Manley 03-06 Evo 8/9 (7 Bolt 4G63T) 85.5mm +.5mm Over Bore 100mm Stroke 8.5:1 Dish Piston w/ Rings

If you're rebuilding the engine in your 1993-1999 Mitsubishi Eclipse, Eagle Talon, Plymouth Laser, or 2003-2006 Lancer, these Manley forged pistons are a solid choice for getting more out of your 4G63T engine. They're designed to handle the demands of performance builds, offering a significant step up from stock components.

Manley uses domestic 2618 alloy forgings, which are known for their strength, making these pistons well-built for high-performance applications. They feature proven cam and barrel skirt profiles that help generate power while being easier on your cylinder walls. The pistons also come with premium chrome moly wrist pins, and the ring lands and grooves are machined to strict standards to ensure a good seal, which translates to more power. Manley's unique manufacturing process ensures the ring grooves are square to the piston skirt, contributing to overall engine health and performance.

These pistons are an overbore size of 85.5mm, meaning they are 0.5mm larger than the standard bore size. They have a dish volume that results in a 8.5:1 compression ratio, which is common for turbocharged applications where you want to control detonation. Keep in mind these are not CARB approved and cannot be shipped to California.
