DragonSlayer

DragonSlayer crankshafts are made in the U.S.A. for American racers. With an expanded line of part numbers the DragonSlayer set the standard by which other sportsman crankshafts are measured.

These crankshafts 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. Our final polishing procedures produce excellent load carrying surfaces that ensure extended bearing life and trouble free operation.

Each Callies DragonSlayer receives our proven Ultra-Case heat treatment. Callies heat treat expertise combined with our high purity premium 4340 forging produce a strength of unparalleled value. All DragonSlayers are produced with standard Chevy Rod journal diameters and widths for SBC, BBC, Mopar and Ford applications.
