Product Details

The COMP Cams 4001 spring-loaded rocker arm stud girdle is engineered to stabilize rocker arm studs on Chevrolet small block engines (265-400 cubic inch). This girdle system reduces stud flex and prevents stud pull-out under high valve spring pressures, making it essential for performance builds with aggressive cam profiles and high-RPM operation.

Key Features:

  • Spring-loaded design maintains constant pressure on rocker studs
  • Fits Chevrolet small block 265, 283, 302, 305, 307, 327, 350, and 400 cubic inch engines
  • Compatible with 3/8" diameter rocker arm studs
  • Prevents stud walk and reduces stud flexing under high loads
  • Improves valve train stability for high-performance applications
  • CNC-machined construction for precise fitment and durability

This stud girdle is particularly beneficial for engines running high-lift camshafts with elevated spring pressures, where rocker stud integrity is critical for maintaining proper valve train geometry and preventing costly failures. The spring-loaded design ensures consistent clamping force across all rocker studs, even as components settle during break-in and operation.
