Manley 08+ Mitsubishi Evo X (4B11T) 94mm Stroker 86.5mm +0.5mm Bore 9.0:1 Dish Piston Set with Rings

When you're building a stroker engine for your 2008-2014 Mitsubishi Lancer, the pistons are a critical component. This set from Manley Performance uses domestic 2618 alloy forgings, a material known for its strength and ability to handle the demands of a performance engine. The pistons are designed with a 9.0:1 compression ratio and a dish shape, which is important for managing combustion in a stroker setup. They also feature proven cam and barrel skirt profiles, which help reduce friction and wear on your cylinder walls while still allowing the engine to make good power.

Manley takes a precise approach to machining these pistons. They pay close attention to the ring lands and grooves, ensuring a tight seal for the piston rings. This attention to detail is crucial for maximizing power output and preventing blow-by. The unique fixturing Manley uses allows them to machine the skirt and the ring grooves in the same operation, which helps ensure the ring grooves are perfectly square to the piston skirt. This set also includes premium chrome moly wrist pins for added durability.

This piston set is designed for the 4B11T engine found in the Evo X models. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're looking to build a robust stroker engine, these Manley pistons offer a well-built foundation with a focus on performance and durability.
