Eaton Torque Control Products 911A415 Detroit Truetrac Helical Gear Limited Slip Differential

The Detroit Truetrac 911A415 is a helical gear-type limited slip differential that provides reliable traction without the maintenance requirements of traditional clutch-based designs. 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 smooth, quiet, and dependable performance.

Key Features:

• Helical gear design eliminates clutch packs and other wearable friction components
• Maintenance-free operation with no periodic service requirements
• Smooth and quiet engagement compared to traditional limited slip differentials
• Provides continuous power transfer to both wheels for improved traction
• Automatically biases torque to the wheel with better grip
• Durable construction suitable for street, towing, and off-road applications
• Works seamlessly with ABS and traction control systems

The Truetrac differential uses inverted tooth geometry that allows the gears to climb over each other under load, creating a separating force that applies pressure to the side gears. This design automatically transfers torque to the wheel with the most traction, ensuring both wheels contribute to forward motion. Unlike open differentials that send power to the wheel with least resistance, the Truetrac maintains power delivery even when one wheel encounters slippery conditions.

This proven design offers an ideal balance of performance, durability, and value for a wide range of vehicle applications where consistent traction is essential.
