About this part

Product Details

If you're rebuilding the engine in your 1995-1999 Mitsubishi Galant, especially if you're using a 4G63 head on a 4G64 block, this single piston from Manley Performance is a solid option. It's a standard bore size at 86.5mm with a compression ratio of 8.5:1, designed to fit right in place of your original piston.

Manley uses their well-known 2618 alloy forgings for these pistons, which means they're built strong and can handle the demands of an engine build. They also feature proven cam and barrel skirt profiles, which help the piston move smoothly in the cylinder wall while still generating power. The ring lands and grooves are machined to strict standards, aiming for a better seal from your piston rings, which translates to more power. Each piston comes with premium chrome moly wrist pins.

This piston is sold individually, so you'll want to order the correct number to match your engine's cylinders. Remember, this part is not CARB approved and cannot be shipped to California.
