JEGS Premium '50' Series Roller Rocker Arms

Product images may differ from actual product appearance.

JEGS Premium '50' Series Roller Rocker Arms are one of the strongest, CNC-machined, ratio-accurate, light weight roller rocker arms available. CAD designed with a unique profile for added rigidity to withstand high pressure valve springs and high lift cams. The roller tip on these rockers is 70% larger diameter, and this keeps the wheel centered better on the valve tip. 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. Gold metallic anodized finish with laser etch JEGS logo and the rocker arm ratio on the face. Made in the USA.
