Manley Chevrolet LS Piston Set - 4.125in Bore 1.115in CH, -18.00 CC

Manley Performance is well-known for building strong, reliable engine components for serious builds. This set of pistons is designed for Chevrolet LS engines and is a popular choice among professional engine builders and tuners looking for dependable performance. They feature a 4.125-inch bore and a -18.00cc dish, making them suitable for a variety of performance applications where a specific compression ratio is desired.

These pistons are forged from domestic 2618 alloy, which provides superior strength and durability compared to cast pistons. They also feature proven cam and barrel skirt profiles, which help generate power while being gentle on your cylinder walls. The ring lands and grooves are machined to exacting standards to ensure an enhanced ring seal, contributing to more power output. Manley's unique fixturing process allows for skirt turning and ring groove machining in a single operation, ensuring ultimate squareness between the ring groove and the skirt for consistent performance.

Included with this piston set are premium Chrome Moly wrist pins. For those seeking even greater durability, Manley offers upgrades to 9310 and Turbo Tuff/DLC alloys on select part numbers. These pistons are not CARB approved and cannot be shipped to California. Please refer to manufacturer installation instructions for proper setup and assembly.
