Manley Chevrolet LT1 Piston Set - 4.075in Bore 1.115in CH, -20.00 CC

Built from domestic 2618 alloy forgings, these Manley pistons are a strong choice for anyone rebuilding or upgrading their Chevrolet LT1 engine. The 4.075-inch bore size and -20.00cc dish volume are specific dimensions that matter when you're aiming for a particular compression ratio and displacement. Professional engine builders often turn to Manley because they know these pistons are made to handle serious power and deliver consistent results.

Manley pays close attention to the details that make a difference in engine performance and longevity. The cam and barrel skirt profiles are designed to reduce friction and wear on the cylinder walls while still generating substantial power. They also machine the ring lands and grooves to very strict standards, which is crucial for getting a good seal from your piston rings. This attention to detail helps ensure you get the most power out of every combustion cycle and keeps your engine running smoothly.

Included with these pistons are premium chrome moly wrist pins, which are a solid component for handling the stresses within the engine. Manley's unique manufacturing process allows them to machine the skirt and ring grooves in a single operation, ensuring they are perfectly square to each other. This level of precision is what separates a good engine build from a great one. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
