Manley Chevrolet LS Piston Set - 4.080in Bore 1.115in CH, -10.00 CC

When you're building a high-performance Chevrolet LS engine, you need pistons that can handle the stress and deliver consistent power. This set from Manley Performance includes eight forged pistons, each designed for a 4.080-inch bore with a 1.115-inch compression height and a -10.00cc dish volume. These aren't just any pistons; they're crafted from domestic 2618 alloy forgings, a material known for its exceptional strength and reliability under demanding conditions. You'll also find that each set comes with premium chrome moly wrist pins, which are crucial for connecting the piston to the connecting rod and handling the forces involved.

Manley puts a lot of thought into the details that make a difference. The cam and barrel skirt profiles are carefully shaped to help generate significant power while also being gentle on your cylinder walls, reducing wear over time. They also adhere to strict standards for the ring lands and grooves, which is essential for achieving a good seal with your piston rings. A tight seal means better compression and more power. Plus, their unique fixturing process allows them to machine the skirt and ring grooves in one operation, ensuring the ring grooves are perfectly square to the skirt, which further aids in sealing and performance.

This piston set is a solid choice for serious engine builders looking for durable components. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct piston rings, connecting rods, and bearings to match these high-performance pistons.
