Manley Chevrolet Big Block Piston Set - 4.500in Bore 1.120in CH, 43.00 CC

If you're rebuilding a Chevrolet big block engine for serious performance, a strong set of pistons is where it all starts. These Manley Performance pistons are built for the demands of high-horsepower applications, using a domestic 2618 alloy forging that's known for its strength and durability under extreme conditions. They're designed to handle the pressures and heat that come with pushing your engine to its limits.

Manley puts a lot of thought into the details that make a difference. These pistons feature proven cam and barrel skirt profiles, which help them run smoothly against the cylinder walls while still generating substantial power. The ring lands and grooves are machined to very strict standards, which is crucial for getting a good seal from your piston rings – that means more power and better efficiency. They also come with chrome moly wrist pins, a solid choice for durability, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, which is key for proper ring function.

When you're building an engine where every component needs to perform reliably, choosing well-built parts like these Manley pistons is a smart move. They are a popular choice among professional engine builders for a reason. Keep in mind that these are not CARB approved and cannot be shipped to California.
