SKU: 917A738
The Eaton Detroit Truetrac Differential (Part Number: 917A738), a helical-gear limited-slip unit designed specifically for the front 8.8-inch independent front suspension (IFS) axle. This differential delivers consistent torque distribution to both wheels, ensuring reliable power transfer during acceleration, cornering, and low-traction scenarios like off-road trails, snow-covered roads, or heavy towing. Unlike traditional open differentials that send power to the wheel with the least resistance, the Truetrac's gear-based system automatically biases torque up to 5:1 to the wheel with grip, reducing wheel spin and maintaining forward momentum without the chatter or wear associated with clutch-type units. Built with durable steel construction and precision-machined helical gears, it operates quietly and requires no maintenance, making it a dependable addition for daily drivers and enthusiasts who demand traction without compromise.
