Manley Mitsubishi 4G63/4G63T 87mm Bore (+2.0mm) -8cc Dome Extreme Duty Dish Pistons w/ Rings

Manley Performance is well-known for building strong engine components, and their Extreme Duty Dish Pistons for the Mitsubishi 4G63 and 4G63T engines are a prime example. If you're rebuilding the heart of your performance Mitsubishi, these pistons are designed to handle serious power and deliver reliable performance over the long haul. They feature an 87mm bore with a +2.0mm overage and a -8cc dish, which is a common setup for many performance builds.

These pistons are forged from 2618 alloy, a material chosen for its exceptional strength and ability to withstand high temperatures and pressures found in demanding engine applications. Manley uses proven cam and barrel skirt profiles, which help reduce friction and wear on your cylinder walls while still allowing the piston to generate substantial power. The ring lands and grooves are machined to exacting standards, ensuring a tight seal for improved combustion efficiency and more power output. For added durability, these pistons come standard with premium Chrome Moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, which is critical for proper sealing and longevity.

This set includes the pistons, rings, and wrist pins, making it a comprehensive solution for your engine build. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're looking for a well-built, durable piston set for your 4G63 or 4G63T engine, Manley's Extreme Duty line is a solid choice that professional engine builders trust.
