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.
