The most noticeable advancement centers around their nearly unbreakable investment cast 8650 chromemoly body. The arched, web-like design delivers a nearly 29 percent increase in strength and rigidity, while reducing the moment of inertia and optimizing the dynamic balance. The resulting rockers maximize lift and valvetrain 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. Ultra Pro Magnum rocker arms feature an oversized trunnion and precision-sorted needle bearings designed for use with high-load valve springs. Additionally, these rockers feature hardened roller tips for reduced friction and elimination of the valve stem “side loading” that causes premature valve guide wear. Fully rebuildable.
