What is the purpose of the -18.00 CC dish on these pistons?

The -18.00 CC dish is a specific volume designed into the piston crown. This feature is crucial for determining and setting the final compression ratio of your engine build, especially when working with different cylinder head volumes or gasket thicknesses.

What makes the 2618 alloy forgings beneficial for performance engines?

The 2618 alloy is chosen for its excellent strength and durability under high stress and temperature conditions common in performance engines. This material helps the pistons withstand the demands of increased cylinder pressures and heat.

Are these pistons suitable for all LS engine builds?

These pistons are specifically designed for LS engines with a 4.185-inch bore and feature a -18.00 CC dish. While they are built for performance, it's essential to ensure they match your specific engine's requirements, including compression ratio goals and cylinder head volume.

About this part

Product Details

This set includes eight forged pistons, each designed for Chevrolet LS engines with a 4.185-inch bore. You'll also get the necessary tool steel wrist pins and moly skirt coatings, as specified for this particular part number. These pistons feature a -18.00 CC dish, which is important for setting your compression ratio when rebuilding or modifying your engine.

Manley uses domestic 2618 alloy forgings, a material known for its strength, which is crucial for high-performance applications. The pistons have proven cam and barrel skirt profiles that help generate power while also being designed to be gentle on your cylinder walls. The ring lands and grooves are machined to exacting standards, which helps ensure a better seal from your piston rings, leading to more power. Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation, ensuring the ring grooves are perfectly square to the skirt. This attention to detail is why many professional engine builders and tuners trust Manley pistons for their builds.

When you're building a performance LS engine, getting the right pistons is a critical step. These pistons are a solid option for those looking to push their engine's performance and durability. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
