Manley Chevrolet 5.3L 3.785in Bore 6.125in. Rod Length 4.000in Stroke -7cc Dome Piston Set of 8

Built from domestic 2618 alloy forgings, these Manley pistons are designed for serious performance builds in Chevrolet 5.3L engines. They feature a 3.785-inch bore, a 4.000-inch stroke, and a -7cc dome, making them a solid choice for anyone looking to push their engine's capabilities. The cam and barrel skirt profiles are carefully shaped to generate substantial power while also being gentle on your cylinder walls, which helps with longevity and consistent performance.

Manley pays close attention to the details that matter for engine building. The ring lands and grooves are machined to exacting standards, which is crucial for achieving a better ring seal and ultimately, more power. Each set includes tool steel wrist pins, and for select applications like this one, Manley offers upgrades to even more durable alloys. Their unique fixturing process allows them to machine the skirt and ring grooves in a single operation, ensuring the ring groove stays perfectly square to the skirt, a detail that professional engine builders rely on for precision and reliability.

This set is intended for performance engine builds and is not CARB approved, meaning it cannot be shipped to California. If you're rebuilding your top end for increased power and durability, these Manley pistons are a well-built option that brings professional-level engineering to your project.
