Product Details

The COMP Cams Rocker Arm Stud Girdle (also called a rocker stud girdle or valve train stud brace) ties the tops of your rocker arm studs together. This adds rigidity to the valve train and helps keep the studs stable at high RPM and under heavy spring pressure.

Key Features:

  • Links the rocker arm studs across each cylinder head to reduce stud flex and movement
  • Helps maintain consistent valve lash and valve train geometry
  • Designed for performance and racing engines with stud-mounted rocker arms
  • Available in several configurations to suit different engine families and stud sizes, including spring-loaded designs
  • Made by COMP Cams, a respected name in camshafts and valve train components

A stud girdle is a practical upgrade for engine builders who want a stiffer, more stable valve train. Choose the variant that matches your engine's stud size and layout.
