Description

The vision is for Kelford Cams to be known as one of the best in the camshaft industry, to be recognised worldwide for manufacturing high quality, high performance camshafts for the motorsport industry. We are a small company that, since 1968 has specialised in custom camshafts to suit the individual requirements of each racer. We have a vast knowledge of engine combinations for all types of motor sport and we know how to match camshafts to engine and vehicle requirements. All of our cams are manufactured in-house using ultra-modern design systems and ground using masterless CNC grinders with CBN cutting wheel technology for superior quality and consistency.
