84.4mm Stroke 4340 Steel Billet Crankshaft for Honda B16A

The SpeedFactory Racing BC5018B crankshaft is constructed from 4340 steel billet, a robust material chosen for high-performance applications. This component undergoes a comprehensive multi-step heat treatment process, which includes stress relieving, shot peening, magna flux inspection, and nitriding to ensure maximum durability and performance under demanding conditions. The crankshaft features a stroke of 84.4mm, a 45mm rod journal, and a 55mm main journal. This design element minimizes oil resistance, thereby improving the engine's potential to reach higher RPMs. When considering a stroker kit that includes this crankshaft, note that components such as ACL Race bearings are sold separately. Ensure compatibility with your specific engine build by consulting the detailed specifications for rod and piston pairings.
