Manley Chevrolet LS Piston Set - 4.135in Bore 1.115in CH, -18.00 CC

Manley Performance is well-known for building robust engine components that professional builders trust. This set of pistons is designed for Chevrolet LS engines and is a solid choice when you're looking to build a high-performance powerplant. They feature a 4.135-inch bore and a -18.00 CC dish, which is important for setting your compression ratio.

These pistons are forged from 2618 alloy, a material chosen for its exceptional strength and ability to handle demanding conditions. They come equipped with Chrome Moly wrist pins, and this particular set also includes a moly skirt coating. This coating helps reduce friction and wear on the cylinder walls, contributing to both improved power output and longer engine life. Manley pays close attention to the details, ensuring the ring lands and grooves are machined to exact standards for a better seal. The cam and barrel skirt profiles are also carefully designed to generate power efficiently while being easy on the cylinder walls.

Manley's manufacturing process uses unique fixturing that allows them to machine the skirt and ring grooves in one operation. This ensures the ring grooves are perfectly square to the skirt, which is critical for proper ring seal and overall engine performance. This set is a great option for anyone rebuilding or upgrading their LS engine and looking for reliable, well-built internal components.
