Manley 03-06 Evo 8/9 4G63T/4G63 85.5mm +.5mm Over Bore 10.0/10.5:1 Flat Top Pistons w/ Rings

Manley Performance is well-known for building strong engine components that professional builders trust. If you're rebuilding the engine in your 1993-1999 Mitsubishi Eclipse, 2003-2006 Mitsubishi Lancer, 1993-1998 Eagle Talon, or 1993-1994 Plymouth Laser, these forged pistons are a solid choice for enhanced performance and durability. They are designed to be 0.5mm over the standard bore size at 85.5mm, with a flat top design that results in a 10.0:1 or 10.5:1 compression ratio, depending on your cylinder head volume.

These pistons are crafted from domestic 2618 alloy forgings, a material chosen for its strength and ability to handle the stresses of performance engines. They feature proven cam and barrel skirt profiles, which help them generate power efficiently while being gentler on your cylinder walls. The ring lands and grooves are machined to strict standards to ensure a better seal for your piston rings, leading to more power. Each set includes premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the piston skirt for optimal performance.

This set includes the pistons, rings, and wrist pins. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures when rebuilding your engine.
