Eaton Detroit Truetrac Differentials
Eaton Detroit Truetrac differentials use a patented design of parallel-axis planetary helix gears to provide a quiet, automatic splitting of torque. They perform like a limited-slip differential under normal driving conditions, automatically transferring torque to the wheel with better traction when ground conditions warrant. These replacement units are available for dozens of axle applications.
Eaton differentials require special bearings. For 1999 and prior- bearing LM102949 and race LM102911 are required. (2.89 O.D. race) For applications 1999 and newer with race O.D. of 3.06 in. bearing LM603049 and race LM603012 are required.
Special Attention:
Eaton recommends a petroleum/mineral based GL-5 80W90 gear oil for all Truetrac differentials. Do not use synthetic gear oil or friction modifiers.
