COMP Cams 4004B-1 Stud Girdle Bar for Cylinder Heads

The COMP Cams 4004B-1 is a single stud girdle bar designed to stabilize rocker arm studs under high-performance engine applications. This precision-engineered component helps prevent stud deflection and rocker arm instability during aggressive valve train operation, particularly in racing and high-RPM street performance builds.

Key Features:

• Connects and stabilizes rocker arm studs to reduce flex and movement
• Helps maintain proper valve train geometry under extreme loads
• Manufactured from high-strength steel for durability
• Direct replacement for COMP Cams valve train systems
• Individual bar allows for custom stud girdle configurations

Stud girdle bars are essential components for engines operating at elevated RPM ranges or with high-ratio rocker arms and aggressive camshaft profiles. By tying rocker studs together, this girdle bar minimizes stud pullout risk and ensures consistent valve lash throughout the RPM range, improving valve train reliability and performance.
