New bodies and axles made of upgraded materials
Additional oiling provisions for the bearings
Heavy-duty retainers
Durable captive bearing design
Pro LS upgraded rocker arms feature high-quality rockers that have a pedestal mount, roller fulcrum style, and are made of high-grade cast steel construction to ensure long-lasting durability and performance. This design replaces the factory bearing and powdered metal trunnion and utilizes a captive bearing design and a cast steel trunnion. These rocker arms are a perfect upgrade for higher rate springs and performance camshafts. Deepmotor Pro LS upgraded rocker arms come preassembled with heavy-duty trunnion kits, which saves you time and the additional cost of an installation tool.
