Product Details

If you're looking to improve traction for your front axle, the Eaton Detroit Truetrac differential is a solid option. This is a helical-gear style limited-slip unit designed to work automatically, meaning it doesn't require special additives or frequent maintenance. It smoothly sends power to the wheel with more grip, whether you're accelerating from a stop or navigating tricky terrain. This particular model is built for front Dana 44 axles with 8.5-inch ring gears and is compatible with axle shafts that are 30-spline and 1.31 inches in diameter, designed for gear ratios of 3.73 and numerically lower.

The Truetrac's design uses a series of gears to bias torque to the wheel that has better traction. This happens automatically and seamlessly, so you don't feel it engaging or disengaging. It operates quietly and smoothly in both forward and reverse, making it a versatile upgrade for a wide range of vehicles. Because it's maintenance-free and doesn't need special friction modifiers, it simplifies installation and ownership. This differential fits a broad spectrum of vehicles, including many Chrysler, Dodge, and Plymouth models from the late 1960s through the early 2000s, offering a significant improvement in driving characteristics for those seeking enhanced grip.

When installing this differential, ensure you have the correct tools and follow the manufacturer's recommended procedures for setting gear backlash and preload. It's designed to fit Dana 44 front axles and works with 3.73 and numerically lower gear ratios. This unit is a popular choice for drivers who want improved traction without the harsh engagement of some other limited-slip designs.
