Description
GM LS rocker arms are critical to maximizing valve lift and duration without sacrificing reliability—these 1.7-ratio roller units directly increase flow efficiency and reduce parasitic drag compared to stock geometry. A full-roller design eliminates friction points, allowing higher RPM capability and more consistent lift across the entire valve event. If you’re building a serious LS engine for street or strip, upgrading to dedicated race rocker arms is one of the highest-ROI modifications you can make.
