Manley Chevrolet LS Piston Set - 4.080in Bore 1.115in CH, -4.00 CC

Manley Performance is well-known for building serious engine components, and their LS piston sets are a popular choice for builders who need reliable parts for high-performance applications. This specific set is designed for Chevrolet LS engines and features a 4.080-inch bore with a -4.00cc dish volume and a 1.115-inch compression height. These pistons are built to handle the demands of powerful engines, whether you're building a race car or a serious street machine.

The heart of these pistons is their construction from domestic 2618 alloy forgings, which are chosen for their superior strength and ability to perform under high stress. They also come standard with premium chrome moly wrist pins, known for their durability. Manley pays close attention to the details, ensuring exacting standards for the ring lands and grooves. This precision helps achieve a better ring seal, which translates directly into more power. The cam and barrel skirt profiles are carefully designed to generate substantial power while also being gentle on your cylinder walls, promoting longer engine life.

Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation. This ensures ultimate squareness between the ring grooves and the skirt, a critical detail for proper ring function and sealing. These pistons are a solid option for anyone rebuilding or upgrading their LS engine and looking for well-built components that can stand up to the rigors of performance driving. Please note that these pistons are not CARB approved and cannot be shipped to California.
