Callies LS Apex 4340 Forged Steel Crank 4.125 Stroke
Crankshafts are manufactured from 4340 forged steel and utilize the same forgings as the Magnum series, yet are machined by the same supplier that produces the Compstar line for improved affordability. Each crankshaft is nitrided for optimal hardness and wear resistance prior to being finished and inspected in-house at Callies.
