Manley 03-06 Evo 8/9 (7 Bolt 4G63T) 85.5mm +0.5mm Over Bore 8.5:1 Dish Pistons w/ Rings

Starting with domestic 2618 alloy forgings, these Manley pistons are built for serious performance. They're designed for the 4G63T engine found in popular DSM platforms like the 1993-1999 Mitsubishi Eclipse, Eagle Talon, and Plymouth Laser, as well as the 2003-2006 Mitsubishi Lancer Evolution. The 85.5mm bore size, which is a +0.5mm overbore from stock, and the 8.5:1 dish volume are key specs for builders looking to optimize compression for forced induction setups.

Manley uses proven cam and barrel skirt profiles that help reduce friction and wear on your cylinder walls, even under high loads. They also machine exacting ring lands and grooves to ensure a solid seal for the piston rings, which translates directly into more power. The included wrist pins are premium chrome moly, and Manley's unique fixturing allows them to machine the skirt and ring grooves in one operation. This ensures the ring grooves are perfectly square to the piston skirt, a detail that matters for consistent performance and longevity.

This set includes the pistons, rings, and chrome moly wrist pins. Remember that these pistons are not CARB approved and cannot be shipped to California. For builds targeting high horsepower, these pistons are a solid choice, but always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
