Manley Chevrolet LS Piston Set - 4.075in Bore 1.065in CH, -20.00 CC

Built from domestic 2618 alloy forgings, these Manley pistons are a solid choice for anyone looking to build a serious Chevrolet LS engine. The 4.075-inch bore size and -20.00cc dish volume are key specifications for achieving specific compression ratios, especially when paired with the 1.065-inch compression height. This particular setup is designed to work with a variety of LS engine configurations, offering a strong foundation for performance builds.

Manley's attention to detail is evident in the cam and barrel skirt profiles, which are shaped to generate power efficiently while minimizing wear on your cylinder walls. They also hold exacting standards for the ring lands and grooves, which is crucial for a good seal and maximizing the power your engine makes. For added durability, these pistons come standard with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, a detail that matters for consistent performance and longevity.

When you're building an engine where reliability and performance are paramount, choosing well-built components like these Manley pistons is essential. They are a popular choice among professional engine builders and tuners who demand the best for their projects. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
