Manley 03-06 EVO VIII/IX 85mm STD Bore 8.5:1 (Extreme Duty) Dish Piston Set with Rings

If you're rebuilding the engine in your 2003-2006 Mitsubishi Lancer Evolution for serious performance, a strong set of pistons is where you start. These Manley Performance "Platinum Series" pistons are built for extreme duty, meaning they can handle the demands of a high-output engine. They feature a dish design and a standard 8.5:1 compression ratio, making them a solid choice for boosted applications 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. The skirt profiles are carefully shaped to reduce friction and wear on your cylinder walls while still generating power. You'll also find exacting standards for the ring lands and grooves, which are crucial for a good seal and maximizing the power your engine makes. These pistons come with premium chrome moly wrist pins, and Manley's unique machining process ensures the ring grooves are perfectly square to the skirt for optimal performance.

This set includes the pistons, rings, and wrist pins needed to get your engine back together. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance Evo engine, these Manley pistons are a well-built component that professional builders trust.
