The JE Pistons 323901S is a high-performance forged piston engineered for demanding racing and high-output engine applications. Built to JE's exacting standards, this single replacement piston delivers the strength, precision, and thermal stability required in both motorsport and performance street builds.

Key Features:

• Forged Construction: Manufactured from premium forged aluminum alloy for superior strength-to-weight ratio and fatigue resistance under high cylinder pressures
• Precision CNC Machined: Tight tolerances ensure proper fitment, ring seal, and consistent performance across all cylinders
• Advanced Skirt Coating: Low-friction skirt coating reduces wear and improves scuff resistance during initial break-in and extended use
• Single Piston ("S" Suffix): Sold individually, allowing replacement of a single unit without purchasing a full set
• Gas Ports & Ring Grooves: Engineered ring land geometry optimizes ring seal and minimizes blow-by for maximum compression retention
• Thermal Management Design: Piston crown and pin bore geometry designed to manage heat effectively under sustained high-RPM operation

JE Pistons has been a trusted name in professional motorsports for decades, supplying pistons to championship-winning teams across drag racing, road racing, off-road, and circle track disciplines. The 323901S continues that legacy of precision manufacturing and race-proven durability.
