Manley Chevrolet LT1 Piston Set - 4.080in Bore 1.115in CH, -20.00 CC

This set includes eight forged pistons from Manley Performance, designed for Chevrolet LT1 engines. Each piston features a 4.080-inch bore size and a -20.00cc dish volume, with a 1.115-inch compression height. These are built using Manley's signature Platinum Series construction, which starts with domestic 2618 alloy forgings known for their strength and performance capabilities.

Manley uses proven cam and barrel skirt profiles on these pistons, which are designed to generate significant power while also being gentle on your cylinder walls. The ring lands and grooves are machined to exacting standards, which helps ensure a better ring seal and ultimately more power from your engine. For added durability, these pistons come with tool steel wrist pins, and select part numbers offer upgrades to even stronger alloys. The unique fixturing Manley employs allows for skirt turning and ring groove machining in a single operation, ensuring the ring grooves are perfectly square to the piston skirt.

These pistons are a solid choice for anyone rebuilding or upgrading their LT1 engine, whether you're a professional builder or a serious enthusiast. They are built to withstand the demands of high-performance applications, offering a strong foundation for your engine build. Please note that these pistons are not CARB approved and cannot be shipped to California.
