Crankshafts

Performance Crankshafts & Billet Cranks

The crankshaft converts the reciprocating motion of the pistons and connecting rods into rotational torque that drives the transmission and ultimately the wheels. Performance crankshafts are forged or machined from billet steel for superior strength, balance, and fatigue resistance compared to factory cast cranks — essential for engines producing serious power or operating at high RPM.

OneFastShop carries performance crankshafts including forged 4340 steel crankshafts, billet steel crankshafts, stroker crankshafts for increased displacement, standard-stroke replacement crankshafts, and application-specific cranks for popular performance engine platforms.

Every crankshaft at OneFastShop ships brand-new with manufacturer warranty coverage. Whether you're building a stroker motor for more displacement, replacing a damaged factory crank, or assembling a no-compromise race rotating assembly, OneFastShop has the crank.
