Manley Chevrolet LS Piston Set - 4.135in Bore 1.065in CH, -11.00 CC

Manley Performance is well-known for building strong, reliable engine components for high-performance applications. This set of pistons is designed for Chevrolet LS engines and is built with the same attention to detail that professional engine builders trust. They feature a 4.135-inch bore and a -11.00cc dish, making them a solid choice for many LS engine builds where specific compression ratios are targeted.

These pistons are forged from domestic 2618 alloy, a material chosen for its superior strength and performance under demanding conditions. The cam and barrel skirt profiles are carefully shaped to help generate power while also being gentle on your cylinder walls, which can extend the life of your engine components. Manley also pays close attention to the ring lands and grooves, holding them to strict standards to ensure a better seal with your piston rings, leading to more efficient combustion and improved power output. The included wrist pins are made from Chrome Moly, offering good durability for most performance builds.

For those looking to build a robust LS engine, these Manley pistons are a well-built option. They are manufactured using unique fixturing that allows for skirt turning and ring groove machining in a single operation, which helps ensure the ring grooves are perfectly square to the skirt. This level of precision is important for achieving optimal ring seal and overall engine performance. Please note that these pistons are not CARB approved and cannot be shipped to California.
