Scorpion’s Endurance Series shaft-mount rocker arms smoothly transfer camshaft motion to the valve by properly positioning the rocker over the valve. A stable valvetrain means better performance and more horsepower potential. Since the rockers are mounted on a single horizontal shaft rather than separate studs that are prone to flexing, valvetrain stability is improved considerably.

Made in the USA, Scorpion Endurance Series shaft mount rocker arms are fully CNC machined and feature:

  • Fully radiused rocker bodies made from 7000 series aluminum

  • Needle bearing fulcrum and roller tip

  • .562 inch diameter centerless ground shafts
  • .625 inch adjuster engagement
  • Total weight of each assembled rocker arm: 120 grams

• Blue anodized rocker arms, black oxide-coated steel
