Whether you are tackling rocky trails or navigating wet pavement, the Truetrac provides smooth, automatic torque biasing to ensure power is always delivered to the wheels with the most traction.

  • Helical-Gear Technology: Provides seamless, chatter-free operation without the need for clutches or friction modifiers.
  • Automatic Bias: Instantly reacts to changing terrain, providing consistent power delivery.
  • Maintenance-Free: Built to last, requiring no special additives or frequent rebuilds.
  • Wide Ratio Compatibility: Works perfectly with gear ratios from 3.54 to 5.29.

This differential is a perfect upgrade for Toyota 4Runner, Tacoma, Tundra, and Celica models, offering a significant boost in handling and off-road capability. The helical-gear design ensures that you get the benefits of a locker without the harsh engagement often associated with mechanical locking differentials. It is the ideal choice for drivers who want a reliable, daily-drivable traction aid that performs when the going gets tough. With its precision-machined gears and robust housing, the Truetrac is built to handle the torque demands of modified engines and larger tires.
