Details
JA piston feature a unique PTFE coating on the skirts and a grade of 4032 Alloy (T6) which allows the engine builder to run a closer piston to bore tolerance . This helps remove the slapping noise during cold start, common place among engines running forged pistons due to larger then OE bore clearances.
The crowns of the pistons are also polished to better resist detonation on a high performance engine. Polishing allows a more even spread of heat inside the chamber which will help prevent “hot spots” on piston crowns.
Additional Information：
Lightweight design（the shortened wrist pins reduces the overall weight,increased stability and strength)
Low noise materials
Ultra flat ring grooves for ring seal promotion
