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 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 Aluminum Roller Rocker Arms
COMP Cams aluminum roller rocker arms are made from a high-quality alloy, anodized for durability and good looks. They have needle-bearing trunnions to allow for high valve spring loads (over 350 lbs.) and a tensile strength of 80,000 psi. While these rockers are more expensive than COMP Cams High Energy or Magnum rockers, they're a great choice for any race application.

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 Magnetic Deck Checkers
COMP Cams machined aluminum deck checkers incorporate magnets to hold itself firmly to the block for simple and accurate measurements. Mount a dial indicator (not included) in the center for deck height, or mount one indicator in each end to check piston rock.To calculate true compression ratio it's necessary to measure the distance between the deck surface of the block and the piston deck. Choose COMP Cams magnetic deck checkers to do the job.
