Manley Chevrolet LS Piston Set - 4.080in Bore 1.304in CH, -18.00 CC

This set includes eight forged pistons for your Chevrolet LS engine, featuring a 4.080-inch bore and a -18.00 cubic centimeter dish. These pistons are built using Manley's signature Platinum Series construction, which starts with domestic 2618 alloy forgings known for their exceptional strength and performance under demanding conditions. They also come standard with premium chrome moly wrist pins, designed for added durability.

Manley pays close attention to the details that make a difference in engine power and longevity. The ring lands and grooves are machined to exacting standards, which helps ensure a better seal for your piston rings, leading to more power. The pistons feature proven cam and barrel skirt profiles that are shaped to generate significant power while also being gentle on your cylinder walls. This design, combined with Manley's unique fixturing process that allows skirt turning and ring groove machining in a single operation, ensures ultimate squareness between the ring grooves and the piston skirt.

These pistons are a solid choice for anyone building or rebuilding a high-performance LS engine. Keep in mind that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
