Rocker Arms

COMP Cams Magnum Roller Rockers are the ultimate street rocker. That’s because they were designed with the serious performance enthusiast in mind. They will help your engine make more power and last longer.

Magnum Roller Rocker Arms are:

STRONG: Magnum Roller Rocker Arms are made from 8620 chromemoly steel. This makes them stronger than die cast aluminum or stamped steel rockers. This superior material, along with the Magnum’s super stiff design, assures maximum lift because this rocker arm will not flex.
ACCURATE: You can’t get maximum horsepower from your engine if your rocker ratio is off. Other rockers have been checked and found rockers that were as much as .040'' short on lift. The Magnum Rockers are super accurate. They check dead on every time.
POWERFUL: The Magnum Roller Rockers can make between 15 and 30 horsepower over other rockers! Why? The secret is that not only does the roller tip reduce friction, the Magnum Rockers incredibly stiff design and super accurate ratios yield more effective valve lift.
DURABLE: The roller tip design reduces friction by not scrubbing the valve end or pushing the valve stem hard against the valve guide. This in conjunction with super strong design of the rocker makes for a simple, bulletproof, and cost effective combination.

The Strongest, Lightest, Most Ratio-Accurate, and Reliable Rockers for serious street or all-out race for maximum RPM and spring pressure. The needle bearing fulcrum (on stud mount applications) and roller tip design reduces friction, lowers oil temperature and increases rpm potential. This is the only aluminum rocker available for GM self-aligning engine applications, and were chosen by GM for use on the factory built LT-4. Also available to be used with oversized rocker studs. Approved for use in California via E.O. #D-255-1. Steel heat treated adjusting nuts are included.

Before CompCams introduced our revolutionary Pro Magnum Rocker Arms there were only two alternatives in competition rocker arms: Stainless Steel for strength and reliability or Aluminum for light weight and low cost. With the Pro Magnum Rockers you get the best of both worlds.

Pro Magnum Rockers are made of 8650 chromemoly steel. This material is some three times stronger than 7075-T6 aluminum which is used for most aluminum rocker arms.

Our engineers used advanced computer technology (including Finite Element Analysis) to refine the Pro Magnum Rocker. We added strength where it was needed and reduced mass in low stress areas. The result: Pro Magnum Rocker Arms have less weight (5%) at the valve than most aluminum rockers. This means more RPM and valve train stability.

The unique design of the Pro Magnum Rocker enables us to use a larger trunion with more needle bearings. This spreads the load more evenly and the rocker will last longer.

Other features include an integral pushrod seat that insures accuracy and saves weight, a unique rocker design also provides plenty of clearance for most high performance valve springs.

Ideally suited for serious street, bracket racing, super classes, and circle track racing. You won 't find a better street rocker for the price.

Lifetime Guarantee! Pro Magnum Rocker Arms are so strong that CompCams guarantee the rocker bodies for the life against breakage!
