Compstar

Compstar Crankshafts are a great value for the budget minded racer or high performance street enthusiast. These cranks are designed by our engineers, and rough machined to our specification on 4340 material forgings overseas. All finish work and quality control operations are performed in our facility.

Our in house solid modeling abilities provide a great advantage in product development. Starting with a clean sheet of paper, Callies design engineers created forging dies that result in a near net forging. Beginning with properly placed counterweights that not only improve balance but reduce bearing loads, every aspect of these highly stressed components has been analyzed. Our forgings are rough machined in a process that includes double stress relief operations that make these crankshafts dimensionally stable.

Compstar cranks are deep nitride hardened, and are ideal for abusive dirt track environments. All rod journals are drilled and counterweights are profiled for piston clearance. With our consistent grind and polish, along with our precise stroke and index, we feel that these are the best value based crankshafts on the market.

Dragonslayer

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. Our 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.

Callies can balance your DragonSlayer up to an 1820 bob weight at a special money saving LS1 price. Our 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.
