Truetrac Differential Information
The Tractech “Truetrac” Limited Slip differential is a parallel axis planetary helical type limited-slip differential. When the
vehicle experiences unequal side-to-side traction, the pinions resist rotation in the case and transfer torque from one side
gear to the other.
Note: Under curtain operating conditions customers may experience light noise and/or a mild shudder, which is normal.
