Arrow Precision manufacture components of exceptional quality in an industry known for its exacting standards. Our components will out-last those of the competition and out-perform them as well, representing excellent value for money. Arrow Precision Engineering designs strength in and pays attention to the details: the only way to get a lightweight, robust rod and real quality.

We manufacture from the highest quality steel, specified and purchased by us, from mills in the UK. Vacuum de-gassed nickel chrome alloy steel (Double-air-melt) has a very low sulphur content, .025%, which means fewer inclusions and faults. When forged, imperfections are reduced to an absolute minimum, ensuring excellent consistency in the seven standard forgings reaching our machine shop.

Before the machining process can begin a detailed drawing of the connecting rod is sent out for your approval. A tensile and reciprocating load analysis will have been carried out and the design produced with the help of our unique CAD programme, drawing details include material spec, bushing requirements, special machining needs and, of course, dimensions and fastener types. Once you have ensured the spec meets with your requirements, your order will be scheduled in our machine shop and a firm delivery date given and achieved. Our engineer will then write the machine plan including the selection of raw materials. One to hundreds of quality rods can be produced using flexible manufacturing lines and unique processes.

During production all facets of the forgings are machined to ensure symmetry and balance, but also to remove any potential flaws. Having been split, the big end is then torqued up using slave bolts. We work closely with our fastener supplier ARP to ensure the correct bolt is selected for each design, pointing out the importance of attaining correct stretch in each fastener (please see our 'Hints and Tips' booklet). Once the CNC operations are completed, the rod is rumbled and peened to ensure uniformity of finish and surface hardness, and the correct bolts are then fitted. The rods are finish ground and balanced end to end, to within a gram.

On each operation a recorded sample inspection is carried out. Our Magnaflux crack detection unit tests all our rods in our specially constructed dark room.
Prior to despatch a full sample inspection and 100% visual will be undertaken. The adherence to ISO 9002 enables us to monitor all materials and processes from beginning to end, guaranteeing an excellent product.

Finally and uniquely, every rod produced is laser etched with the company logo, but more importantly, with a date of manufacture, a part designation and a set number. Many manufacturers mark their products with a stamp: not only can this be hard to read but it can also harm the integrity of the item. Just another reason to buy Arrow Precision.

We can manufacture H beam and I beam section rods and are happy to talk to anyone with an interest in purchasing the best there is . . . . . . . Our steel rods have been successful in World Rally cars, Le Mans series, F3, Touring Cars, F3000 and used by British Luxury and Sports Car manufacturers, our Titanium rods have been in competition all over the world in Ducatis and Hondas.
