Manley 03-06 Mitsubishi Evo 8/9 4G63T 86.5mm +1.5mm 8.5.0/9:1 Dish 100mm Stroke Pistons w/ Rings

If you're building a high-performance engine for your Mitsubishi Eclipse, Evo 8/9, or other compatible vehicle, these Manley 86.5mm forged pistons are a solid choice. They're designed to handle the demands of boosted applications and serious engine work, offering a significant upgrade over stock components. The dish volume creates a compression ratio around 8.5:1 to 9:1, making them suitable for forced induction setups where you need to control detonation.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to withstand high temperatures and pressures. They feature 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 strict standards, ensuring a tight seal for improved combustion efficiency and more power output. Each set comes with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt for optimal performance.

This set includes the pistons, rings, and wrist pins, making it a comprehensive package for your engine build. While these pistons are built for performance, remember they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
