Manley Chevrolet LS Piston Set - 4.070in Bore 1.115in CH, -4.00 CC

Manley Performance is well-known for building strong engine components, and their LS piston sets are a popular choice for serious engine builds. This particular set is designed for Chevrolet LS engines and features a 4.070-inch bore. If you're rebuilding the top end of your LS engine, these pistons are built to handle the demands of high-performance applications.

These pistons start with domestic 2618 alloy forgings, which are chosen for their strength and ability to perform under pressure. They feature proven cam and barrel skirt profiles, designed to generate power while also being considerate of your cylinder walls. The ring lands and grooves are machined to exacting standards, which helps ensure a better seal for the piston rings, leading to more efficient combustion and increased power output. For added durability, they come standard with chrome moly wrist pins. Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation, ensuring the ring grooves are perfectly square to the skirt for optimal performance.

When building a performance LS engine, the details matter. These pistons are a solid option for those looking for well-built components that can stand up to rigorous use. Keep in mind 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.
