweights that not only improve balance but reduce bearing loads, every aspect of these highly stressed components has been analyzed. The forgings are rough machined in a process that includes double street relief operations that make these crankshafts dimensionally stable. Hardened with a deep nitride, COMPSTAR cranks are ideal for abusive dirt track environments. All rod journals are drilled and counterweights are profiled for piston clearance.

Most SBC's will internally balance without expensive heavy metal.
Tech Tips
We do NOT recommend the following:

  • Driving on your damper with a mallet

  • Using timing sprockets with more than 3 keyways

  • Balancing externally

  • Welding on or attaching weights

  • Storing your crank without a protective bag & rust inhibitor

  • Assembly without physically checking rod and main bearing clearances

  • The use of straight weight oils without an oil pan heater
