Manley Chevrolet LS Piston Set - 4.130in Bore 1.115in CH, -18.00 CC

This set includes eight forged pistons, designed for Chevrolet LS engines. Each piston features a 4.130-inch bore, a 1.115-inch compression height, and a -18.00cc dish. These pistons are built using Manley's signature Platinum Series construction, which starts with domestic 2618 alloy forgings known for their strength and performance capabilities. This material choice is crucial for engines that see demanding use, providing a solid foundation for power and reliability.

Manley pays close attention to the details that make a difference in engine performance. The pistons feature proven cam and barrel skirt profiles, which help generate substantial power while also being designed to minimize wear on cylinder walls. The ring lands and grooves are machined to exacting standards, which is key for achieving a better ring seal. A good ring seal means more efficient combustion and ultimately, more power. For added durability, these pistons come standard with premium chrome moly wrist pins. Manley's unique fixturing process allows for skirt turning and ring groove machining in a single operation, ensuring the ring grooves remain perfectly square to the piston skirt for optimal performance.

These pistons are a popular choice among professional engine builders and tuners who rely on Manley for superior performance and durability in their LS builds. Please note that this part is not CARB approved and cannot be shipped to California.
