Manley Chevrolet LS Piston Set - 4.135in Bore 1.065in CH, -11.00 CC

Built from domestic 2618 alloy forgings, these Manley pistons are designed for serious LS engine builds. The 4.135-inch bore size and -11.00cc dish volume are key specifications for achieving specific compression ratios, especially when paired with compatible cylinder heads and head gaskets. This set is a popular choice among professional engine builders and tuners who demand reliability and performance from their components.

Manley's signature cam and barrel skirt profiles are engineered to generate substantial power while minimizing wear on your cylinder walls. The exacting standards applied to the ring lands and grooves are crucial for ensuring a tight seal, which directly translates to more efficient combustion and improved power output. Furthermore, the unique fixturing Manley uses allows for skirt turning and ring groove machining in a single operation, ensuring the ring grooves are perfectly square to the skirt for optimal performance.

Included with this piston set are premium chrome moly wrist pins, known for their durability. For those looking for even greater longevity and strength, Manley offers upgraded wrist pin options in 9310 and Turbo Tuff/DLC alloys. This attention to detail in materials and manufacturing makes Manley pistons a solid option for high-performance engine builds where every component needs to perform under pressure.
