Eaton Detroit Truetrac Differential 30 Spline Rear 11.5in

What you get with this Detroit Truetrac differential is a well-built, helical-gear limited-slip unit designed to significantly improve traction for a wide range of vehicles. This isn't a clutch-based system; instead, it uses gears to automatically send power to the wheel with more grip, making it ideal for everyday driving and more demanding situations alike. It operates smoothly and quietly in both forward and reverse, and it doesn't require any special lubricants or friction modifiers, which simplifies maintenance over the long haul.

The Truetrac is known for its robust construction and its ability to handle the torque demands of many trucks and SUVs. Its design maximizes acceleration and handling by optimizing torque bias ratios, meaning it actively works to keep both wheels driving. This makes it a popular choice for owners looking for a reliable traction enhancement that doesn't come with the noise or wear often associated with other types of limited-slip differentials. It's built to be maintenance-free, so once it's installed, you can largely forget about it and enjoy the improved grip.

This particular unit is for rear axles with 30 splines and an 11.5-inch ring gear diameter, with an axle shaft diameter of 1.55 inches. It's designed to work with all gear ratios for the axles it fits. While it's a versatile unit that fits many vehicles, including models like the Chevrolet Silverado 2500 HD, Dodge Grand Caravan, and GMC Savana 1500, it's crucial to verify fitment for your specific vehicle's rear axle specifications before purchasing.
