Eaton Detroit Truetrac Differential 26 Spline 1.16in Axle Shaft Diameter 3.23 & Up Ratio

What you get with this Eaton Detroit Truetrac differential is a helical-gear limited-slip unit designed to significantly improve traction for a wide range of vehicles. It's built to work automatically, meaning it engages smoothly without you having to do anything, whether you're moving forward or in reverse. This makes it a versatile solution for many different types of cars and trucks, from classic muscle cars like the Chevrolet Camaro to everyday drivers like the Buick LeSabre and Chevrolet Caprice.

The Truetrac uses a unique, gear-based design that biases torque to the wheel with more grip, helping you accelerate and handle better, especially in slippery conditions. Unlike some other limited-slip differentials, this one doesn't require any special lubrication or friction modifiers, which simplifies maintenance and keeps operation quiet and smooth. Its robust construction means it's built to last, providing reliable performance for years to come. This differential is specifically designed for rear axles with a 7.5-inch ring gear diameter, 26 spline count, and a 3.23 or numerically higher gear ratio.

When installing this differential, it's important to ensure your axle housing is the GM 7.5-inch type and that your ring and pinion gears are set up correctly with the proper backlash and pattern. Because this is a limited-slip unit, it's a significant upgrade for vehicles that came with an open differential, offering a noticeable improvement in grip without the harsh engagement sometimes found in other traction systems. You'll want to make sure you have all the necessary installation components, such as bearings and seals, before you begin the job.
