Manley Chevrolet LT1 Piston Set - 4.135in Bore 1.115in CH, -20.00 CC

Forged from domestic 2618 alloy, these Manley pistons are built for serious performance builds. They feature a 4.135-inch bore size and a -20.00cc dish volume, making them suitable for specific compression ratio targets in Chevrolet LT1 engines. The cam and barrel skirt profiles are carefully designed to generate substantial power while also being gentle on your cylinder walls, reducing wear over time. Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation, ensuring the ring grooves are perfectly square to the skirt for improved ring seal and more power.

You'll find exacting standards applied to the ring lands and grooves, which is crucial for getting a solid seal from your piston rings. This attention to detail translates directly into better engine performance and durability. Each set includes tool steel wrist pins, known for their strength and reliability under high stress. If you're building a high-performance LT1 engine and need pistons that can handle the demands of professional engine builders and tuners, these Manley pistons are a solid choice.

This piston set is not CARB approved and cannot be shipped to California. Please ensure you check all manufacturer specifications and compatibility requirements for your specific engine build before installation.
