Eaton Torque Control Products 912A553 Detroit Truetrac Helical Gear Limited Slip Differential

The Eaton Detroit Truetrac 912A553 is a helical gear-type limited slip differential that delivers reliable, maintenance-free traction for demanding automotive applications. As the first helical gear differential introduced to the automotive aftermarket under the Eaton brand, the Detroit Truetrac has established itself as the industry-leading design for smooth, quiet, and dependable performance.

Key Features:

• Helical gear design provides smooth, automatic torque transfer without clutches or plates
• Maintenance-free operation with no wearable components requiring service or adjustment
• Quiet operation compared to traditional clutch-type limited slip differentials
• Automatic torque biasing responds instantly to traction conditions
• Proven durability in street, off-road, and performance applications
• Works with all axle ratios and does not require special additives

The Detroit Truetrac differential uses parallel helical gears to bias torque automatically to the wheel with better traction. Unlike clutch-type limited slips that wear over time, the Truetrac's gear-on-gear design maintains consistent performance throughout its service life. This makes it an ideal traction solution for trucks, SUVs, muscle cars, and off-road vehicles where reliable power delivery is essential.
