About this part

Product Details

If you're rebuilding the engine in your 1993-1999 Mitsubishi Eclipse, 1995-1999 Galant, or 2003-2006 Lancer, these Manley Performance "Platinum Series" pistons are a solid choice. They're designed to handle the demands of a performance build, offering improved strength and reliability over stock components. This set features an 87.0mm bore with a +0.5mm oversize, suitable for engines that have been bored out to accommodate larger pistons during a rebuild.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their superior strength and ability to withstand higher cylinder pressures and temperatures. The pistons come with proven cam and barrel skirt profiles that help manage power output while being gentler on your cylinder walls, reducing wear over time. You'll also find exacting standards applied to the ring lands and grooves, which is crucial for achieving a good seal and maximizing power. The set includes premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, contributing to overall engine health and performance.

This set is designed for an 8.5/9.0:1 compression ratio with a dish-style piston top. It's important to note 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.
