Manley 03-06 Evo VII/IX 4G63T 86.5mm +1.5mm Oversize Bore 10.0/10.5:1 Dish Piston Set with Rings

Manley Performance is well-known for building robust engine components that stand up to serious use. If you're rebuilding the engine in your 2003-2006 Mitsubishi Lancer Evolution VII or IX, this set of 86.5mm +1.5mm oversize forged pistons is a solid choice. These pistons are designed to handle the demands of a performance 4G63T engine, offering improved strength and reliability over stock components.

Crafted from domestic 2618 alloy forgings, these pistons are built for superior strength and performance. They feature proven cam and barrel skirt profiles, which help generate substantial power while being gentle on your cylinder walls. Manley also pays close attention to the details, ensuring exacting standards for ring lands and grooves to achieve enhanced ring seal and ultimately, more power. The included wrist pins are premium Chrome Moly, and Manley's unique fixturing process ensures ultimate squareness between the piston skirt and ring grooves, a critical detail for engine longevity.

This set is designed for a 10.0/10.5:1 compression ratio with a dish top, and it comes complete with rings and tool steel wrist pins. These pistons fit a range of vehicles, including the Mitsubishi Eclipse, Eagle Talon, and Mitsubishi Lancer, making them a versatile option for many performance builds.
