Manley Mitsubishi Eclipse 85.5mm Bore 88mm Stroke 12cc DISH T/T Piston Set of 4

This set includes four forged pistons for your Mitsubishi Eclipse, featuring an 85.5mm bore, 88mm stroke, and a 12cc dish volume. These pistons are built for serious engine work, designed to handle the demands of high-performance builds where strength and reliability are paramount. They are a key component for anyone looking to rebuild or significantly upgrade their engine's internal components.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their exceptional strength and ability to perform under stress. They come standard with premium chrome moly wrist pins, and for select applications like this one, Manley offers upgrades to even more durable alloys like 9310 and Turbo Tuff/DLC for added longevity. The ring lands and grooves are machined to very strict standards, which helps ensure a better seal from your piston rings, leading to more efficient power delivery. The pistons also feature specific cam and barrel skirt profiles that are shaped to generate power while minimizing wear on your cylinder walls.

Manley's manufacturing process uses unique fixturing that allows them to machine the piston skirt and cut the ring grooves in one operation. This ensures that the ring grooves are perfectly square to the piston skirt, which is critical for proper ring seal and overall engine health. It's worth noting that these pistons are not CARB approved and cannot be shipped to California. If you're building a performance engine, these pistons are a solid choice from a well-known manufacturer in the racing world.
