CP Pistons M8 120 11.0:1 (MTO Non-Cancel)

With a dome volume of -1.2 cubic inches, these CP Pistons are specifically designed for M8 engines, featuring a 4.180-inch bore size and a 4.375-inch stroke. This combination results in an 11:1 compression ratio, which is a notable increase over stock and can lead to improved power output when paired with appropriate tuning. The pistons are built to handle the demands of these larger displacement engines, offering a solid option for those looking to rebuild or upgrade their M8 powerplant.

These pistons are made for a 120 cubic inch displacement, with a dome height of 1.143 inches. They are a direct replacement for many Harley-Davidson models, including the Road King, Street Glide, and Fat Boy, among others. CP Pistons are well-known for their robust construction, making them a popular choice for riders seeking more performance from their Milwaukee-Eight engines. This set is a made-to-order item and cannot be canceled once placed.
