No other engine component is subject to as much stress as the crankshaft. It’s impacted by the explosive force of combustion thousands of times every minute, yet typically will provide many thousands of miles of trouble free service in an unmodified engine. But, hop up the engine for increased horsepower and high RPM use, and that once reliable stock crankshaft can become the pin and your precious engine a very expensive hand grenade.
Many cranks are made of cast iron, which is reliable at factory power levels, but isn’t up to the demands of a performance engine. Also, the constant pounding can cause hard-to-find hairline cracks to develop, and may even cause the crank to bend. If the journals are worn, regrinding may remove the surface case hardening. Don’t run a used OE crank and risk blowing up your engine. Be safe, and make a new performance crankshaft the cornerstone of your build.
We offer performance crankshafts for all popular engines, designed and manufactured by performance crankshaft specialists, in materials and configurations for every use and horsepower output. Cast steel cranks are relatively inexpensive yet can handle some serious power. Next up the ladder in strength and price are forged followed by billet steel cranks. Forged cranks are created by pressure forming heated steel in a die, while billet cranks are CNC machined from solid steel. Regardless of the material, all performance cranks are finish machined to a greater degree of precision than standard replacement cranks.
