Eaton Torque Control Products 911A319 Detroit Truetrac Helical Gear Limited Slip Differential

The Eaton Detroit Truetrac 911A319 is a helical gear-type limited slip differential designed to deliver reliable traction without the maintenance requirements of traditional clutch-type units. As the first helical gear differential introduced to the automotive aftermarket under the Eaton brand, the Truetrac has established itself as the industry-leading solution for consistent, automatic torque biasing.

Key Features:

• Helical gear design eliminates wearable clutch packs and friction plates for maintenance-free operation
• Automatically transfers torque to the wheel with better traction when wheel slip occurs
• Smooth, quiet operation with no chattering or binding during normal driving
• Works effectively in forward and reverse
• No special additives or friction modifiers required in gear oil
• Proven durability in demanding on-road and off-road applications

The Detroit Truetrac operates by using the separation forces of helical gears to create a torque bias between the two axle shafts. Unlike open differentials that send power to the wheel with least resistance, the Truetrac continuously redistributes torque to the wheel with the most traction. This happens automatically and seamlessly, providing superior performance in wet, icy, or loose terrain without driver intervention.

Ideal for trucks, SUVs, and performance vehicles where dependable traction is essential, the Truetrac offers an excellent balance of cost-effectiveness, longevity, and real-world performance. Installation requires no special tools beyond standard differential setup equipment.
