    Industry's top selling steel roller rocker arms have been completely redesigned for reduced weight and greater strength, yielding increased valve train stability

    The original Pro Magnum stud mount rocker arm design has been the standard of the industry for almost 20 years, but recent advancements in design capabilities and steel casting processes have paved the way for a "clean sheet" redesign. Utilizing years of valve train design experience, the latest FEA stress analysis technology and an exhaustive testing regiment (dyno & Spintron), the Comp Cams engineering team left no detail to chance. Everything from casting techniques to valve spring clearance was scrutinized to ensure that the new Ultra Pro Magnum Rocker Arms not only live up to the lofty standards of their predecessor but also took stud mount rocker performance, stability and value to a whole new level. Consider the mission accomplished.

    The most noticeable advancement with the Comp Cams Ultra Pro Magnum Rocker Arms centers around their nearly unbreakable investment cast 8650 chromemoly body. The arched, web-like design delivers a nearly 29% increase in strength and rigidity while reducing the moment of inertia and optimizing the dynamic balance. The resulting rocker maximizes lift and valve train 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. As further testament to the strength of this design, Comp Cams includes a lifetime guarantee against the breakage of the rocker arm body for any reason.

    Even the fit and finish of this innovative new rocker from COMP Cams provides its advantages. The new black oxide exterior finish offers a distinctive appearance along with long term corrosion resistance.

    The Ultra Pro Magnum Rocker Arms from COMP Cams feature an oversized trunion and precision-sorted needle bearings for use with high load valve springs. Additionally, 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. And like the previous generation Pro Magnums, these new rockers feature a fully rebuildable design that means they very well may be the last rocker arms you ever have to purchase.

    **The last 1 or 2 digits in each part number represent the quantity of rocker arms: Ex. 249-1601-12 means 12 rocker arms are included in each order.

    JEGS Easy Kits are designed by JEGS high performance racing professionals to help you get all the performance parts you need for your race car, hot rod or truck.
