Eaton Detroit Truetrac Differential 30 Spline 1.31in Axle Shaft Dia 3.92 & Up Ratio Rear Dana 44

The Detroit Truetrac differential uses a helical gear design, which means it's always working to send power to both wheels. Unlike some other limited-slip units, this one doesn't need special fluids or friction modifiers, making maintenance straightforward. It operates smoothly and quietly in both forward and reverse, and it's built to handle a wide range of vehicles, from classic Ford Broncos and Jeeps to later model Cherokees and Wranglers.

This unit is designed for Dana 44 rear axles and features 30 splines with a 1.31-inch axle shaft diameter. It's intended for use with gear ratios of 3.92 and numerically higher. The helical gears inside are well-built and engage automatically as soon as they detect a difference in wheel speed, giving you improved acceleration and handling without any sudden jerks or noises. This makes it a solid choice for daily drivers and off-road adventurers alike who want more consistent traction.

When installing this differential, ensure you have the correct tools and refer to the manufacturer's service manual for detailed instructions. Because it's a limited-slip unit, it's a significant upgrade for vehicles that see varied traction conditions, helping you get moving more reliably.
