Eaton Detroit Truetrac Differential 28 Spline 1.20in Axle Shaft Diameter 2.73 & Up Ratio Rear 8.5in

Eaton is well-known for their 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 maximize wheel grip, making it a solid option for a wide range of vehicles, from classic muscle cars like the 1970-1972 Chevrolet Chevelle to more modern trucks and SUVs like the 1977-1986 Chevrolet C10. It works automatically in both forward and reverse, providing smooth and quiet operation without needing special lubricants or friction modifiers.

The Truetrac's design uses helical gears to bias torque to the wheel with more grip, enhancing acceleration and handling. This means you get improved performance whether you're navigating slippery roads or pushing your vehicle a bit harder. It's a maintenance-free unit, so once it's installed, you can generally forget about it and enjoy the benefits of improved traction. This differential is built for an 8.5-inch rear axle and is designed for vehicles with a 2.73 and up ring gear pinion ratio, with 28 splines and a 1.20-inch axle shaft diameter.

When considering a differential upgrade, the Detroit Truetrac offers a versatile and reliable solution. It's an ideal traction enhancement for many different types of vehicles, providing a noticeable improvement in how your vehicle puts power down to the road. Ensure your rear axle housing is the 8.5-inch size and that your gear ratio is 2.73 or numerically higher for proper fitment.
