About this part

Product Details

Starting with a 2618 alloy forging, Manley's Platinum Series piston is built for strength in your Chevy Small Block engine. This piston features a passenger side bore and a -18cc dish, designed to work with specific engine builds. The use of domestic 2618 alloy is key here, offering a well-built foundation for performance and durability.

Manley pays close attention to the details that make a difference. You'll find exacting standards for the ring lands and grooves, which helps ensure a better seal for more power. The cam and barrel skirt profiles are also notable; they're shaped to generate power while being easier on your cylinder walls. Plus, their unique fixturing process allows them to machine the skirt and ring grooves in one go, making sure the ring groove stays square to the skirt for a more consistent seal.

This piston comes standard with premium chrome moly wrist pins, and depending on the specific part number, you might even have options for upgraded wrist pin alloys for even more durability. Keep in mind this part is not CARB approved and cannot be shipped to California.
