Dragonslayer Crankshafts

Dragonslayer cranks are made in the USA for American Racers. These shafts are machined to the tolerances demanded by today's high performance engine builder. Roundness and taper will be held to within .0003 on all rods and main journal diameters. Our finishing procedures produce excellent load carrying surfaces that ensure extended bearing life and trouble free operation.

Consider this a long tem purchase. At Callies we manufacture components for long term service. The unique Callies DuraTough heat treatment will be there working for you even after a .030 regrind. The combination of our high purity 4340 premium grade steel and Callies proven heat-treat expertise produce strength of unparalleled value
