Eaton Torque Control Products 917A739 Truetrac Limited Slip Differential for Ford 8.8 Rear

The Eaton Truetrac 917A739 is a helical-gear limited slip differential designed specifically for Ford 8.8-inch rear axles commonly found in F-150 trucks. This advanced traction device uses a patented helical gear design to automatically transfer torque to the wheel with the most traction, providing superior performance in all driving conditions without the use of clutches or friction plates.

Key Features:

• Helical gear design provides smooth, automatic torque transfer without clutches
• No maintenance required - operates in standard gear oil
• Engineered for Ford 8.8-inch rear axle applications
• Ideal for street, towing, off-road, and performance applications
• Compatible with ABS and traction control systems
• Provides excellent traction in rain, snow, mud, and ice
• Lifetime warranty against manufacturing defects

The Truetrac differential operates by using opposing helical gears that separate under load, creating friction against the differential case. This design delivers consistent performance throughout the life of the differential and works equally well at any speed. Unlike traditional limited slip differentials, the Truetrac requires no special additives or periodic maintenance, making it an ideal choice for daily drivers, work trucks, and recreational vehicles alike.
