Wiseco RED0103X4 Forged Piston Dish Bore Ford - 12cc 4.040

The Wiseco RED0103X4 is a forged performance piston from Wiseco's Redline series, designed for Ford applications requiring a 4.040-inch bore diameter. Featuring a -12cc dish top, this piston is engineered to provide a controlled compression ratio, making it well-suited for naturally aspirated, turbocharged, or supercharged Ford V8 builds where detonation resistance is a priority.

Key Features:

• Bore Diameter: 4.040 inches — a common overbore size for Ford small-block and big-block V8 engines
• Compression Height (Pin Height): 1.090 inches for precise deck clearance tuning
• Dish Volume: -12cc dish top to reduce effective compression ratio
• Forged Construction: CNC-machined from aerospace-grade forged aluminum for superior strength-to-weight ratio
• Wiseco Redline Series: Built for high-performance street and competition engine applications
• Skirt Coating: ArmorGlide skirt coating reduces friction and improves durability
