Manley Chevrolet LS Piston Set - 4.135in Bore 1.115in CH, -29.00 CC

When you're building a serious LS engine, you need pistons that can handle the stress and deliver consistent power. This set from Manley Performance gives you exactly that. You get eight forged pistons, each with a 4.135-inch bore, a 1.115-inch compression height, and a -29.00 CC dish. These are designed for 8-cylinder LS engines and are built to meet the demands of professional engine builders.

Manley uses domestic 2618 alloy forgings, which are known for their strength and ability to perform under high loads. The pistons feature proven cam and barrel skirt profiles that help generate power while also being gentle on your cylinder walls, reducing wear over time. They also pay close attention to the ring lands and grooves, machining them to exacting standards to ensure a better ring seal, which translates directly to more power. For added durability, these pistons come standard with chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt for optimal performance.

This set is a solid choice for anyone looking to build a robust LS engine. 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.
