Manley Chevrolet LS Piston Set - 4.125in Bore 1.115in CH, -18.00 CC

Manley Performance is well-known for building serious engine components, and their LS piston sets are a popular choice for builders looking for reliable performance. This particular set is designed for Chevrolet LS engines and features a 4.125-inch bore with a 1.115-inch compression height and an -18.00 CC dish volume. These pistons are built to handle demanding builds, whether you're assembling a street/strip machine or a dedicated race engine.

These pistons start with domestic 2618 alloy forgings, which are chosen for their exceptional strength and ability to withstand high cylinder pressures and temperatures. Manley also incorporates proven cam and barrel skirt profiles. These profiles help manage piston movement within the cylinder, reducing wear on the cylinder walls while still allowing the piston to generate substantial power. The ring lands and grooves are machined to exacting standards, which is critical for achieving a solid ring seal. A good ring seal means better compression, more power, and less blow-by. For added durability, these pistons come standard with premium chrome moly wrist pins, and Manley's unique fixturing process allows for skirt turning and ring groove machining in a single operation, ensuring the ring grooves are perfectly square to the piston skirt.

This piston set is intended for performance engine builds and is not CARB approved, meaning it cannot be shipped to California. When building a high-performance LS engine, choosing the right pistons is fundamental to achieving your goals for power and reliability.
