Manley Mitsubishi Eclipse GS/GST/GSX 85.5mm +0.5mm 8.5:1 -12cc Extreme Duty Dish Pistons w/ Rings

If you're rebuilding the engine in your Mitsubishi Eclipse GS, GST, or GSX and pushing the limits, these Manley Extreme Duty Dish Pistons are built to handle serious power. They're designed for high-performance applications where reliability under stress is paramount. These pistons are forged from a domestic 2618 alloy, a material known for its exceptional strength and durability, making them a solid choice for boosted or high-compression builds.

Manley uses proven cam and barrel skirt profiles on these pistons. This design helps them run smoothly against the cylinder walls, reducing wear and noise while still allowing for substantial power output. The ring lands and grooves are machined to very strict standards, which is crucial for getting a good seal from your piston rings. A good ring seal means better compression, more power, and less oil getting into the combustion chamber. These pistons also come with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the piston skirt for optimal performance.

This set includes the pistons, rings, and wrist pins, ready for installation. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a build that demands robust internal components, these Manley pistons offer the strength and precision needed to achieve your performance goals.
