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.
