Manley Chevrolet LS Piston Set - 4.165in Bore 1.315in CH, -31.00 CC

When you're building a high-performance Chevrolet LS engine, you need pistons that can handle the stress and deliver reliable power. This set from Manley Performance includes forged pistons designed for LS engines, featuring a 4.165-inch bore and a -31.00 CC dish volume. These pistons are built with domestic 2618 alloy forgings, a material known for its exceptional strength and ability to perform under demanding conditions. They also come standard with premium chrome moly wrist pins, which add to their overall durability.

Manley has put a lot of thought into the design of these pistons. They feature proven cam and barrel skirt profiles that are engineered to generate significant power while also being considerate of your cylinder walls, helping to reduce wear. The ring lands and grooves are machined to very strict standards, which is crucial for achieving a solid ring seal and maximizing the power your engine can produce. Furthermore, Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation. This ensures the ring grooves are perfectly square to the skirt, contributing to better performance and longevity.

This piston set is a solid choice for serious engine builders looking for robust components for their LS project. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
