Developed to work in concert with the Screamin’ Eagle® Milwaukee-Eight® 128CI and 131CI Stage IV kits, these pistons increase the engine’s compression and deliver impressive gains in torque and horsepower when coupled with those kits. Forged from high-strength aluminum, the pistons are precision-machined and feature coated skirts for a tight-tolerance fit and quieter operation. Complete kit includes two pistons, rings, wrist pins and clips.

FITMENT: Replacement pistons for '17-later Milwaukee-Eight models equipped with 128CI Stage IV kits.
