About this part

Product Details

If you're rebuilding the engine in your Mitsubishi Lancer Evolution with the 2.0L 4B11T engine, this Manley Performance Piston Set is a solid choice for serious performance. These aren't just stock replacements; they're built from the ground up for engines that demand more power and durability than factory parts can handle. Manley has been a go-to for professional engine builders for a reason, and this set is designed to meet those high standards.

What sets these pistons apart starts with the material: they're forged from 2618 alloy, a domestic material known for its exceptional strength and ability to withstand the high pressures and temperatures found in performance engines. They feature proven cam and barrel skirt profiles, which help reduce friction and wear on your cylinder walls while still allowing the engine to make substantial power. The ring lands and grooves are machined to very strict tolerances, ensuring a tight seal with your piston rings for improved compression and power output. Each set also includes chrome moly wrist pins, which are strong and reliable for performance applications.

When you're building an engine that needs to perform, details matter. Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single setup. This ensures that the ring grooves are perfectly square to the piston skirt, which is critical for optimal ring seal and overall engine health. This attention to detail means you're getting a well-built component that's ready for the demands of a performance build.
