Product Details

The COMP Cams 4509S-1 is a precision-engineered stud girdle adjusting nut designed specifically for use with 3/8" rocker arm studs. This adjusting nut features an integrated snap ring groove for secure retention, making it ideal for high-performance applications where maintaining proper valve train geometry is critical.

Key Features:

  • Designed for 3/8" diameter rocker arm studs
  • Integrated snap ring groove provides positive retention and prevents loosening
  • Compatible with stud girdle systems for enhanced valve train stability
  • Manufactured from high-quality materials for durability under extreme conditions
  • Allows precise valve lash adjustment while securing the stud girdle

This adjusting nut is essential for engines using stud girdle systems, which help reduce rocker arm stud flex and improve valve train control at high RPM. The snap ring design ensures the nut stays securely in position during operation, making it a reliable choice for racing and high-performance street applications.
