We are the first port of call for anyone looking for pistons that push the boundaries of performance, reliability and weight. As a leader in Metal Matrix Composite piston technology, we understand how to design and manufacture pistons that can deliver exceptional results under extreme conditions.
We have demonstrated the credibility and quality of our MMC pistons at the cutting edge of industry, having been involved in a large number of projects in recent years. Our team has led extensive tooling and piston machining trials to understand fully how to extract the benefits of MMC solutions.


Working with some of the leading suppliers of advanced MMC materials, we can extend our offering in this area to provide unrivalled custom pistons and underscore the reputation on which we pride ourselves: a trusted, first-choice piston manufacturer for those wanting a performance edge. Our MMC products are designed and manufactured to be of superlative quality; higher specific modulus allows for a lighter and stiffer design, while use of significantly improved material properties at higher temperatures delivers lighter, more durable pistons.


The reinforced MMC structure minimises wear at critical interfaces, compared to more conventional piston materials, and offers a lower coefficient at thermal expansion. This, in turn, results in better control of clearances across operating temperatures. Higher thermal conductivity underscores the lighter, more reliable design features of our pistons, which are precisely the qualities that keep our customers coming back time and again for engine pistons on which they can depend.
We never stand still in pursuit of the next technological development or innovation. That ethos extends into our piston manufacturing. We have developed, over 60 years of business, an unparalleled knowledge of the interaction between piston and engine components to deliver performance without compromising weight or durability. With MMC, the overall result are pistons with an immediately superior finish to standard variants. When coupled with our innovative oval skirt profile, polished crown, anti-detonation bands, accumulator groove, profiled pin bore and Diamond Like Carbon (DLC) gudgeon pin technology, allows us to remain at the pinnacle of piston design.
