JE Pistons 325022S FSR Forged Piston - Set

The JE Pistons 325022S is a high-performance forged piston set engineered for demanding motorsport and high-output engine builds. JE Pistons is a globally recognized leader in forged piston technology, manufacturing components to exacting tolerances for race, street performance, and OEM applications.

Built from aerospace-grade forged aluminum alloy, these pistons deliver the strength, heat resistance, and dimensional stability required for forced induction, nitrous, and naturally aspirated high-compression applications. The FSR (File-Fit Sport Ring) design provides a refined ring land geometry that optimizes ring seal and minimizes blow-by for improved power output and oil control.

Key Features:

• Forged aluminum alloy construction for superior strength-to-weight ratio
• Precision CNC-machined to tight tolerances for consistent fitment
• FSR (File-Fit Sport Ring) groove design for optimized ring seal
• Accumulator groove reduces ring flutter and improves combustion sealing
• Lateral gas ports available to enhance ring seal at high RPM
• Coated skirt option reduces friction and improves wear resistance
• Designed for high-compression, forced induction, or nitrous applications
• Manufactured in the USA to JE's exacting quality standards

The JE Pistons 325022S is ideal for engine builders seeking a proven, race-proven forged piston solution. As with all JE FSR pistons, proper piston-to-wall clearance should be established per JE's published specifications for the intended application.
