Manley High-Performance Forged Piston Alloy

Manley High-Performance Forged Pistons are engine pistons for street performance, racing, and high-horsepower builds. Forged from a high-strength aluminum alloy, these forged pistons are made to hold up under the heat, cylinder pressure, and rpm of modified and forced-induction engines. Builders choose Manley when they want a piston that resists detonation and stress better than a stock cast piston.

Key Features:

• Forged aluminum alloy construction gives high strength and fatigue resistance compared with cast pistons
• Built for high-performance use in naturally aspirated, turbocharged, supercharged, and nitrous-assisted engines
• Precision machined for consistent dimensions and dependable ring and wrist pin fit
• Designed for durability under sustained high load, heat, and rpm
• Many applications available, with each variant listed under its own part number
