Step Up Your Rotating Assembly with Callies Performance Compstar Cranks and Rods
Callies' Compstar 4340 steel forged crankshafts for small block Chevy, big block Chevy, and GM LS engines give you pro-racing quality and reliability at a price that's well within reach of the average sportsman racer.
All design work, quality inspections and certifications, and final machining are done in the USA by Callies. That means you get a crankshaft with proper geometry, strength, and weight, finished to proper tolerances. In other words, you get a Callies crankshaft.
Available in standard weight, mid-weight, and lightweight versions, Compstar cranks are deep nitride-hardened, have drilled rod journals and cross-drilled main journals, and profiled counterweights for piston clearance in stroker applications.
Compstar H-beam forged connecting rods are available for small and big block Chevy. The forged 4340 steel rods are put through a lengthy stress-relief process and burnishing of threads and bolt spot faces to ensure dimensional repeatability, no matter how many times rods are torn down and reassembled. Pin bushings are chamfered and honed, parting line edges are generously chamfered, and bearing locating tab slots are deburred.
Most Compstar connecting rods are fitted with ARP 2000 or ARP L19 bolts and clearanced for stroker combinations.
