Manley 03-06 Evo 8/9 (7 Bolt 4G63T) 86.5mm +1.5mm Over Bore 9.0:1 Dish Pistons w/ Rings

If you're rebuilding the engine in your 1993-1999 Mitsubishi Eclipse, 1995-1999 Galant, or 2003-2006 Lancer, these Manley 86.5mm +1.5mm over bore dish pistons are a solid choice. They're built with a 9.0:1 compression ratio, making them suitable for a wide range of performance applications where you need a bit more boost than stock but still want reliable street manners.

Manley uses domestic 2618 alloy forgings for these pistons, which means they're strong and can handle the heat and pressure of a performance engine. The pistons feature proven cam and barrel skirt profiles designed to be gentle on your cylinder walls while still generating power. You'll also find exacting standards for the ring lands and grooves, which helps ensure a better seal for your piston rings, leading to more efficient combustion and improved power output. They come with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the piston skirt, a detail that matters for long-term durability and consistent performance.

This set includes the pistons, rings, and wrist pins, making it a comprehensive package for your engine build. 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.
