Eaton Torque Control Products 915A387 Detroit Truetrac Helical Gear Limited Slip Differential

The Eaton Detroit Truetrac 915A387 is a helical gear-type limited slip differential that delivers reliable traction without the maintenance requirements of traditional clutch-type differentials. As the first helical gear differential introduced to the automotive aftermarket, the Truetrac has established itself as the industry-leading design for smooth, automatic traction control.

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 compared to clutch-type limited slips
• Automatically transfers torque to the wheel with better traction
• No special additives or fluid changes required
• Ideal for street, towing, and light off-road applications

The Detroit Truetrac uses a parallel axis helical gear design that automatically biases torque to the wheel with the most traction. Unlike clutch-type limited slips that degrade over time, the Truetrac's all-gear design ensures consistent performance throughout its service life. This differential operates transparently during normal driving and automatically engages when traction is needed, making it an excellent choice for drivers who want dependable traction without the harshness or noise of a locker.
