Manley 618005C-4 Mitsubishi 85.5mm Dish Pistons - 1.248 Compression Distance

Engineered by Manley Performance—a trusted name in high-performance engine components—these pistons are built for durability and precision in demanding applications including street performance, road racing, and forced induction builds.

The dish-top dome configuration reduces the compression ratio, making these pistons especially well-suited for turbocharged and supercharged Mitsubishi engine applications where lower static compression is required to support elevated boost pressures. Each piston is manufactured to exacting tolerances to ensure consistent ring seal, thermal stability, and long-term reliability under high heat and pressure conditions.

Key Features:

• Bore Size: 85.5mm
• Compression Distance (CD): 1.248 inches
• Dome Style: Dish top — ideal for boosted applications
• Application: Mitsubishi engines
• Forged construction for superior strength and heat resistance
• Manufactured by Manley Performance — a leader in racing and high-performance engine parts
• Designed to work with OEM and aftermarket connecting rods and ring packages

Manley Performance has been a cornerstone of motorsports engine building for decades, producing pistons, connecting rods, valvetrain components, and more trusted by professional racers and engine builders worldwide. The 618005C-4 delivers the precision fitment and performance integrity that Manley is known for.
