Manley Performance Platinum Series 85mm Bore Piston Set for Mitsubishi Eclipse GST/GSX 4G63T with Dish Design

Description

The Manley Performance Platinum Series piston set is engineered for high-performance Mitsubishi Eclipse GST and GSX models equipped with the 4G63T engine. Featuring 2618 alloy forgings sourced domestically, these pistons offer exceptional strength and durability for demanding racing and tuning applications. The set includes pistons with a dish design, optimized for compression ratios of 10.0:1 and 10.5:1, providing a balanced blend of power and efficiency. Chrome moly wrist pins are standard, with options for upgraded materials such as 9310 and Turbo Tuff/DLC alloys on select SKUs, ensuring enhanced longevity under high-stress conditions.
Precision manufacturing standards are upheld, with meticulous ring lands and grooves that promote superior ring seal for increased power output. The cam and barrel (skirt) profiles are carefully designed to generate substantial power while minimizing wear on cylinder walls. Manley’s proprietary fixturing process allows for the ring groove and skirt machining to be performed in a single operation, resulting in precise ring-to-skirt squareness and consistent performance.
This piston set is suitable for professional engine builders and serious tuners seeking reliable, high-quality components that deliver consistent performance. It is important to note that these pistons are not CARB approved and require acknowledgment of this status before installation. The set is not suitable for air freight shipping and is designed specifically for automotive use, conforming to Prop 65 regulations for safety. Engineered with attention to detail, the Manley Platinum Series pistons ensure durability and performance in high-stress racing environments, making them an excellent choice for custom builds and engine upgrades.
