Manley Chevrolet Small Block Piston Set - 4.035in Bore 1.125in CH, -2.50 CC

Manley Performance is well-known for building robust engine components that stand up to serious use. This piston set, part number 590235-8, is designed for Chevrolet Small Block engines and is built with the kind of strength and precision professional engine builders trust. If you're putting together a high-performance engine, these pistons are a solid foundation.

These pistons are forged from domestic 2618 alloy, which is chosen for its exceptional strength and ability to handle the stresses of performance engines. They feature proven cam and barrel skirt profiles, designed to generate power efficiently while also being considerate of your cylinder walls during operation. The ring lands and grooves are machined to very strict standards, which is crucial for getting a good seal from your piston rings, ultimately leading to more power and better engine efficiency. Manley uses a unique fixturing process that allows them to machine the skirt and ring grooves in the same operation, ensuring they are perfectly square to each other for optimal ring seal.

This set includes tool steel wrist pins for added durability. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct rings and connecting rods to match the piston specifications.
