Compstar Performance
Crankshafts are designed by
our engineers, and forged on
proprietary dies, made to our
specifications. They are
rough machined from certified
AISI 4340 forgings to our
tolerances, then finish
machined in our facility.
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 very
dimensionally stable.
Hardened with a deep nitride,
Compstar cranks are ideal for
all types of abusive racing
environments. All rod ournals
are drilled and
counterweights are profiled
for piston clearance. With
our consistent grind and
polish, along with our
Correct.
