Overview
Callies Apex Crankshafts
Utilizing the latest in computer aided solid modeling and CNC machining centers, Callies offers the best designed, highest quality crankshafts, connecting rods, and camshaft inventory available on the market today.
Callies understands not everyone has the need or budget for a Magnum or billet crankshaft, but still may want a product with more to offer than their Compstar line. Callies went to work for a solution, which culminated in the creation of their Apex Series of crankshafts. The Apex crankshafts are made on the same forgings that Callies uses to make their Magnum Series but are machined by the supplier that makes the Compstar line. Like Compstar, the Apex crankshafts are finish sized and fully inspected in-house. This results in the best bang-for-your-buck crankshaft on the market. Callies takes pride in staying ahead of the competition with the latest high tech design and manufacturing advantages of their products.
Callies Apex LS/LT standard features include:
* Made on Callies proprietary Magnum forging
* Ultra-pure, premium 4340 material machined by Callies vetted and reliable Compstar supplier
* Machined by Callies vetted and reliable Compstar supplier
* Nitrided for optimal hardness and wear resistance
* Every crankshaft is finished and inspected in-house at Callies Limited stroke and pin size combinations
