Eaton Detroit Truetrac Differential 31 Spline 1.32in Axle Shaft Dia Front 8.8in/Reverse Rear 8.8in

What you get with this Eaton Detroit Truetrac differential is a well-built, helical-gear limited-slip unit designed to significantly improve traction for a wide range of vehicles. This differential operates smoothly and quietly, automatically sending power to the wheel with the most grip, whether you're accelerating or braking, and it works just as effectively in forward and reverse. It's a maintenance-free unit, meaning no special lubrication or friction modifiers are needed, making it a straightforward upgrade for many trucks, vans, and SUVs.

The Truetrac is a popular choice because it offers a noticeable improvement in acceleration and handling without the harsh engagement or noise sometimes associated with other traction-enhancing differentials. Its helical gear design is inherently durable and built for long service life. With 31 splines and a 1.32-inch axle shaft diameter, it's engineered to handle increased torque demands, making it suitable for vehicles that see regular use or are used for towing and hauling. This differential is designed to fit 8.8-inch Ford axles, both front and rear (in reverse applications), and is compatible with a vast array of Ford models from the mid-80s through the early 2010s, including popular choices like the Ford Bronco, F-150, and E-Series vans.

When installing this differential, it's important to follow the manufacturer's instructions carefully, as it requires setting up gear patterns and backlash just like a standard open or limited-slip differential. While it doesn't require special fluids, ensuring proper installation is key to its smooth, quiet, and reliable operation. This unit is a solid option for anyone looking to enhance their vehicle's ability to put power down, especially in slippery conditions or during spirited driving.
