Wiseco 6452RX165 Professional Series Forged Piston 2618 Alloy Stroker/Nitrous/Turbo (Right)

The Wiseco 6452RX165 is a Professional Series forged piston machined from 2618 alloy, engineered for high-demand applications including stroker, nitrous, and forced induction (turbo/supercharger) builds. This is an individual right-side replacement piston designed for engines with a 4.250-inch stroke and a 9.700–9.715-inch deck height. Rings are included, and the piston ships with pin set S643. Must be used with a K1 connecting rod. The recommended ring set is 4168GFX.

Wiseco draws on decades of motorsport development across Formula 1, IRL, NHRA Pro Stock, MotoGP, AMA Superbike, and AMA Supercross to deliver uncompromising piston technology for the street, strip, and track.

Key Features:

• 2618 Forged Alloy Construction — High-strength alloy ideal for high-heat, high-boost, and nitrous applications where durability under extreme load is critical.
• Optimized Valve Pockets — Designed to maximize flow around the valve, enabling the use of oversized valves and high-lift camshafts.
• Performance Crown Shape — Promotes maximum intake charge efficiency through scavenging and cross-flow during valve overlap for increased power output.
• Quench-Optimized Dome — Engineered for optimal quench during the compression and combustion cycle, improving resistance to detonation and pre-ignition for longer engine life.
• Precision Ring Grooves — Calculated groove root diameters and axial widths deliver superior surface finish, maximum ring seal, and minimized blow-by and oil consumption.
• ISO-Certified Forging Facility — Produced using complex forged shapes, advanced materials, and feature-aligned grain flow technology for world-class consistency.
• Complex Skirt Profile — Reduces friction while maintaining bore stability for optimal ring seal throughout the RPM range.

ArmorGlide Skirt Coating

This piston features Wiseco's ArmorGlide dry-film skirt coating, developed through rigorous in-house dyno testing. ArmorGlide minimizes friction, maximizes horsepower, and improves wear resistance. The coating also allows the piston to be fitted tighter within the bore than an uncoated piston, reducing piston rock and noise while improving ring seal.
