Billet Crankshaft

Arrow lightweight billet crankshafts are designed to handle the added stress of high performance and high rpm operation. Machined from low sulphur CoORUS steel in EN40B specificaiotn. Oil drillings in the crankshaft are designed to improve oil pressure at the rod bearings particularly at high rpms where the stock crankshaft suffers issues due to centrifugal forces acting against oil flow. Profiled counterweights reduce drag and large fillet radiuses maximize strength. Each crankshaft goes through a rigorous quality control process and is precision balanced. A detailed inspection report is included with every crankshaft.

These crankshafts incorporate thrust surfaces for both #3 and #5 main journals and therefore can be used in any model year application (Phase I or Phase II engine designs).

Usually ships in 1 to 2 weeks.
