Eaton Torque Control Products 917A731 Detroit Truetrac Helical Gear Limited Slip Differential - 2015-2023 Ford Mustang S550

The Eaton Detroit Truetrac 917A731 is a helical-gear limited-slip differential designed specifically for 2015-2023 Ford Mustang S550 models with the 8.8-inch rear axle. This torque-sensing differential automatically transfers power to the wheel with the most traction, providing superior performance in all driving conditions without the maintenance requirements of traditional clutch-type limited-slip differentials.

Key Features:

• Helical gear design provides smooth, automatic operation with no clutches to wear out
• Torque-biasing technology maximizes traction by transferring power to the wheel with better grip
• Works seamlessly with ABS and traction control systems
• Maintenance-free design uses standard gear oil with no special additives required
• Direct replacement for factory open differential in S550 Mustang 8.8-inch rear axles
• Delivers improved acceleration, cornering stability, and all-weather performance
• Made in USA with Eaton's proven differential technology

The Detroit Truetrac operates transparently during normal driving and automatically activates when wheel slip is detected, making it ideal for street performance, track use, and challenging weather conditions. Unlike clutch-type limited-slip differentials, the Truetrac never wears out or loses effectiveness over time, providing consistent performance throughout its service life.
