Detroit Locker 917A730 Truetrac Differential 2011+ Dodge Ram 1500 31 Spline

The Detroit Locker 917A730 Detroit Truetrac is a helical gear limited-slip differential designed specifically for 2011 and newer Dodge Ram 1500 trucks with 31-spline axles. This torque-sensing differential automatically biases torque to the wheel with better traction, providing improved performance in challenging conditions without the harshness or maintenance requirements of a traditional locker.

Key Features:

• Helical gear design provides smooth, automatic operation with no clutches or springs to wear out
• 31-spline configuration for 2011+ Ram 1500 applications
• Torque-biasing action maximizes traction by transferring power to the wheel with grip
• Operates transparently during normal driving with improved cornering characteristics
• No driver activation required - responds automatically to traction conditions
• Maintenance-free design uses standard gear oil
• Allows limited wheel speed differentiation for smooth street driving and turning

The Truetrac differential is ideal for drivers who want improved traction for towing, off-road use, or inclement weather without the harshness of a full locker. Unlike open differentials that send power to the slipping wheel, the Truetrac continuously biases torque to the wheel with traction, providing confident performance on and off the road.
