About this part

Product Details

These Manley Chevrolet LS pistons start with domestic 2618 alloy forgings, a material chosen for its exceptional strength and ability to handle high performance demands. The 4.005-inch bore size and 1.115-inch compression height, combined with an -18.00cc dish volume, are specific dimensions that engine builders select for particular compression ratio targets in LS engines.

Manley builds these pistons with proven cam and barrel skirt profiles, which are designed to generate substantial power while also being gentle on your cylinder walls, reducing wear over time. The ring lands and grooves are machined to exacting standards, which is crucial for achieving a solid ring seal and maximizing the power your engine can produce. For added durability, these pistons include premium chrome moly wrist pins, and Manley's unique fixturing process allows for skirt turning and ring groove machining in a single operation, ensuring ultimate squareness between the ring groove and the skirt.

This set is a popular choice among professional engine builders and tuners who rely on Manley pistons for both superior performance and long-term durability in demanding applications. Please note that these pistons are not CARB approved and cannot be shipped to California.
