Manley Chevrolet LS Piston Set - 4.065in Bore 1.304in CH, -4.00 CC

When you're building a high-performance Chevrolet LS engine, starting with the right pistons is crucial. This set from Manley Performance includes eight forged pistons, each designed to handle the demands of serious engine builds. You'll receive the pistons themselves, along with the necessary tool steel wrist pins and wire locks to get them installed. These aren't just any pistons; they're crafted from domestic 2618 alloy, a material known for its exceptional strength and ability to perform under high stress, making them a popular choice among professional engine builders.

Manley has put a lot of thought into the design of these pistons. They feature proven cam and barrel skirt profiles, which help generate significant power while also being designed to be gentle on your cylinder walls. This means less wear over time and a more consistent performance. The ring lands and grooves are machined to exacting standards, which is key for achieving a solid ring seal. A good ring seal is essential for maximizing compression and getting every bit of power out of your engine. Manley also uses a unique fixturing process that allows them to machine the skirt and ring grooves in a single operation, ensuring they are perfectly square to each other for optimal performance.

These pistons are built for durability, featuring premium chrome moly wrist pins as standard. For those looking for even more robustness, Manley offers upgrades to 9310 and Turbo Tuff/DLC alloys on select part numbers. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're aiming for serious power and reliability in your LS engine build, this set of Manley pistons is a solid option.
