WISECO K120A3 Ford 2300 Flat-Top Forged Piston Set, 3.810 in Bore

Upgrade your Ford 2300 engine with the WISECO K120A3 forged piston set, engineered for dependable performance in demanding street, racing, and performance applications. This set includes four flat-top pistons designed for the Ford 2300 platform, providing a strong and consistent foundation for engine builds that require durable components and precise fitment. The flat-top design supports flexible compression planning while maintaining a proven configuration for naturally aspirated and other performance-oriented applications.
The WISECO K120A3 pistons feature a 3.810 in bore size and a 1.590 in compression height, allowing builders to match the piston assembly to the intended cylinder, connecting rod, and crankshaft combination. Forged construction delivers enhanced strength and durability compared with standard cast piston designs, making these pistons well suited for engines exposed to increased cylinder pressure and higher operating loads. Always verify bore preparation, deck height, rod length, compression ratio, and clearance requirements before installation.
Each piston uses 1/16 in, 1/16 in, and 3/16 in ring grooves for compatibility with the appropriate ring package. The design incorporates a minus 3.40 cc volume specification to support accurate compression-ratio calculations during engine assembly. As a genuine WISECO component, part number K120A3 is built for performance-focused Ford 2300 applications and should be installed by a qualified engine builder using the manufacturer’s recommended procedures, clearances, and ring-fitting guidelines.
