Manley Chevrolet LS Piston Set - 4.065in Bore 1.115in CH, -18.00 CC

When you're building a high-performance Chevrolet LS engine, the pistons are a critical component. This set from Manley Performance includes eight forged pistons, each designed to handle the demands of serious engine builds. You'll get the pistons themselves, along with tool steel wrist pins and moly skirt coatings on these specific part numbers, ready to be installed in your LS engine.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to perform under pressure. The pistons feature proven cam and barrel skirt profiles, which help generate power while also being designed to be easy on your cylinder walls. They also pay 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. Manley's unique fixturing process allows them to machine the skirt and ring grooves in one operation, ensuring they are perfectly square to each other for optimal performance.

These pistons are intended for performance applications and are not CARB approved, meaning they cannot be shipped to California. If you're looking to build a powerful LS engine, this set offers a well-built foundation with components trusted by many professional engine builders and tuners.
