Tech Insight
Re-gearing your differential changes torque multiplication, acceleration, and overall drivability. Proper gear ratio selection is critical when running larger tires or modifying drivetrain components, as it directly affects engine load and performance.
Accurate installation—including pinion depth, backlash, and bearing preload—is essential for quiet operation and long gear life. Improper setup can lead to premature wear, noise, or gear failure.
