About this part

Product Details

Built with domestic 2618 alloy forgings, these Manley pistons are designed for serious performance builds. The 4.135-inch bore size and -20.00cc dish volume are specific choices for certain LS engine configurations, aiming to achieve a particular compression ratio when paired with the right cylinder heads and gasket. This set is a popular choice among professional engine builders and tuners who need reliable components for demanding applications.

Manley's signature cam and barrel skirt profiles are engineered to reduce friction and wear on your cylinder walls while still generating substantial power. They also pay close attention to the ring lands and grooves, holding them to strict standards to ensure an enhanced ring seal, which directly translates to more power. The pistons come standard with premium chrome moly wrist pins, and for even more durability, Manley offers upgrades to 9310 and Turbo Tuff/DLC alloys on select part numbers. Their 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 for optimal performance.

This piston set is a solid option for anyone rebuilding or upgrading their Chevrolet LS engine. 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.
