Manley Sport Compact Platinum Series Pistons – Precision & Performance

Manley Platinum Series pistons are crafted from high-strength 2618 forged aluminum alloy, designed to handle extreme temperatures and high cylinder pressures. Ideal for high-performance and boosted applications, these pistons offer the ultimate balance of strength, durability, and lightweight construction.

Machined with one-fixturing technology, each piston maintains perfect ring groove-to-skirt squareness, ensuring optimal sealing and maximum horsepower.
