Rocker Arms & Bridges
Valve geometry is super critical for the correct operation of the valves on a cylinder head. Rocker arms and bridges are subject to extreme wear, re-using these components is a sure-fire way to end up with a variety of valve sealing and oil consumption problems. When replacing cylinder heads, it is important to use new rocker arms and valve bridges to provide the correct valve geometry. Our valvetrain components have been selected for their quality and performance, as well as ease of installation and fitment.
