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.
Our in house solid modeling abilities provide a great advantage in product development. We're able to precisely locate material where it will yield the greatest advantage in terms of both strength to weight, and balance ability.
Beginning with properly placed counterweights that not only improve balance but reduce bearing loads, every aspect of these highly stressed components has been analyzed.Ourforgings are rough machined in a process that includes double stress relief operations that make these crankshafts very dimensionally stable.
