Product images may differ from actual product appearance.

JEGS Premium '50' Series Rocker Arms are one of the strongest, CNC-machined, ratio-accurate, light weight rocker arms available. CAD designed with a unique profile for added rigidity to withstand high pressure valve springs and high lift cams. Clearanced for 1.625" spring and retainer combinations. You can expect 15+ horsepower just by bolting these on vs. stamped O.E. rockers, plus you'll increase your rpm range thanks to our lightweight construction.
