Here at Manton, we offer a roller rocker arm assembly for the 2001-2023 Duramax engine. The assembly features Manton’s Top Fuel proven pin and roller combination on the valve side, which reduces side thrust on the valve by removing the scrubber from the rocker arm. The assembly keeps the factory rocker arm ratios and utilizes the existing camshaft. Our Duramax rocker arm bodies, and component pieces are made of proprietary tool steels, which help improve overall performance and increase service life by minimizing deflection.
