Compstar components were
introduced in 2004 as a
product line designed to meet
and exceed the requirements
of today’s racer at a
sensible price point.
Callies’ value driven
< approach is to design and en
gineer here in the U.S., then
source through long term
vendors, supported by our
engineers, giving us distinct
technical and quality
advantages. This coupled with
our American craftsmen, that
finish the components at our
facility in Fostoria, Ohio,
create a combination that is
considerably more robust and
stable than our competitors.
We are not just an importer
of product, we are a
manufacturer that wants to
bring products to our
customers at all price
points.
Compstar Step by Step:
- Compstar
crankshafts begin their life
overseas where they are
forged using Callies owned
dies. Not generic forging
that other manufacturers use.
You can be confident that
you’re getting our
product by the triangle
shaped notch in one of the
counterweights.
-
The 4340 steel forgings are
semi-finished, machined
off-shore, then shipped to
Callies to be finished.
- All Compstar components
are 100% Mag Particle
inspected to verify there are
no cracks or inclusions in
the material. Additionally,
our in house metallurgical
laboratory verifies
material and heat
treatment to ensure it meets
Callies engineering and
quality requirements.
-
100% of our Compstar
crankshafts are finish sized
and polished by American
craftsmen, ensuring proper
fitment and widths.
Additional items checked are
runout, bolt holes and
oil holes.
- Every
crank then goes through our
stringent Quality Control
final check, guaranteeing
your Compstar Engine
Component is ready to race.
