Manley Chevrolet LS Piston Set - 4.010in Bore 1.304in CH, -4.00 CC

Built from domestic 2618 alloy forgings, these Manley pistons are a solid choice for anyone looking to build a high-performance Chevrolet LS engine. The 4.010-inch bore size and -4.00cc dish volume are common specifications for many LS engine builds, offering a good balance for various applications. Manley's commitment to quality is evident in their choice of materials and manufacturing processes, aiming for both power and longevity.

You'll find that Manley uses proven cam and barrel skirt profiles on these pistons. This design helps manage piston rock within the cylinder, reducing wear on your cylinder walls while still allowing the piston to generate substantial power. They also pay close attention to the ring lands and grooves, holding them to strict standards to ensure a better seal from your piston rings, which directly translates to more power. The included tool steel wrist pins are well-built for durability, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the piston skirt, a detail that matters for optimal ring seal and engine health.

When you're putting together a serious engine, details like these make a difference. These pistons are a popular choice among professional engine builders and tuners who demand reliability and performance from their components. Keep in mind that these 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 and connecting rods that are compatible with these specifications.
