Quality. Innovation. Performance. The hallmarks of Arrow Precision. Only the highest quality raw materials, the latest methods and the knowledge of superbly skilled designers and engineers goes into the making of every Arrow Precision part. Constantly experimenting on behalf of our ultra-performance-oriented customers has led to the development of several product innovations that raise the level of extreme performance.

Our steel con rods are fully machined in-house from our own specification double air re-melted 817M40 forgings. All rods are shot peened using our automated process to increase fatigue strength and durability. The rods are balanced end over end into matched engine sets and are 100% magnaflux crack detected prior to final inspection by CMM in our temperature controlled inspection department.

Crankshaft manufacture begins with either a solid billet of our own specification 722M24 or other commercially available aerospace grade steels.

Experience true durability, reduced friction and higher performance through 30 years of Arrow Precision innovation. Machined from solid steel, Arrow followers feature thin walled sections in combination with a strengthening rib to minimise weight without compromising durability.

Reliability is further enhanced through careful material selection and controlling the surface finish on the working face to within 0.2Ra.
