Manley Chevrolet LS Piston Set - 4.070in Bore 1.115in CH, -10.00 CC

When you're building a high-performance Chevrolet LS engine, you need components that can handle the stress. This set of Manley pistons is built for just that. You get eight forged pistons, each with a 4.070-inch bore diameter and a -10.00cc dish volume, designed to work with your specific LS engine configuration. The 1.115-inch compression height is also a key measurement for achieving your desired compression ratio.

Manley uses domestic 2618 alloy forgings, which are known for their strength and ability to perform under demanding conditions. These pistons feature proven cam and barrel skirt profiles, which help them generate power efficiently while also being easier on your cylinder walls. The ring lands and grooves are machined to very precise standards, which is crucial for getting a good seal from your piston rings, leading to more power and better engine efficiency. Each set also includes tool steel wrist pins for added durability, and some select part numbers offer upgrades to even stronger alloys.

Manley's manufacturing process is notable. They use unique fixturing that allows them to machine the piston skirt and the ring grooves in the same operation. This ensures that the ring grooves are perfectly square to the piston skirt, which is important for optimal ring seal and overall engine performance. These pistons are a solid choice for serious engine builds where reliability and power are top priorities.
