Manley 03-06 EVO VIII/IX 85mm STD Bore 8.5:1 Dish Piston Set with Rings

Manley Performance is well-known for building strong engine components that professional builders trust. If you're working on a 1993-1999 Mitsubishi Eclipse, 2003-2006 Mitsubishi Lancer, or the related Eagle Talon and Plymouth Laser models, this set of 85mm standard bore pistons is designed to handle serious performance builds. These aren't just any pistons; they're forged from 2618 alloy, a material chosen for its exceptional strength and ability to withstand high stresses, making them a solid choice for enthusiasts looking to push their engine's limits.

What sets these pistons apart is their thoughtful design, which balances power with durability. They feature proven cam and barrel skirt profiles that help reduce friction and wear on your cylinder walls while still generating substantial power. The ring lands and grooves are machined to very precise standards, which is critical for ensuring a good seal between the piston rings and the cylinder wall. This improved seal means better compression and more efficient combustion. Manley also uses unique fixturing during manufacturing, allowing them to machine the skirt and ring grooves in one operation. This ensures the ring grooves are perfectly square to the piston skirt, contributing to overall engine health and performance.

This set includes premium chrome moly wrist pins, which are strong and reliable for many applications. For those building a high-output engine, Manley offers upgrades to even stronger wrist pin alloys. This piston set is designed for an 8.5:1 compression ratio with a dish-style piston, which is a common target for turbocharged or supercharged applications where you need to control detonation. Remember, 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.
