Pistons Parts at Racing market for Mitsubishi-4B112.0TEVO-GEN-X has been designed to dramatically improve engine performance with increased compression unlocking the performance potential of engine.Performance Pistons Racing Pistons Automotive Engine Pistons & Motorcycle Piston Kits

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.

All  high performance JA Pistons are precision CNC machined from state of the art forgings for maximum strength and low weight. Specially developed high tensile forged aluminum has been chosen after decades of research and development, and provides incredible strength and stability under high stress conditions. All dome or dish features have smooth flowing radii and require no deburring or preparation before installation.

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.
