Comp Cams Pro Magnum Full Roller Rocker Arms

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 3 times stronger than 7075T-6 aluminum shich is used for most aluminum rocker arms. Comp's engineers used advanced computer technology (including Finite Element Analysis) to refine the Pro Magnum Rocker. 
Comp 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 Comp 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.

Rebuildable!
Unlike aluminum rockers, this heavy duty rocker can be rebuilt. Comp will disassemble and inspect it, then replace the roller tip, axle, trunion and bearings to make your rockers like new.

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