Arrow's range of stock crankshafts are manufactured to the highest standards using their own specified 722M24 (EN40B) British low sulphur grade billet steel. A detailed manufacturing route plan allows full progress monitoring and traceability. Their modern plant includes CNC lathes, 4-axis mills and 5-axis machining facilities plus a state of the art CNC grinding machine.

All crankshafts are either stabilised or harden and tempered, dependent on engine specification. The nitride hardening process cycle lasts for 90 hours creating a consistent hardness and depth. All crankshafts are magnaflux tested, balanced and have a unique controlled super finished process which creates a .1 Ra finish on all pins. Their well-equipped, temperature controlled inspection department gives accurate control when measuring the finished parts. All critical details are recorded and great care is taken in the packaging of your Arrow crankshaft.
