What is the significance of the 2618 alloy forging?

The 2618 alloy is a strong, heat-treatable aluminum alloy commonly used in high-performance pistons. It offers excellent strength and durability, making it well-suited for demanding engine applications where high cylinder pressures are expected.

What does the -11.00 CC dish volume mean for my engine?

The -11.00cc dish volume is a measurement of the concave volume in the piston's crown. This specification is crucial for determining the final compression ratio of your engine when combined with the cylinder head volume and gasket thickness.

Are piston rings included with this set?

This listing is for the Manley Performance piston set only. Piston rings and connecting rods are typically sold separately and must be chosen to be compatible with these pistons and your specific engine build.

About this part

Product Details

Starting with domestic 2618 alloy forgings, these Manley pistons are built for serious performance in Chevrolet LS engines. The 4.185-inch bore size and -11.00cc dish volume are specific choices for certain engine builds, often aimed at naturally aspirated or forced induction applications where precise compression ratios are key. The 1.315-inch compression height is also a critical measurement that affects how the piston sits in the cylinder relative to the crankshaft and cylinder head.

Manley's signature cam and barrel skirt profiles are designed to manage piston rock, reducing noise and wear on cylinder walls while still allowing the piston to generate substantial power. They've also paid close attention to the ring lands and grooves, holding them to strict standards to ensure a better seal from your piston rings, which translates directly to more power and efficiency. The included chrome moly wrist pins are well-built for durability, and Manley's unique manufacturing process ensures that the ring grooves are perfectly square to the piston skirt, further enhancing that crucial ring seal.

This set is intended for builders who understand the importance of quality internal engine components. While these pistons are built for durability, remember that they are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct rings, connecting rods, and bearings that are compatible with these specific pistons and your intended engine configuration.
