Eaton Detroit Truetrac Differential 29 Spline 1.21in Axle Shaft Dia 2.73 & Up Ratio Rear 8.375in

Eaton is well-known for their drivetrain components, and their Detroit Truetrac differential is a popular choice for drivers looking to improve traction. This helical-gear limited-slip differential is designed to maximize wheel traction and enhance driving characteristics, making it a versatile solution for a wide range of vehicles. It works automatically in both forward and reverse, providing smooth and quiet operation without needing any special lubrication or friction modifiers.

The Truetrac uses a unique helical gear design that biases torque to the wheel with more grip. This means you get improved acceleration and handling, especially when one wheel might lose traction. It's built for durability and is maintenance-free, so once it's installed, you can largely forget about it. This differential fits rear axles with an 8.375-inch ring gear and is compatible with axle shaft diameters of 1.21 inches and 29 splines, suitable for ratios of 2.73 and up. It's a solid option for vehicles like the Dodge Grand Caravan, Chrysler PT Cruiser, or Dodge Ram 1500, among many others.

When installing this differential, it's important to follow the manufacturer's instructions carefully, as it typically requires setting up gear backlash and checking pattern. While this unit is designed for smooth and quiet operation, proper installation is key to achieving that. You'll want to ensure you have the correct tools and potentially a service manual for your specific vehicle to complete the job correctly.
