Manley 93-99 Mitsu 4G63 86mm Bore 94mm Stroke 8.5 CR -17cc Dish Piston Set w/ Ring

Manley Performance is well-known for building strong engine components that serious builders trust. If you're working on a 1993-1999 Mitsubishi Eclipse with the 4G63 engine, this set of forged pistons is designed to handle the demands of a performance build. These pistons feature an 86mm bore and 94mm stroke, with a compression ratio of 8.5:1 and a -17cc dish, making them a solid choice for boosted applications where you need to control cylinder pressure.

These pistons are forged from 2618 alloy, a material chosen for its strength and ability to perform under high stress. They also feature proven cam and barrel skirt profiles, which help reduce friction and wear on your cylinder walls while still allowing the engine to make good power. The ring lands and grooves are machined to strict standards to ensure a tight seal, which is crucial for both power and efficiency. Manley's unique machining process allows them to turn the skirt and machine the ring grooves in one operation, ensuring the ring grooves are perfectly square to the skirt for optimal performance.

This set includes premium chrome moly wrist pins for added durability. While these pistons are not CARB approved and cannot be shipped to California, they represent a well-built option for enthusiasts looking to rebuild or upgrade their 4G63 engine. Make sure to check the manufacturer's installation instructions for proper fitment and assembly details.
