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's XD-A pushrods offer a game-changing method for accurately setting lash or pre-load while using non-adjustable-style rockers. These patent-pending pushrods incorporate a top section that slides 2 in. inside a wider bottom section, with one or two shims captured in-between. Proven to 9,000-plus rpm in solid roller LS applications, the system provides a 90 percent increase in bending stiffness for enhanced valvetrain stability. It also allows for lightening of a rocker arm system by 30-plus grams on the backside by removing the adjuster and required support area for threads and seating. The use of lighter rockers with XD-A adjustable pushrods allow higher rpm to be achieved by creating a much more dynamically stable valvetrain system. COMP Cam XD-A pushrods are designed especially for engines with low-mass rocker arms and a light valvetrain with drop-in fitment in LS engines. They can be adjusted over a range of .172 in. in .004 in. increments with shims. Choose the pushrods with the adjustment range needed for your setup.
