Eaton Detroit Truetrac Differential 33 Spline 1.37in Axle Shaft Diameter Front 9.25in Rear 9.5in

Eaton is well-known for their performance drivetrain components, and the Detroit Truetrac differential is a popular choice for drivers looking to improve traction. This helical-gear style, limited-slip differential is designed to automatically send power to the wheel with the most grip, enhancing your vehicle's acceleration and handling without any driver input. It works seamlessly in both forward and reverse, making it a versatile upgrade for a wide range of trucks and SUVs, including models like the Chevrolet Astro, Avalanche, and C1500.

Unlike some other limited-slip differentials, the Truetrac requires no special lubrication or friction modifiers, meaning it's maintenance-free and operates smoothly and quietly. Its internal helical gears engage automatically when traction loss is detected, providing consistent and reliable performance. This makes it an ideal solution for improving your vehicle's ability to handle slippery conditions, heavy loads, or challenging terrain. The 33-spline design and 1.37-inch axle shaft diameter are key specifications to ensure it pairs correctly with your vehicle's axle setup.

This differential is a solid option for those who want improved traction without the drawbacks of automatic locking differentials. It offers a noticeable improvement in how your vehicle puts power down, especially when you encounter situations where one wheel might lose grip. When installing, ensure you follow the manufacturer's guidelines for proper setup and any required gear oil specifications to get the most out of its smooth and quiet operation.
