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.
Additional Information:
Radiused Valve Pocket for detonation resistance and increased flow around valves
Anti-detonation Grooves with the added benefit of keeping the top ring groove free of carbon
3mm oil rings for better oil control and reduced friction for more horsepower
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.
