GM Rocker Arm Stud Kit (12)

The GM Rocker Arm Stud Kit (12) by ARP is an essential upgrade for any serious engine builder or performance mechanic working on General Motors small-block and big-block applications. Rocker arm studs are the critical fastening points that secure rocker arm assemblies to the cylinder head, and factory studs often fail under high-RPM conditions, excessive valve spring pressure, or aggressive cam profiles. This 12-piece kit replaces worn or damaged studs with premium ARP hardware designed to eliminate flex and ensure consistent rocker geometry across your entire valvetrain.

ARP manufactures these studs from premium aircraft-grade alloy steel, hardened and shot-peened to provide superior strength and fatigue resistance compared to OEM replacements. The precise thread geometry and head design ensure proper seating and eliminate the rocking or micro-movement that compromises valve timing accuracy and increases wear on rocker arms and pushrods. Each stud in this kit meets strict ARP quality standards and is individually inspected, making it suitable for both naturally aspirated and forced-induction engines running elevated boost or nitrous. The kit's straightforward installation—simply remove the old studs and install new ones with appropriate torque specifications—makes it an ideal choice for engine refreshes, head work, or high-performance builds.

This rocker arm stud kit is indispensable for mechanics rebuilding vintage Chevy big-blocks, LS-series engines, or small-blocks destined for track duty or street performance applications where valve actuation reliability is non-negotiable. Whether you're restoring a classic muscle car, upgrading a worn engine, or assembling a race-ready combination, the GM Rocker Arm Stud Kit (12) by ARP delivers the durability and precision required to keep your valvetrain operating at peak efficiency. Compatible with standard GM cylinder heads from the 1950s through modern production engines, this kit represents a cost-effective insurance policy against catastrophic valvetrain failure and ensures years of dependable high-RPM performance.
