Supertech Performance P4-DU88-P7 Forged Piston Ford Duratec CR - 88.5mm 11 1

The Supertech Performance P4-DU88-P7 is a forged high-performance piston engineered for Ford Duratec 2.0 and 2.3 engines. With an 88.5mm bore diameter (+1mm oversize), an 11:1 compression ratio, and proven construction from enhanced 4032 aluminum alloy, these pistons are built for serious street and competition builds. Matching ring set part number is R88.5-GNH8850. Sold individually — order one per cylinder.

Key Specifications:

• Bore: 88.5mm (+1mm oversize)
• Compression Ratio: 11:1
• Compression Height: 28.50mm
• Pin Diameter: 21mm
• Skirt Style: Slipper Design
• Material: Enhanced 4032 aluminum alloy (with Cu, Ni & Mg)
• Compatible Ring Set: R88.5-GNH8850

Construction & Engineering:

• Manufactured from high-silicon 4032 aluminum alloy enhanced with copper, nickel, and magnesium for low thermal expansion, excellent wear resistance, and superior thermal conductivity
• Multi-stage forging process (2 or 3 steps depending on application) produces a fine-grain structural orientation for maximum strength
• Multiple heat treatment cycles deliver high tensile strength and evenly distributed hardness throughout the piston body
• Precision CNC machining ensures flatness of ring grooves and tight dimensional tolerances
• Standard contact reduction grooves reduce friction and heat buildup
• Pin bores are honed and reamed for a precise wrist pin fit
• Chrome-moly steel wrist pins, cold-extruded for high strength, retained with wire clip locks
• Phosphate dry lubricant coating on the skirt protects rings against micro-welding and enhances lubrication in the cylinder bore

Compression ratios are calculated using a 0.030" head gasket and 0.010" deck clearance unless otherwise specified. These pistons are designed using CAD and Finite Element Analysis (FEA) software, reflecting Supertech's 40+ years of experience in high-performance piston manufacturing.

Sold per piston. Order one quantity per cylinder (e.g., quantity of 4 for a 4-cylinder engine). For the complete kit version, refer to part number P4-DU88-P7-4.
