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. 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.

Manufactured from premium aircraft-grade alloy steel, these studs are 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 rocking or micro-movement that can compromise valve timing accuracy and increase wear on rocker arms and pushrods.

This rocker arm stud kit is indispensable for mechanics rebuilding vintage Chevy big-blocks, LS-series engines, or small-blocks destined for high-performance builds. The straightforward installation process allows users to easily replace old studs with new ones, making it an ideal choice for engine refreshes or head work.
