Description
A quality limited-slip differential is the foundation of predictable, controllable power delivery—especially when you’re pushing your GM 12-bolt to its limits. The Duragrip Posi design locks and unlocks seamlessly to maintain traction during acceleration and cornering while preserving straight-line stability. If you’re running higher power or frequent track time, this upgrade eliminates the torque-steer and inside-wheel spin that plague open differentials.
