Manley Chevy LT1 Direct Injected Series 4.00in Stroke 4.130in Bore -10 cc Dish Extreme Duty Pistons

This set includes eight Manley Chevy LT1 Direct Injected Series Extreme Duty pistons, each featuring a -10 cc dish. These pistons are designed for a 4.00-inch stroke and a 4.130-inch bore, making them a robust choice for rebuilding or upgrading your LT1 engine.

Manley uses domestic 2618 alloy forgings for these pistons, a material known for its strength and ability to handle demanding conditions. They come standard with premium chrome moly wrist pins, and for even greater durability, upgrades to 9310 and Turbo Tuff/DLC alloys are available on select part numbers. The ring lands and grooves are machined to exacting standards, which helps ensure a better seal from your piston rings, leading to more power. The pistons also feature proven cam and barrel skirt profiles that are designed to generate power efficiently while minimizing wear on your cylinder walls. Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation, ensuring the ring grooves are perfectly square to the 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 high-stress applications. Please note that these pistons are not CARB approved and cannot be shipped to California.
