Utilizing years of valvetrain design experience, the latest FEA stress analysis technology, and an exhaustive testing regiment (dyno and Spintron), COMP Cams engineering team left no detail to chance. Everything from casting techniques to valve spring clearance was scrutinized to ensure that Ultra Pro Magnum rocker arms not only lived up to the lofty standards of their predecessor, but also took stud mount rocker performance, stability, and value to a whole new level. The most noticeable advancement centers around their nearly unbreakable investment cast 8650 chromoly 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. The new black oxide exterior finish offers a distinctive appearance, along with long-term corrosion resistance. The COMP Cams Ultra Pro Magnum rocker arms feature an oversized trunnion and precision-sorted needle bearings designed for use with high-load valve springs. 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.

COMP Cams Pro Magnum shaft mount roller rocker arms combine the strength of 8650 chromoly steel and the weight savings of aluminum rockers. COMP Cams took advantage of computer design to simulate the stresses that affect rockers under various operating loads. This allowed the engineers to lessen the rockers' mass at non-critical areas and strengthen the areas that take the most punishment. The results are rocker arms that are strong where they need to be and actually weigh 5 percent less at the valve than comparable aluminum rockers.

Dart stud girdles can help to improve the performance and reliability of engines equipped with stud-mounted rocker arms. Extra-long adjusting nuts are tightly clamped between rigid aluminum bars that prevent stud deflection under high loads. The valve motion more closely follows cam profile, producing more power and reducing breakage. Unlike universal girdles, these valvetrain stabilizers are designed to fit the specific valve locations, valve angles, and valve lengths in Dart cylinder heads. These kits include hardened poly-lock adjusting nuts.
