Wiseco Pistons K0002X3 Pistons - Professional Series

The Wiseco K0002X3 Professional Series forged piston set delivers race-proven performance for high-output engines. Forged from 2618 alloy — the same material trusted in Formula 1, IndyCar (IRL), NHRA Pro Stock, and MotoGP applications — these pistons are engineered for maximum strength, durability, and power output. The set includes 8 pistons designed for a 9.750 deck height, and comes complete with pins (S643) and rings (compatible ring set: 4032GFX).

Key Features:

• 2618 Alloy Forging: High-strength aerospace-grade alloy provides superior tensile strength and thermal fatigue resistance under extreme conditions.
• Strutted Skirt Design: Reinforced strutted high-strength skirt construction reduces flex and promotes bore stability for optimum ring seal.
• Max 23 Series Platform: Purpose-built for high-performance and racing applications demanding maximum power output.
• Optimized Valve Pockets: Precision-machined valve relief designs maximize airflow around the valve, accommodating oversized valves and high-lift camshafts.
• Performance Crown Geometry: Piston crown shape promotes intake charge efficiency through improved scavenging and cross-flow during valve overlap events.
• Detonation-Resistant Dome Profile: Engineered dome geometry optimizes quench during the compression/combustion cycle, reducing susceptibility to detonation and pre-ignition for increased engine longevity.
• Precision Ring Grooves: Machined to exact tolerances with calculated groove root diameters and axial widths for maximum ring seal, reduced blow-by, and minimized oil consumption.
• ISO-Certified Forging Facility: Manufactured using advanced grain-flow alignment technology and complex forged shapes for world-class consistency and strength.
• Pins Included: Set ships with Wiseco S643 wrist pins.
• Rings Included: Ring set included; recommended ring set part number 4032GFX.

ArmorGlide Skirt Coating

Wiseco's proprietary ArmorGlide skirt coating is developed and validated through an in-house dynamometer program. This advanced polymer lubricant coating minimizes friction, improves wear resistance, and allows tighter piston-to-wall clearances compared to uncoated pistons. The tighter fit improves ring seal and reduces piston rock noise — delivering both performance and refinement in high-demand engine builds.
