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 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
