Eaton Torque Control Products 914A643 Detroit Truetrac Helical Gear Limited Slip Differential

The Eaton Detroit Truetrac 914A643 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 established itself 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 the life of the differential
• Smooth, quiet performance with no chattering or banging
• Automatically transfers torque to the wheel with better traction
• Works seamlessly in all driving conditions, wet or dry
• Compatible with all gear ratios and axle shaft spline counts
• Ideal for street, towing, off-road, and light racing applications

The Detroit Truetrac operates by using helical side gears that separate under load, forcing themselves against the differential case. This creates a resistance to differentiation, allowing torque to be transferred to the wheel with the most traction. Unlike traditional limited slip differentials that rely on wear-prone clutch packs, the Truetrac's gear-on-gear design provides consistent performance throughout its service life with no special additives or periodic maintenance required.
