What is the compression ratio impact of the -18.00 CC dish?

The -18.00 CC dish volume is a key factor in determining your engine's final compression ratio. It works in conjunction with your cylinder head volume, head gasket thickness, and deck height. This dish is commonly used in naturally aspirated or forced induction builds to achieve specific compression targets.

What is the advantage of 2618 alloy forgings?

2618 alloy is chosen for its exceptional strength and ductility, making it ideal for high-performance pistons. It can withstand higher cylinder pressures and temperatures compared to cast or hypereutectic aluminum, offering superior durability in demanding applications.

Are rings and connecting rods included with this piston set?

This listing is for the Manley Performance piston set only. Rings and connecting rods are sold separately. You will need to select compatible components to complete your engine build.

About this part

Product Details

When you're rebuilding the heart of your Chevrolet LS engine, choosing the right pistons is critical for performance and longevity. This set from Manley Performance is built for demanding builds where strength and reliability are paramount. They feature a 4.070-inch bore size and a -18.00 CC dish, which is a common configuration for naturally aspirated or forced induction setups that require a specific compression ratio.

Manley uses domestic 2618 alloy forgings for these pistons, a material known for its exceptional strength and ability to handle high cylinder pressures and temperatures. The pistons are also equipped with proven cam and barrel skirt profiles, designed to reduce friction and wear on your cylinder walls while still generating substantial power. You'll also find exacting standards in the ring lands and grooves, which are crucial for achieving a solid ring seal and maximizing the power your engine can produce. To further enhance durability, these pistons include premium 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 popular choice among professional engine builders and tuners who trust Manley for their high-performance engine components. While these pistons are not CARB approved and cannot be shipped to California, they represent a solid option for serious engine builds where every component needs to perform reliably under stress. Ensure you have the correct supporting components, such as rings and connecting rods, to match the specifications of these pistons for a complete and effective engine build.
