• Crown design – intruder, flat op or bowl style crow to suit either port or direction injection
  • Optimised undercrown design – Single prong or fully formed undercrown designs provide increased strength, durability and minimised piston mass
  • Profiled pin bore – To improve gudgeon pin reliability
  • XYLAN/DLC coated skirt – To reduce fiction on piston skirt thrust faces
  • Skirt scroll – Unique design to aid oil retention
  • Gas Control features – Gas ported top ring and accumulator groove. To reduce blow by and aid sealing under high cylinder pressures

We produce over 40,000 forgings and 20,000 fully machined pistons p.a. to our customers’ designs. In our dedicated piston facility, our pistons are made to the highest quality levels (and often to tight deadlines) from forgings, machined billet 2618, 4032 or MMC.

From full clean sheet design, to engineering, testing and validation – we support the full piston development cycle. Our reciprocating component design process ensures that piston and con rod designs work in harmony. Honing our expertise in engineering using the latest in 3D technology allow us to refine and improve on existing designs.

Our pistons are utilised in a huge variety of different forms of motorsport. From the highest level of international car and motorcycle racing to historic and club level motorsport, our piston customers have won countless races and championships.

Additionally, we work with major OEM customers designing and manufacturing pre-production prototype pistons in a variety of batch sizes. Typically these pistons are machined from billet to allow rapid testing of alternative skirt profiles, crown designs and other features.

With full traceability from raw material to finished piston, every Cosworth piston is produced to the highest quality and then laser etched for ease of identification. We rigorously adhere to ISO9001 and AS9100 quality standard and operate a fully audited supply chain. We also offer NDT and CMM inspection in-house.
