Product Details

The COMP Cams 4009 Solid Rocker Arm Stud Girdle is engineered to stabilize rocker arm geometry and prevent stud flex on high-performance Chevrolet small block engines. Designed for 265-400 cubic inch SBC engines equipped with 7/16" rocker studs, this girdle ties all the rocker studs together into a single rigid assembly, significantly improving valvetrain stability at high RPM.

Key Features:

  • Precision-machined solid construction for maximum rigidity and durability
  • Reduces rocker stud deflection and flex under aggressive valve spring pressures
  • Compatible with Chevrolet small block 265, 283, 302, 305, 327, 350, and 400 engines
  • Designed specifically for use with 7/16" diameter rocker arm studs
  • Helps maintain consistent valve lash and rocker arm geometry
  • Essential upgrade for racing applications and high-lift camshafts

This stud girdle is a critical component for serious performance builds where valvetrain stability is paramount. By connecting all rocker studs together, it eliminates individual stud movement and ensures consistent valve control even under extreme racing conditions. Ideal for engines running high spring pressures, aggressive cam profiles, or sustained high-RPM operation.

Easy site to use and great prices

It was good quick and eassy

Rather amazing and uneventful service in this day and age. Ordered a Thule bike rack for my Nissan Murano. It was in stock (unusual for high-end specialty products), shipped the next day, and was on my doorstep in a few days (excellent for a 60 lb. large box). I'd buy anything from these people without any reservation. AND, your order is insured - completely superfluous. Oh, and did I mention, the lowest price I could find ANYWHERE, and not by a few dollars - a lot.

Excellent service with the actual stock on hand, shipment was made the next day and a tracking number was provided. I have tried 2 other online supply stores which don't know what they have in stock.
