In the world of high-performance engine building, the lighter the weight of critical compontery such as rotating assembly or valvetrain, the more responsive the throttle feels and the faster you can spin the engine.

Comp Cams just released a new breed of rocker arms designed to increase strength and shave off weight where it counts most: the valvetrain.

Check out the press release below:

The most noticeable advancement with the COMP Cams Ultra Pro Magnum Rocker Arms centers around their nearly unbreakable investment cast 8650 chromemoly body. The arched, web-like design delivers a nearly 29% increase in strength and rigidity while reducing the moment of inertia and optimizing the dynamic balance. The resulting rocker maximizes lift and valve train control at high rpm. The increased retainer and valve spring clearances of the new design enable the use of large diameter valve springs, retainers and locks without clearance or fitment issues. As further testament to the strength of this design, COMP Cams® includes a lifetime guarantee against the breakage of the rocker arm body for any reason.

 Even the fit and finish of this innovative new rocker from COMP Cams provides its advantages. The new black oxide exterior finish offers a distinctive appearance along with long term corrosion resistance.

The Ultra Pro Magnum Rocker Arms from COMP Cams feature an oversized trunion and precision-sorted needle bearings for use with high load valve springs. Additionally, these unique rockers also feature hardened roller tips for reduced friction and elimination of the valve stem “side loading” that causes premature valve guide wear. And like the previous generation Pro Magnums, these new rockers feature a fully rebuildable design that means they very well may be the last rocker arms you ever have to purchase.

 The new COMP Cams Ultra Pro Magnum Rocker Arms are available for most popular Chevy and Ford performance engine applications that utilize stud mount rockers arms. For more info call Comp Cams at 1-800-999-0853
