Description
A forged crankshaft is the backbone of any high-revving Small Block Chevy engine, and the Eagle SBC 4340 delivers the strength and reliability required for sustained performance at the track or on the dyno. The 3.480-inch stroke paired with lightweight construction reduces reciprocating mass, allowing your engine to achieve higher RPM capability while maintaining the internal balance characteristics necessary for smooth operation. If you’re building a competition engine or upgrading a tired stock crank, this forged 4340 steel unit provides the durability to handle forced induction, nitrous, or aggressive naturally-aspirated power without compromise.
