Manley Chevrolet LS Piston Set - 4.065in Bore 1.065in CH, -20.00 CC

Forged from domestic 2618 alloy, these Manley pistons are built for serious performance in Chevrolet LS engines. The 4.065-inch bore size and -20.00cc dish volume are key specifications for builders aiming for specific compression ratios and displacement targets. This set is designed to handle the demands of high-performance builds, offering a solid foundation for your engine project.

Manley's signature cam and barrel skirt profiles are incorporated to help generate power efficiently while minimizing wear on the cylinder walls. You'll also find exacting standards applied to the ring lands and grooves, which is crucial for achieving a strong seal and maximizing the power output from your engine. Each set includes premium Chrome Moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, a detail that matters for consistent performance and durability under load.

This piston set is a popular choice among professional engine builders and tuners who rely on Manley for their superior performance and durability. If you're rebuilding a Chevrolet LS engine and need pistons that can withstand significant stress and deliver reliable power, this set is a well-built option. Please note that these pistons are not CARB approved and cannot be shipped to California.
