The Detroit Truetrac was the first helical gear differential ever introduced into the automotive aftermarket as an Eaton brand. It remains the leading helical gear-type limited slip differential in the industry. Detroit Truetrac''s proven helical gear design eliminates the need for wearable parts, resulting in maintenance free traction recognized not only for its toughness, but its smooth and quiet operation as well.Proven design, low cost and effective performance all make the Detroit Truetrac limited slip differential the ideal choice for a wide variety of vehicle applications. No maintenance - Just Traction.
Detroit Truetrac® Differential; 30 Spline; 1.30 in. Axle Shaft Diameter; 3.73 And Up Ring Gear Pinion Ratio; Also Fits GM Half Ton Truck;
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.
