Ford 9 Inch DETROIT TRUETRAC® Differential
- 28 SPLINE
- 3.25 AND UP
Detroit Truetrac is the only unit currently available to the aftermarket featuring a gear type limited slip design (no clutch or friction plates to wear out). Designed for medium duty 2 & 4 wheel drive applications, positive gear action provides quiet, automatic splitting of torque, without creating the steering problems associated with other available differentials.
The Detroit Truetrac was the first gear type limited slip differential in the industry. The patented design of parallel axis planetary helical gears provide a quiet, automatic splitting of torque. Power transfer goes literally unnoticed by the driver - even in front wheel drive axles.
The Detroit Truetrac performs like an open differential under normal driving conditions and automatically transfers torque to the wheel with better traction when ground conditions warrant. The limited slip responds instantly to torque feedback, anytime, at any speed.
Detroit Truetrac’s are engineered for front and rear axles, semi-floating (C-clip axles) and transfer cases. Proven design, low cost and effective performance all make the Detroit Truetrac limited slip the choice of professionals and traction enthusiasts everywhere.
