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)
Tighter tolerances on 14 critical areas of the piston
Low noise materials
Custom piston:JAmodifed can produce pistons for almost all engines. If the parts you need are not within our standard, or you need pistons with different configurations, please fill in the CUMSTOM FORM and check PISTON CATALOG, we will have a design engineer to measure for you Customized.
