Callies understand that noteveryone has the need or budget for a Magnum or billet crankshaft, but still may wanta product with more to offer than the Compstar line. This middle-ground has needed an option for several years, so Callies went to work for a solution. This has culminated in the creation of the Apex Series of crankshaft by Callies. Apex crankshafts are made on the same forgings thatwe use to make the Magnum Series, but are machined by the supplier that makes the Compstar line. Like Compstar, all Apex crankshafts are finish sized and fully inspected in-house. This results in the best bang-for-your-buck crankshaft on the market.
