COMP Cams Rocker Arms FS/FW 1.6 3/8 Ultra

When you're rebuilding the top end of your Ford V8, like a 289, 302, or 351 Windsor, getting the rocker arms right is crucial for performance and reliability. These Ultra Pro Magnum roller rocker arms from COMP Cams are built to handle serious work, offering improved stability and durability over stock components. They feature a 1.6 ratio, which means the valve will open and close more with the same amount of camshaft lift, potentially improving airflow and power.

What sets these apart is their construction. They're made from investment cast 8650 chromemoly steel, giving them a strong and rigid body that resists flexing under pressure. This material, combined with an arched, web-like design, helps reduce rotational weight while maintaining solid strength. The black oxide exterior finish not only looks good but also helps prevent corrosion, adding to their longevity. Inside, you'll find oversized trunnions for better support, precision-sorted needle bearings for smooth operation, and hardened roller tips to minimize friction and wear on your valve stems. COMP Cams also optimized the clearance for retainers and valve springs, so you can use most common spring diameters and locks without issues, even up to +.050" locks.

These rocker arms are designed to work with engines using a 3/8" stud diameter and can handle up to 850 lbs of open spring pressure, making them suitable for many performance builds. COMP Cams backs these with a lifetime warranty against breakage, showing their confidence in the product's strength. They fit a wide range of Ford V8s and many other V8 applications from the 1960s through the 1990s, including popular models like the Ford Bronco, F-100, and various Ford station wagons and custom models.
