Eaton Torque Control Products 914A538 Detroit Truetrac Helical Gear Limited Slip Differential

The Eaton Detroit Truetrac 914A538 is a premium helical gear 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 Truetrac has established itself as the industry-leading solution for drivers who need consistent power transfer without the hassle of regular maintenance.

Key Features:

• Helical gear design eliminates wearable clutch plates and friction discs
• Maintenance-free operation with no fluid additives required
• Smooth, quiet performance under all driving conditions
• Automatically biases torque to the wheel with better traction
• Works seamlessly in both forward and reverse
• No activation threshold—engages progressively as needed
• Ideal for street, off-road, and light racing applications

How It Works:

Unlike traditional clutch-type limited slip differentials, the Detroit Truetrac uses parallel sets of helical gears to transfer torque between axle shafts. When one wheel encounters low traction, the helical gears bind and redirect power to the wheel with grip. This purely mechanical design requires no electronics, clutches, or special maintenance, making it one of the most reliable traction solutions available.

Applications:

The Detroit Truetrac is suitable for a wide range of vehicles including trucks, SUVs, performance cars, and off-road vehicles. Its proven durability and cost-effective performance make it an excellent upgrade from open differentials or worn-out clutch-type units.

Backed by Eaton's engineering expertise and decades of proven performance, the 914A538 Detroit Truetrac delivers the traction you need without the maintenance you don't want.
