Manley Chevrolet LS Piston Set - 4.005in Bore 1.304in CH, -4.00 CC

Manley Performance is well-known for building robust engine components that professional builders trust. This Chevrolet LS piston set is a prime example, designed for serious engine builds where strength and reliability are paramount. These pistons feature a 4.005-inch bore, a 1.304-inch compression height, and a -4.00cc valve relief, making them a solid choice for many LS engine configurations.

Constructed from domestic 2618 alloy forgings, these pistons offer superior strength and performance compared to cast or hypereutectic alternatives. They incorporate proven cam and barrel skirt profiles, which help generate substantial power while minimizing wear on your cylinder walls. The ring lands and grooves are machined to exacting standards, ensuring an enhanced ring seal for more efficient combustion and increased power output. For added durability, these pistons come standard with premium chrome moly wrist pins, and select SKUs like this one also feature moly skirt coatings.

Manley's unique fixturing process allows for skirt turning and ring groove machining in a single operation. This ensures ultimate squareness between the ring grooves and the piston skirt, contributing to better ring seal and overall engine health. This set is not CARB approved and cannot be shipped to California. It's important to note that this is a set of 8 pistons.
