Product Overview
The Scorpion 7/16″ roller rocker arm set is built specifically for Big Block Chevrolet engines. Each arm features a full roller that glides over the pushrod, dramatically reducing friction compared to traditional flat‑tappet designs. Constructed from lightweight yet strong aluminum and finished with a durable blue anodized coating, the arms resist wear and corrosion even under high‑temperature conditions. The set includes 16 precisely machined arms, each matching the 7/16″ stud size for a perfect fit.
