Product Details

COMP Cams stud girdle adjusting nuts, also called stud girdle polylocks or rocker arm adjusting nuts, are made for rocker arm setups that use a stud girdle. Each nut comes with a snap ring that holds the girdle bar in place. They let you set valve lash accurately and lock it in place.

Key Features:

  • Strong locking design: Built for strength and locking force in the valvetrain.
  • Precision ground: Ground for minimum runout and tapered in the locking area for extra strength.
  • Stud girdle compatible: Made to work with stud girdle systems, with snap rings that hold the girdle bar.
  • Adjustable valvetrain: Lets you adjust valve lash on rocker arms that use a polylock-style nut.
  • Multiple options: The line is offered in several stud sizes and in single-nut and multi-piece configurations.
  • Made in the USA: Made by COMP Cams, a respected name in performance valvetrain components.

Stud girdles help keep the rocker studs stable under high spring pressure and high RPM. These adjusting nuts are a dependable choice for street performance and racing engine builds.
