Eaton Detroit Truetrac Differential 33 Spline 1.41in Axle Shaft Dia 3.08-3.90 Ratio Rear 8.875in

The Eaton Detroit Truetrac differential uses a helical-gear design to automatically bias torque to the wheel with more grip. This means you get improved acceleration and handling, especially when one wheel might lose traction, like on uneven surfaces or during spirited driving. It's built to work smoothly and quietly in both forward and reverse, and it doesn't require any special fluids or friction modifiers, making it a maintenance-free traction solution for a wide range of vehicles. This particular unit is designed for rear axles with an 8.875-inch ring gear, 33-spline axles, and compatible with gear ratios from 3.08 up to 3.90.

This differential is a solid choice for many classic muscle cars and trucks, fitting vehicles like the 1964-1972 Chevrolet Impala, 1967-1972 Chevrolet Camaro, and 1964-1972 Oldsmobile 98. Its robust helical gear design is known for its durability and smooth operation, providing enhanced traction without the harsh engagement or noise sometimes associated with other types of limited-slip differentials. Because it operates automatically, you don't have to do anything special to engage it; it just works, improving your vehicle's ability to put power down in various conditions.

When installing this differential, you'll want to ensure your axle housing is clean and that you have all the necessary installation components, such as bearings and seals, which are typically sold separately. Refer to the manufacturer's installation instructions for detailed guidance on setup and proper gear pattern checking. This Truetrac is designed to be a direct replacement for your factory differential, simplifying the installation process for mechanics and experienced DIYers alike.
