Arrow Precision split crank application one-piece rods are second to none. We are pleased to have rods in Speedway Grand Prix machines, Grass Track and World Karting, winning at the highest levels week in week out! Our design team will help you improve on an existing rod or come up with alternative solutions that will improve performance.

Our engineers aim to lighten the steel rod but retain it's strength. There are two types of non-split rod available, each requiring different materials and heat treatment processes. If your design has liners in the big end and a bronze floating small end, our EN24 nickel chrome forgings will be used. For an unlined version, carburised steel is required and the con rod is heat treated only in necessary areas to 62 rockwell C. This design has greater benefits; it’s as strong as a lined rod but 20% lighter.

With our flexible production planning we are able to manufacture variable quantities, from a one-off experimental design to hundreds of identical rods, e.g. for use in sealed gokart race engines. As a customer you benefit from our years of experience. Whether manufacturing a tried and tested design where consistency is all, or revolutionising the internal combustion engine, we can help!

If you are wanting ultra high performance from a single cylinder, Arrow make the rod for you!
