Eaton Detroit Truetrac Differential 30 Spline 1.31in Axle Shaft Dia 3.73 & Down Ratio Rear Dana 44

If you're looking to improve traction for your Dana 44 rear axle, the Eaton Detroit Truetrac differential is a solid choice. This helical-gear limited-slip unit is designed to maximize grip by automatically sending torque to the wheel with the most traction, whether you're accelerating forward or reversing. It works seamlessly without needing special fluids or friction modifiers, making it a maintenance-free upgrade for a wide range of vehicles, including classic Ford Broncos, Jeep Wranglers, and even some International Scout models.

What sets the Truetrac apart is its smooth, quiet operation. Unlike some other traction-enhancing differentials that can be noisy or grabby, the Truetrac's helical gears engage progressively, providing consistent power to both wheels. This means you get improved acceleration and handling without sacrificing daily drivability. It's built with durable components to handle the demands of various driving conditions, from daily commuting to off-road adventures. The unit is designed for axles with 3.73 or numerically lower gear ratios and requires 30-spline axle shafts with a 1.31-inch diameter.

When installing this differential, ensure you have the correct tools and refer to the manufacturer's installation instructions for proper setup. This unit is designed to fit a variety of Dana 44 applications, so double-checking your axle spline count and ratio is key. It's a well-built component that offers a significant improvement in traction and driving confidence for many popular trucks and SUVs.
