Pit Stop USA is The Online Motorsports Superstore! Callies Performance Products began manufacturing high performance crankshafts in 1989. With many years of engineering and employee experience, Callies has grown to be the industry leader for innovative product design. Callies Performance Products takes pride in staying ahead of the competition with the latest high tech design and manufacturing advantages. By utilizing the latest in computer aided solid modeling and CNC machining centers, Callies is able to offer the best designed, highest quality crankshafts available on the market today. Every crankshaft is 100 percent inspected for critical dimensions, and the manufacturing equipment is constantly monitored for tolerance drift and tool degradation. At Callies, quality and durability really are a driving force behind Callies products. After years of service, Magnum crankshafts by Callies have established themselves as one of the most durable competition crankshafts ever produced. Magnum crankshafts are manufactured from ultra pure AISI 4340 steel. Callies then subjects this material to multiple heat treatments including our proven Ultra-Case nitride process. This heat treatment method produces a deep case that enhances strength while creating an extremely hard load bearing wear surface. The Ultra-Case process generates a layer of hardened steel deep enough to maintain its integrity even after a -.010 regrind. All Magnum cranks will have gun drilled mains and fully profiled counterweights, regardless of engine type. A typical 4.000 inch stroke Small Block Chevy will weigh less than 48 pounds. Magnum crankshafts are available for a variety of engine types and can be manufactured to your specific configuration. We feature Callies Magnum Crankshafts at low everyday prices.
