Manley High-Performance Forged Piston Mitsubishi Dish

Manley High-Performance Forged Pistons with a dish design are built for Mitsubishi 4G63 and 4G63T engine builds. They suit builders who want forged engine pistons that hold up under boost, nitrous and other power-adder setups. This line is part of Manley's Platinum Series. Each piston is forged from 2618 alloy, which offers strong, fatigue-resistant performance at high temperatures.

Key Features:

• 2618 alloy forgings give high strength with a lightweight design.
• Contour forgings balance strength and weight without internal milling that would interrupt the grain structure.
• Dish piston face lowers compression, which helps in forced-induction builds.
• Cam and barrel skirt profiles are designed to make good power while staying gentle on cylinder walls.
• Offset wrist pin design is intended to keep cold start-ups quiet.
• Machined ring grooves use a multi-step top-ring groove process that controls groove size, geometry, flatness and finish for better ring seal.
• Single-fixturing machining cuts the skirt and ring grooves in one setup, which keeps the ring grooves square to the skirt.
• Pressure balance groove and precision pin fitting are included on select part numbers.
• Wrist pins and locks: chrome moly or tool steel wrist pins and round wire locks come with the pistons, depending on the part number.
• Skirt coating: moly-coated skirts are available on select part numbers to improve durability.
