Supertech Performance P4-DU875-P7 High Performance Forged Piston

The Supertech Performance P4-DU875-P7 is a precision-engineered forged piston designed for high-performance and forced induction applications. Manufactured from extruded 4032 aluminum alloy enhanced with additional copper, nickel, and magnesium, this piston offers low thermal expansion, excellent wear resistance, and superior thermal conductivity. Supertech pistons using this advanced alloy have successfully withstood boost pressures up to 42 psi with alcohol fuel without failure.

Key Features:

• Enhanced 4032 aluminum alloy with Cu, Ni, and Mg additives for improved strength and heat resistance
• Two or three-step forging process creates fine structural grain for maximum durability
• Multiple heat treatments ensure high tensile strength and evenly distributed hardness
• Precision-machined on state-of-the-art CNC equipment for exact tolerances
• Contact reduction grooves standard for optimized performance
• Honed and reamed pin bores for precise wrist pin fitment
• Cold extruded chrome moly steel wrist pins with wire clip locks included
• Phosphate dry lubricant coating protects rings against micro-welding and enhances cylinder lubrication

Compression ratios are calculated using a 0.030" head gasket and 0.010" deck height unless otherwise specified. This piston is sold individually—please order the appropriate quantity for your engine configuration (e.g., quantity of 4 for a 4-cylinder engine).
