CP has built a reputation for high end, quality pistons. These pistons have been designed to perform and keep performing at the highest levels of motorsport. They are recognised as a technological leader in piston design development for all avenues of racing.

Made in USA.

Features:

Anti-Detonation Grooves: The grooves protect the top ring by disruption detonation waves. Also known as contact reduction grooves, these limit the piston/cylinder contact during high temperature and RPM.

Accumulator Groove: This is a V shaped groove machined in the 2nd ring land to collect excess blow-by between the top and second ring. This collects residual gasses during combustion and alleviates top ring flutter while increasing ring seal.

CP Groove: This stands for constant pressure groove. This groove works as a channel on the lower part of the top land that equalises pressure to the back of the top ring groove. When used in combination with lateral gas ports, the CP groove helps keep gas port clear of carbon build up. In addition, the CP Groove prevents the top land from smudging into the top ring if the land rubs the cylinder bore.

Double Pin Oilers: These are using in conjunction with the dual fed reservoir add twice the amount of oil from the cylinder wall to the wrist pin.

X-Forgings: X-Forgings as designed to minimise friction and reduce weight with compromising strength. With the use of bracing and ribs, the forging is configured by adjusting the weight balance between high and low stress areas. This design enables the use of a short pin for added strength and weight savings.

Radius Domes: Radius Domes are used to maximise quench while elimination possible hot sports that promote detonation.

Cam and Barrel: CP have done extensive research and development to find the optimum skirt shape for each piston. Having the correct cam and barrel on a part promotes the following; tighter clearances, less noise, better ring seal, more power and better durability.
