• File-fit rings included, allowing custom ring end-gap sizing for your specific application
• Low-friction PVD-coated skirts reduce parasitic drag and improve longevity

JE Pistons 300174S is built for enthusiasts and racers who demand precision-engineered components that can withstand the rigors of forced induction, nitrous, or naturally aspirated high-RPM builds. Always verify bore size, compression ratio, and ring specifications with your engine builder prior to installation.
