Callies Performance Products began manufacturing high performance crankshafts in 1989 with a commitment to excellence in manufacturing and the highest level of customer service possible.  Every Callies crankshaft is 100% inspected for critical dimensions. Each rod and main journal fillet is manufactured to .125 radii to ensure durabality.  Their precise production efforts deliver more accurate dowel pin placement, indexing, stroke length and a perpendicular crank flange. Concentricity and surface finish are the two most desireable features in a high performance crankshaft journal. Each journal must be perfectly concentric to its specified centerline, and journal surface lobbing. Callies limits theirs to no more that .00006" to further enhance oil film integrity at high engine speeds.

DragonSlayer crankshafts are made in the U.S.A. for American Racers. With an expanded line of part numbers, the DragonSlayer is rapidly setting the standard by which other Sportsman crankshafts are measured.

These shafts are machined to the tolerances demanded by today’s high performance engine builder. Roundness and taper are held to less than .0003 on all rod and main journal diameters. Their final polishing procedures produce excellent load carrying surfaces that ensure extended bearing life and trouble free operation.

Each DragonSlayer features the Callies Ultra-Case nitride treatment. 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.

 

LS1 crankshafts are machined from premium 4340 forgings. Each Callies LS1 features PERMA-TOUGH heat treating for added strength and serviceability. DragonSlayer LS1 crankshafts are sold with gun drilled mains and Angalite drilled rod journals.
