🔧 Why You Need This Tool

In high-torque Barra builds, even ARP bolts can loosen or shear over time — especially in automatic applications. Dowelling the crank locks the crank to the flexplate for unmatched rotational security. Until now, that meant pulling the engine and risking misalignment.

This tool changes the game. Built to Atomic’s precision standards, it allows you to do the job in-car, correctly, and without hassle. A must-have for any serious Barra builder or workshop.
