ARP SBC Rocker Arm Stud Kit 3/8 (2) 134-7124

Rocker arm studs are critical fastening points that endure constant cyclic loading in high-RPM engine builds. Stock studs frequently fail under performance conditions, leading to valve train instability and potential catastrophic engine damage. ARP's chromoly construction and precise threading specifications eliminate this vulnerability, delivering the reliability required for sustained racing applications.

The ARP SBC Rocker Arm Stud Kit (2) features a 7/16-14 base thread for secure cylinder head mounting and a 3/8-24 top thread for rocker arm attachment. The 1.895-inch effective length is engineered for proper preload and clearance on small-block Chevy platforms. These studs are manufactured from chromoly steel, offering superior tensile strength compared to OEM fasteners while resisting fatigue failure under continuous high-load cycles.

Installation is straightforward—remove old studs and thread new units into the cylinder head. No special fabrication is required for most SBC applications, though torque specifications should be verified against your engine builder's documentation.
