Wiseco 6452LX165 Professional Series Forged Piston 2618 Alloy Stroker/Nitrous/Turbo (Left)

The Wiseco 6452LX165 is a Professional Series forged replacement piston engineered for high-stress performance applications including stroker, nitrous, and turbocharged builds. Forged from 2618 alloy, this individual left-side piston is designed for 4.250" stroke engines with a 9.700"/9.715" deck height. Rings are included, and it requires Wiseco pin S643 and must be used with a K1 connecting rod. The recommended ring set is 4168GFX.

Wiseco draws on decades of race-proven engineering from the world's most demanding motorsport platforms — including Formula 1, IndyCar, NHRA Pro Stock, MotoGP, AMA Superbike, and AMA Motocross/Supercross — to deliver pistons built to withstand extreme cylinder pressures and heat cycles.

Key Features:

• 2618 Alloy Forging: High-strength alloy preferred for boosted and power-adder applications, offering superior fatigue resistance under elevated temperatures and cylinder pressures.
• ArmorGlide Skirt Coating: Wiseco's proprietary dry-film lubricant reduces friction, improves wear resistance, and allows for tighter bore fitment for better ring seal and reduced piston rock noise.
• Optimized Valve Pockets: Precision pocket geometry maximizes airflow around the valve, accommodating oversized valves and high-lift camshafts.
• Performance Crown Design: Crown shape promotes maximum intake charge efficiency through scavenging and cross-flow during valve overlap events, supporting increased power output.
• Anti-Detonation Dome Profile: Engineered for optimal quench during the compression/combustion cycle to resist detonation and pre-ignition, extending engine life.
• Precision-Machined Ring Grooves: Calculated groove root diameters and axial widths ensure excellent surface finish, maximum ring seal, and minimized blow-by and oil consumption.
• Complex Skirt Profile: Reduces friction while maintaining bore stability for consistent ring seal under race conditions.
• ISO-Certified Forging Facility: Manufactured using advanced forging technologies with feature-aligned grain flow for maximum structural integrity.
