PPM is proud to release the product you have all been asking for! Our new range of PPM pistons compliment our existing con rod lineup and are a must for your high power engine build. Specifically designed for professional racers, our pistons are ready to cope with the stresses of high compression, high RPM and mega boost. Our engineers have combined the highest quality alloys, the very latest forging & machining technologies and then topped it all off with cutting edge coatings. The result is best pistons on the market, ready for any abuse you can throw at them.

Features:

Pistons forged from 2618 or 4032 grade aluminum alloy CNC machine pins Each piston de burred by hand Machined ring grooves for low-drag, light-weight rings Asymmetrical valve pockets Precision milling for maximum weight savings without compromising strength Anti-friction coating skirt coating reduces drag, scuffing, friction and cylinder bore wear..

Ceramic Crown Coating This coating reflects heat into the combustion chamber and away from the piston crown, while lowering piston temperatures for increased part life. The engine can experience improved combustion and performance as a result of heat being reflected back into the fuel charge.

PPM’s forged pistons skirt coating gives the dark appearance. This is a dry lubricant coating which is permanently bonded to the piston surface, as opposed to a thermal film coating which can wear off. This skirt coating provides a lubrication until the engine oil reaches operating temperature, most importantly during cold start scenarios, protecting against galling and micro-welding.
