Heritage automotive 👇

In order to create the future you must first respect the past: we offer modernised or sympathetic component recreations for the most respected of engine restorers.

Original parts are carefully inspected and measured before being recreated in CAD software whilst capturing any alterations the customer may require, we use additive manufactured parts to check that the fit and function meet the rigorous requirements of the customer.

Connecting rods are produced from 6 different standard forgings, all unique to Arrow Precision including a 24” long nickel chrome steel forging specifically designed for heritage applications. Crankshafts can be manufactured from period and modern forgings or a solid billet of our own specification 722M24 nitriding steel. Aerospace grade steels are sourced for those customers looking to significantly increase the performance and longevity of their engine.

White metal bearings belong to a different era of engine design👇

But in the right application, they still belong.

In this podcast snippet, Noel from our design team discusses heritage connecting rod manufacture and how Arrow can design sympathetically around traditional white metal bearing arrangements rather than automatically converting to modern shell bearings.

It is a balance of preservation and performance.

Respect the original concept. Improve where appropriate. Manufacture without compromise.

Heritage engineering, refined by modern precision.

CMM Part 2: Half a micron.

This is what unrivalled looks like.

Our new CMM is calibrated to measure within half a micron.

Some of our smallest connecting rod tolerances are 10 microns: A human hair is roughly 100 microns.

That is the level of accuracy behind every Arrow component.

Not estimated. Not assumed. Measured.

Become unrivalled.

Investment in precision is never optional

The latest addition to the Arrow facility strengthens our inspection capability with high-speed, high-precision measurement, helping us push quality, repeatability and control even further.

Another upgrade behind the scenes. Another reason Arrow remains unrivalled.
