Better by design. Compstar Performance Crankshafts are designed by their engineers, forged on proprietary dies, and made to their specifications. They are rough machined from certified 4340 forgings to their tolerances, then finish machined in their facility.

Their in house solid modeling abilities provide a great advantage in product development. They’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. Their 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 journals are drilled and counterweights are profiled for piston clearance. With their consistent grind and polish, along with our precise stroke and index, you will see why they say these crankshafts are Compstar Correct.

Please Note: All crankshafts must be balanced for their rotating assembly by a qualified engine machine shop before installation and use
