Eaton Torque Control Products 912A616 Detroit Truetrac Helical Gear Limited Slip Differential

The Eaton Detroit Truetrac 912A616 is a helical gear-type limited slip differential that delivers reliable traction without the maintenance requirements of traditional clutch-type differentials. As the original helical gear differential introduced to the automotive aftermarket, the Truetrac has earned its reputation as the industry-leading solution for improved traction and handling.

Key Features:

• Helical gear design with no clutches or friction plates to wear out
• Maintenance-free operation for long-term reliability
• Smooth and quiet performance during normal driving conditions
• Automatic torque biasing that responds to traction conditions
• Works seamlessly with ABS and traction control systems
• Ideal for street, towing, off-road, and performance applications

The Detroit Truetrac uses a unique helical gear tooth design that multiplies engine torque and transfers power to the wheel with better traction. Unlike traditional limited slip differentials that require periodic fluid changes and clutch pack replacement, the Truetrac's gear-driven design operates in standard gear oil and requires no special maintenance. This makes it an excellent choice for daily drivers, work trucks, and recreational vehicles that demand consistent traction without ongoing upkeep costs.

The differential automatically biases torque away from the slipping wheel to the wheel with more grip, providing enhanced control in rain, snow, mud, and uneven terrain. Installation requires no special tools or modifications, fitting into the factory carrier in place of the original open differential.
