If you’re building a GM truck or car from the 1980s or newer and want your steering to feel tight, responsive, and modern, PSC’s Pro Touring Series Gear is the upgrade for you. With a 12.7:1 quick ratio, this gear gives you firmer handling and better road feel—perfect for street builds, tow trucks, or anything with aftermarket performance parts.

Choose between a Zinc Plated Casting for corrosion resistance or a Black Painted Casting for a clean, OE-style look. Either way, you’re getting a PSC-built gear with upgraded internals, billet components, and a direct bolt-in fit for GM vehicles with a 3/4-30 spline input shaft.
