Eaton Torque Control Products 912A686 Detroit Truetrac Helical Gear Limited Slip Differential

The Detroit Truetrac 912A686 is a helical gear-type limited slip differential engineered for reliable traction without the maintenance requirements of traditional clutch-based differentials. 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, automatic torque transfer.

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 everyday driving
• Automatically transfers torque to the wheel with better traction
• Works seamlessly in forward and reverse
• No special additives or fluids required
• Direct replacement for factory open differentials

The Truetrac's helical gear system uses separating forces from the gears themselves to lock up the differential when torque is applied, providing superior traction in slippery conditions while maintaining comfortable street manners. Unlike clutch-type limited slips that degrade over time, the Truetrac's all-gear design delivers consistent performance throughout its service life. This differential is ideal for trucks, SUVs, off-road vehicles, and performance applications where dependable traction is essential.
