About this part

Product Details

This Manley Extreme Duty Piston Set includes four forged pistons, tool steel wrist pins, and piston rings, ready for your 2003-2006 Mitsubishi Lancer Evolution VIII or IX. These pistons are designed for builders looking for serious performance and durability under demanding conditions. The 85.5mm bore size and the -8.5 to -9.0 compression dish are specific to certain engine builds, so make sure this matches your project's needs.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to handle high performance. The pistons feature proven cam and barrel skirt profiles, which help generate power while also being gentle on your cylinder walls during operation. You'll also find exacting standards applied to the ring lands and grooves, which is crucial for a good seal and maximizing the power your engine makes. The included tool steel wrist pins are a solid choice for durability, and Manley's unique manufacturing process ensures the ring grooves are perfectly square to the skirt, contributing to overall engine health and performance.

This set is not CARB approved and cannot be shipped to California. If you're rebuilding the top end of your EVO's engine for high performance, these pistons are a well-built option from a popular manufacturer.
