Wiseco Pistons K120A3 Ford 2300cc Forged Piston Kit 4.000" Stroke

The Wiseco K120A3 forged piston kit is engineered specifically for Ford 2300cc engines with a 4.000" stroke. Manufactured from premium 2618 alloy, these pistons feature a 340/360 nitrous dome design for extreme performance applications. This set includes 4 pistons with pins (S489) and utilizes a slipper skirt design to reduce weight while maintaining strength.

Key Specifications:

• 2618 forged aluminum alloy construction for superior strength and heat resistance
• 340/360 nitrous dome configuration optimized for forced induction
• Designed for 4.000" stroke crankshafts
• Slipper skirt design reduces reciprocating weight and friction
• Includes wrist pins (S489)
• Must be used with K1 connecting rods
• Requires ring set 3810A (sold separately, 4 sets required)

Wiseco Performance Features:

• Precision valve pocket designs allow maximum airflow and accommodate oversized valves and high-lift camshafts
• Crown geometry engineered to promote optimal intake charge efficiency through cross-flow scavenging during valve overlap
• Dome design creates ideal quench zones for resistance to detonation and pre-ignition
• CNC-machined ring grooves with precise accumulator volume and groove geometry ensure maximum ring seal and minimize blow-by
• Complex skirt profiles reduce friction while maintaining bore stability for superior ring seal
• ISO-certified forging process with feature-aligned grain flow technology

ArmorGlide Skirt Coating:

Select Wiseco pistons feature ArmorGlide, an advanced skirt coating developed through extensive dyno testing. This high-tech lubricant reduces friction for maximum horsepower while improving wear resistance. ArmorGlide allows tighter piston-to-bore clearances than uncoated pistons, resulting in better ring seal and reduced piston noise.

Wiseco draws on decades of experience in Formula 1, IndyCar, NHRA Pro Stock, MotoGP, AMA Superbike, and Motocross to manufacture the highest quality pistons for serious engine builders and racers.
