Manley Chevy LS Series 4.070in Bore 1.304in CD -18cc Dish Platinum Series Pistons - E/D

Manley Performance is well-known for making strong engine components that professional builders trust. If you're putting together a high-performance Chevy LS engine, these Platinum Series pistons are a solid choice. They're built with domestic 2618 alloy forgings, which means they can handle the stress and heat of a serious build. The -18cc dish design is specific for certain compression ratio targets, and the 4.070-inch bore size is common for many LS engine builds.

What sets these pistons apart is the attention to detail in their construction. They feature proven cam and barrel skirt profiles that help them make good power while being easier on your cylinder walls. Manley also machines the ring lands and grooves to very strict standards, which is crucial for getting a good seal from your piston rings and maximizing power output. The tool steel wrist pins included add to the overall durability, and for some applications, Manley offers upgraded wrist pin options if you need even more toughness.

These pistons are designed for serious engine builds, and Manley's unique manufacturing process ensures the ring grooves are perfectly square to the piston skirts. This level of precision is what helps professional engine builders achieve reliable performance and longevity. Keep in mind these are not CARB approved and cannot be shipped to California.
