***note - temporarily out of production***

Dragon Slayer crankshafts are made in the U.S.A. for American Racers.  With an expanded line of part numbers, the Dragon Slayer is rapidly setting the standard by which other Sportsman crankshafts are measured.  These shafts are machined to the tolerances demanded by todays high performance engine builder. Roundness and taper are held to less than .0003 on all rod and main journal diameters.  Final polishing procedures produce excellent load carrying surfaces that ensure extended bearing life and trouble free operation.  Each Dragon Slayer 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.  Callies heat treat expertise combined with high purity premium 4340 forging produce strength of unparalleled value.
