Eaton Detroit Truetrac Differential 31 Spline 1.32in Axle Shaft Diameter 3.25 & Up Ratio

The helical gears inside this Detroit Truetrac differential are designed to provide optimized torque bias ratios, which means you get maximum acceleration and handling. This unit is built for a 31-spline axle and works with axle shafts that are 1.32 inches in diameter, and it's compatible with ring and pinion gear ratios of 3.25 and up. It's a maintenance-free limited-slip unit that operates smoothly and quietly in both forward and reverse, making it a versatile traction solution for a wide range of vehicles.

Unlike some other traction-enhancing differentials, the Truetrac doesn't require any special lubrication or friction modifiers, simplifying maintenance and reducing ongoing costs. Its automatic engagement means you don't have to do anything; it just works, providing consistent power to both wheels when needed. This makes it an ideal choice for daily drivers, trucks, and even some performance applications where improved traction is a priority without the noise or harshness sometimes associated with other limited-slip designs. It fits a broad spectrum of vehicles, including many Ford trucks and SUVs like the Bronco and E-Series vans, as well as various Jeep models.

When you're looking to improve your vehicle's ability to put power down, especially in slippery conditions or during hard acceleration, the Detroit Truetrac is a solid option. It's a well-built unit that offers a significant improvement in traction over an open differential, all while maintaining a comfortable driving experience. You'll find it's a popular choice for those who want enhanced performance without sacrificing daily drivability.
