Manley Chevrolet LT1 Piston Set - 4.135in Bore 1.115in CH, -10.00 CC

This set includes eight forged pistons from Manley Performance, designed for Chevrolet LT1 engines. Each piston features a 4.135-inch bore diameter, a 1.115-inch compression height, and a -10.00cc dish volume, making them suitable for builds requiring a specific compression ratio. These pistons are crafted from domestic 2618 alloy forgings, a material known for its exceptional strength and performance capabilities, which is why professional engine builders often choose them.

Manley uses proven cam and barrel skirt profiles on these pistons. This design helps generate substantial power while also being gentle on your cylinder walls, contributing to overall engine longevity. The ring lands and grooves are machined to exacting standards, which is crucial for achieving an enhanced ring seal and unlocking more power from your engine. Each set comes standard with premium chrome moly wrist pins, and Manley's unique fixturing process allows for skirt turning and ring groove machining in a single operation. This ensures ultimate squareness between the ring groove and the skirt, a detail that matters for consistent performance.

These pistons are not CARB approved and cannot be shipped to California. If you're rebuilding your LT1 engine and need a strong, well-made set of pistons that professional tuners trust, this Manley set is a solid option.
