Manley Small Block Chevy LS Series 4.065in Bore - 1.304in CD -4cc Dish Left Side Single Piston

This is a Manley Performance LS Series forged piston, designed for Small Block Chevy engines. It features a 4.065 inch bore, a 1.304 inch compression distance, and a -4cc dish, intended for the left side of a single-piston setup. Manley uses domestic 2618 alloy forgings, which are known for their strength and performance, making these pistons a solid choice for engine builds where durability and power are key.

The design includes proven cam and barrel skirt profiles that help generate power while also being gentle on cylinder walls. Manley also pays close attention to the ring lands and grooves, holding them to strict standards to ensure a better ring seal and improved power output. Their unique fixturing process allows for skirt turning and ring groove machining in the same operation, which helps ensure the ring grooves are perfectly square to the skirt.

These pistons come standard with Chrome Moly wrist pins, and for select applications, upgrades to 9310 and Turbo Tuff/DLC alloys are available for even greater durability. Please note that this part is not CARB approved and cannot be shipped to California.
