COMP Cams Ultra Pro Magnum Rocker Arms
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 Ultra Pro Magnum XD Roller Rocker Arms
Built to outlast and outperform in accuracy and strength, Ultra Pro Magnum XD roller rocker arms are engineered from durable 8650 steel and include a machined billet pushrod seat insert for a wide range of super accurate ratios. A unique and wide ratio range to fit almost any popular application from 1.5 to 1.8 in 0.5 in. increments for Chevy and 1.6 to 1.73 for various Ford applications is available. These Ultra Pro Magnum XD rockers are fully rebuildable and boast precision-sorted needle bearings and hardened roller tips. And, they work with most diameter springs and retainers. The XD design utilizes advanced FEA and CAD design and development to improve strength, stiffness and MOI (moment of inertia) optimization for drag and circle track applications.

COMP Cams Pro Magnum Shaft Mount Roller Rocker Arms
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.

COMP Cams Pro Magnum Hydraulic Roller Lifters
COMP Cams Pro Magnum hydraulic roller lifters are specifically designed to perform at higher engine speeds. When engines are equipped with a hydraulic roller camshaft, high rpm is limited by the improper positioning of the internal piston, as the lifter inevitably "pumps up." This improper location results in broken valves and, therefore, leads to lost power or sometimes even engine failure. These lifters offer a distinct advantage over standard high performance hydraulic lifters, especially in race applications where a hydraulic lifter must be used.

COMP Cams Shaft Mount Aluminum Rocker Arms
COMP Cams shaft mount aluminum rocker arms are one of the most cost-effective ways to increase horsepower. These shaft rockers were designed using the latest in computer software and engineering. They center the roller tip over the valve tip at the correct time so that the roller tip is never more than 0.020 in. off-center of the valve tip. At the greatest load point, the roller tip contact is on the center of the valve. At valve closing, the roller tip contact is slightly behind the valve centerline. When the valve is at full open, the tip contact is slightly behind the centerline of the valve. The results are more horsepower and better performance.
