Manley Chevrolet LS Piston Set - 4.080in Bore 1.065in CH, -20.00 CC

This set includes eight forged pistons from Manley Performance, designed for Chevrolet LS engines. Each piston features a 4.080-inch bore, a 1.065-inch compression height, and a -20.00cc dish volume. These pistons are built using Manley's signature 2618 alloy forgings, a material known for its exceptional strength and durability, making them a solid choice for serious engine builds. They come standard with premium chrome moly wrist pins, and Manley adheres to strict standards for ring lands and grooves to ensure a better ring seal and improved power output.

Manley's design includes proven cam and barrel skirt profiles, which help generate substantial power while minimizing wear on cylinder walls. A unique fixturing process allows for skirt turning and ring groove machining in a single operation, ensuring the ring grooves are perfectly square to the skirt. This attention to detail is why professional engine builders and tuners often rely on Manley pistons for high-performance applications where reliability and power are critical.

This piston set is intended for engine rebuilding and performance tuning. Please note that these pistons are not CARB approved and cannot be shipped to California. It is recommended to consult manufacturer installation instructions for proper fitment and assembly procedures.
