Eaton 912A654 Detroit Truetrac Helical Gear Limited Slip Differential

The Eaton Detroit Truetrac 912A654 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 under the Eaton brand, the Truetrac has established itself as the industry-leading solution for drivers seeking dependable performance in varied conditions.

Key Features:

• Helical gear design with no wearable friction plates or clutch packs
• Maintenance-free operation for long-term reliability
• Smooth and quiet performance with no chattering or grabbing
• Automatic torque distribution to the wheel with better traction
• Works seamlessly in normal driving conditions and engages when needed
• Proven durability for street, towing, and light off-road applications

The Detroit Truetrac differential uses helical side gears that automatically transfer torque to the wheel with more grip when traction differences occur. Unlike open differentials that send power to the wheel with least resistance, or aggressive lockers that fully lock both wheels, the Truetrac provides a balanced solution that enhances traction while maintaining predictable handling characteristics. This makes it an ideal upgrade for trucks, SUVs, and performance vehicles where improved grip is needed without compromising daily drivability.
