The Edelbrock Red Roller wide‑body rocker arm set (qty 16) is a 1.5:1 ratio solution for small‑block Chevy engines using 3/8" studs. Wide‑body construction increases contact area while the 7129 aluminum bodies are CNC‑machined, micro‑polished and anodized in the USA. Centerless‑ground trunnion race, roller pin and roller tip with a Torrington needle bearing fulcrum yield smooth operation. The set supports springs up to 1.65" and includes robust adjusters and locks.
