Callies’ value driven

Compstar Step by Step:

• Compstar
  crankshafts begin their life
  overseas where they are
  forged using Callies owned
  dies. Not generic forging
  that other manufacturers use.
  You can be confident that
  you’re getting our
  product by the triangle
  shaped notch in one of the
  counterweights. 
• The 4340 steel forgings are
  semi-finished, machined
  off-shore, then shipped to
  Callies to be finished.
• All Compstar components
  are 100% Mag Particle
  inspected to verify there are
  no cracks or inclusions in
  the material. Additionally,
  our in house metallurgical
  laboratory verifies
   material and heat
  treatment to ensure it meets
  Callies engineering and
  quality requirements.
• 100% of our Compstar
  crankshafts are finish sized
  and polished by American
  craftsmen, ensuring proper
  fitment and widths.
  Additional items checked are
  runout, bolt holes and
  oil holes.
• Every
  crank then goes through our
  stringent Quality Control
  final check, guaranteeing
  your Compstar Engine
  Component is ready to race.
