Manley Chevrolet LS Piston Set - 4.075in Bore 1.065in CH, -31.00 CC

This set includes eight forged pistons, each designed for Chevrolet LS engines. These pistons are built with a 4.075-inch bore size, a 1.065-inch compression height, and a -31.00cc dish volume, making them suitable for performance builds where precise compression ratios are key. They come standard with chrome moly wrist pins for added durability.

Manley uses domestic 2618 alloy forgings, which are known for their strength and ability to handle high performance demands. The pistons feature proven cam and barrel skirt profiles that help generate power while also being designed to be gentle on cylinder walls, reducing wear. The ring lands and grooves are machined to exacting standards, which is crucial for achieving a good seal with the piston rings, ultimately leading to more power and better engine efficiency. Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation, ensuring the ring grooves are perfectly square to the skirt.

These pistons are a solid option for engine builders and tuners looking for reliable components for their performance LS engines. Please note that these pistons are not CARB approved and cannot be shipped to California.
