Arrow Precision steel con rods are found in almost every arena of motorsport as well as in a wide variety of the world’s most prestigious motor vehicles.
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.
Our design team works closely with each customer using the latest CAD CAM technology to optimise each design whether it be a fully 3D machined prototype for an OE application or custom made rods for full race applications.
For customers with particularly extreme requirements, we have developed our M2000 grade of steel with a tensile strength in excess of 2000 MPa and a high fatigue strength. Careful development and control of the material chemistry and heat treatment has lead to an excellent balance of mechanical properties suitable for use in the most heavily loaded race engines.
As part of the design process, we work closely with ARP to select the best available fastener for each project.
In addition to custom batch manufacture, we also hold a wide variety of rods in stock for many popular race engines, both modern and vintage.
