Rocker Stud Puller & Tap Guide

The Rocker Stud Puller & Tap Guide from COMP CAMS is a specialized engine service tool designed for precision work on Chevy V8 and GM V6 cylinder heads. This tool addresses a critical need in modern engine rebuilding and valve train service: safely removing rocker arm studs without damaging the surrounding aluminum casting. Whether you're a professional engine builder, performance technician, or serious DIY enthusiast, this puller ensures clean extraction and proper preparation for stud replacement or repair.

Constructed from hardened steel with cadmium plating, the Rocker Stud Puller & Tap Guide delivers durability and corrosion resistance essential for engine shop environments. The dual-function design simultaneously extracts the rocker stud while serving as a tap guide—this integrated approach eliminates the need for separate tools and ensures accurate thread alignment when installing new studs. The cadmium finish protects against rust and oxidation, extending tool life across multiple engine rebuilds. Compact dimensions (2.8 x 2 x 4.1 inches) and lightweight construction (0.61 lbs) make it easy to store and maneuver in tight engine bay spaces.

This tool is essential for anyone servicing small-block or big-block Chevy engines and modern GM V6 powerplants where rocker stud integrity directly impacts valve train geometry and performance. The tap guide feature prevents cross-threading and ensures perpendicular hole preparation, critical for maintaining proper rocker arm preload and eliminating valve train noise. Installation is straightforward: position the puller on the stud, apply steady pressure or light heat if necessary, then use the integrated guide for tapping new holes at the correct angle and depth. Professional engine shops rely on this tool for warranty-quality work, while enthusiasts appreciate the precision control it provides during complete cylinder head restoration.
