Manley Chevy LT1 4.075in Bore -2cc Dome 11.7 CR Piston Set Of 8

This set includes eight forged pistons for your Chevy LT1 engine, each featuring a -2cc dome and designed for a 4.075-inch bore. These pistons are built using Manley's signature 2618 alloy forgings, a domestic material known for its superior strength and performance capabilities, making them a solid choice for serious engine builds. They come standard with premium chrome moly wrist pins, and Manley adheres to strict standards for piston ring lands and grooves, which helps ensure enhanced ring seal and ultimately, more power. The cam and barrel skirt profiles are engineered to generate substantial power while also being gentle on your cylinder walls, 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 grooves and the skirt, a detail that professional engine builders and tuners rely on for durability and performance.

When rebuilding or upgrading your LT1 engine, choosing the right pistons is critical. These Manley pistons are a popular choice among those looking to push their engine's performance further. The 2618 alloy offers a strong foundation, and the precise machining of the ring lands and grooves contributes to a better seal. The included chrome moly wrist pins are well-built and ready for the demands of a performance engine. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal results, always refer to the manufacturer's installation instructions and recommended assembly procedures.
