Eaton Torque Control Products 912A557 Detroit Truetrac Helical Gear Limited Slip Differential

The Eaton Detroit Truetrac 912A557 is a helical gear-type limited slip differential that delivers automatic traction without the maintenance requirements of traditional clutch-type units. As the first helical gear differential introduced to the automotive aftermarket, the Truetrac has established itself as the industry standard for reliable, maintenance-free performance.

Key Features:

• Helical gear design eliminates clutch packs and other wearable friction components
• Automatic torque biasing operation sends power to the wheel with better traction
• Smooth, quiet operation with no chattering or noise associated with clutch-type differentials
• Maintenance-free design requires no special lubricants or periodic service
• Durable construction engineered for on-road and light off-road applications
• Works effectively in forward and reverse

The Detroit Truetrac operates by using the separation forces generated by helical gears to bias torque from the spinning wheel to the wheel with traction. This intelligent mechanical design provides superior performance compared to open differentials while maintaining the durability and longevity that has made it the preferred choice for truck, SUV, and performance vehicle applications.
