Powertrax GT209533 Grip Pro Limited Slip Differential GM 9.5in 33-Spline 14-Bolt 3.42 Ratio & Up

The Powertrax GT209533 Grip Pro Traction System is a performance limited-slip differential designed for GM 9.5-inch rear axles with 33-spline axles, 14-bolt cover, and 3.42 gear ratio and numerically higher. It delivers the smooth, street-friendly operation of a limited-slip differential combined with the enhanced traction performance of a locking differential — making it an ideal upgrade for daily-driven trucks and SUVs as well as off-road and performance applications.

At the core of the Grip Pro is a 3x2 spiral gear design that delivers progressive, variable traction based on throttle input. This gives the driver precise control over how much traction is applied, making the Grip Pro equally capable in rain, snow, on-road, and off-road conditions. The fully machined, forged steel case provides exceptional strength and long-term durability.
