Wiseco K243A100 Forged Piston Kit with ArmorGlide Skirt Coating

The Wiseco K243A100 is a precision forged piston engineered to deliver maximum performance and durability. Wiseco draws on decades of motorsport expertise across Formula 1, Indy Racing League (IRL), NHRA Pro Stock, MotoGP, AMA Superbike, AMA Motocross, and Supercross to produce some of the highest-technology pistons available on the market today.

Manufactured at a world-class, ISO Certified forging facility, this piston features complex forged shapes, advanced materials, and feature-aligned grain flow technology for superior strength and consistency.

Key Features:

• Valve Pocket Design: Engineered to maximize airflow around the valve, while accommodating oversized valves and high-lift camshafts.
• Optimized Piston Crown: Promotes maximum intake charge efficiency through scavenging and cross-flow during intake and exhaust valve overlap — increasing fuel and air delivery for more horsepower.
• Detonation-Resistant Dome: Designed for optimal quench during the compression and combustion cycle, resisting detonation and pre-ignition for longer engine life and increased power potential.
• Precision-Machined Ring Grooves: Calculated groove root diameters and axial widths provide an excellent surface finish, maximum ring seal, and minimized blow-by and oil consumption.
• Complex Skirt Profile: Reduces power-robbing friction while maintaining bore stability for optimum ring seal.
• ArmorGlide Skirt Coating: Wiseco's proprietary ArmorGlide coating minimizes friction, maximizes horsepower, and improves wear resistance — validated through in-house dyno testing and development.

About ArmorGlide: ArmorGlide is more than just a high-tech lubricant — it also allows the piston to be fitted more tightly within the bore compared to non-coated pistons. This tighter fit improves ring seal and reduces piston rock noise for a quieter, more efficient engine.

Wiseco's forged pistons represent the gold standard in performance engine components, trusted by professional racers and serious enthusiasts worldwide.
