Manley Chevrolet LS Piston Set - 4.070in Bore 1.065in CH, -20.00 CC

Manley Performance is well-known for building robust engine components that professional builders trust. This set of pistons is designed for Chevrolet LS engines and is crafted from high-strength 2618 alloy forgings. These pistons feature a 4.070-inch bore diameter, a 1.065-inch compression height, and a -20.00cc dish volume, making them a solid choice for serious engine builds.

The construction uses domestic 2618 alloy forgings, which are chosen for their superior strength and ability to handle demanding performance applications. Manley also incorporates proven cam and barrel skirt profiles, designed to generate significant power while minimizing wear on your cylinder walls. The ring lands and grooves are machined to exacting standards, which is crucial for achieving a better ring seal and unlocking more power from your engine. For added durability, these pistons come with tool steel wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt in a single operation.

This piston set is intended for custom engine builds where precise control over compression ratio and performance is key. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed for off-road use or competition engines where maximum performance and durability are required.
