What is the benefit of a roller tip rocker arm?

A roller tip reduces friction where the rocker arm contacts the valve stem. This means less power is lost to friction, allowing for more effective valve lift and potentially a longer lifespan for your valvetrain components.

What kind of spring pressure can these rockers handle?

These COMP Cams Magnum Roller Rocker Arms are recommended for applications with less than 350 lbs. of open spring pressure. Exceeding this may affect performance and durability.

Do these rocker arms come as a set?

Yes, this is a set of 8 rocker arms, which is the correct quantity for a V8 engine.

Product Details

Built from 8620 chromemoly steel, these COMP Cams Magnum Roller Rocker Arms are a well-built choice for your Ford V8 engine. They're designed to minimize flex, ensuring that you get the most effective valve lift possible from your camshaft. This is important because it directly impacts how much air and fuel get into your cylinders, which translates to more power. The roller tip on these arms is a key feature, as it significantly reduces friction compared to traditional stamped steel rockers. Less friction means less power loss and a longer lifespan for your valvetrain components.

With a 1.6 ratio and a 3/8" stud diameter, these rockers are a popular upgrade for street performance applications. They are well-suited for engines with less than 350 lbs. of open spring pressure. You can expect an improved horsepower gain over stock rocker arms. Look for the COMP Cams logo stamped on the underside to confirm you have a genuine Magnum Roller Rocker.

These rocker arms fit a wide range of Ford engines, including those found in vehicles like the Ford Bronco, Ford F-150, and Ford Mustang. Always check the full fitment list to confirm compatibility with your specific application.
