Step Up to a Callies Apex Series Forged Crankshaft for your GM LS or LT Engine

Sometimes the middle ground is just right. That goes for crankshafts for GM LS and LT engines. Callies Apex Series Forged Crankshafts fill the gap between the entry-level Compstar forged cranks and the full-boogie Magnum Series and Billet cranks. Able to support 2,000-plus horsepower, the Apex crankshafts are made on the same premium 4340 forgings Callies uses for their Magnum Series cranks. Callies offers the cranks in a limited range of popular strokes. That makes them more affordable.

Callies Apex Series Crankshafts are deep-nitrided for optimal hardness and wear resistance. They are finish-machined and inspected in-house at Callies’ USA-based facility. All cranks are set up for 58x reluctor wheels.
