Eaton Torque Control Products 915A388 Detroit Truetrac Helical Gear Limited Slip Differential

The Eaton Detroit Truetrac 915A388 is a premium helical gear limited slip differential designed to deliver reliable, maintenance-free traction for demanding automotive applications. 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 drivers seeking superior traction without the hassle of periodic maintenance.

Key Features:

• Helical gear design eliminates clutch packs and other wearable components for truly maintenance-free operation
• Smooth and quiet operation compared to traditional clutch-type limited slip differentials
• Automatic torque biasing action distributes power to the wheel with better traction
• Works seamlessly in both forward and reverse directions
• No special additives or friction modifiers required in gear oil
• Proven durability in street, towing, and light off-road applications

The Detroit Truetrac uses an innovative arrangement of helical gears that allows the differential to sense traction loss and automatically transfer torque to the wheel with more grip. Unlike open differentials that send power to the wheel with the least resistance, or clutch-type limited slips that require periodic rebuilds, the Truetrac provides consistent performance throughout its service life. This makes it an ideal upgrade for trucks, SUVs, and performance vehicles where dependable traction is essential.

Installation requires professional expertise and may necessitate special tools or setup procedures. Consult with a qualified drivetrain specialist to ensure proper fitment and configuration for your specific vehicle application.
