Eaton Detroit Truetrac Differential 35 Spline 1.50in Axle Shaft Dia 4.10 & Up Ratio Rear Dana 80

This is the Eaton Detroit Truetrac differential, a helical-gear limited-slip unit designed to significantly improve traction for a wide range of vehicles. If you're looking to get more grip from your rear axle, especially in situations where one wheel might lose contact with the ground, this differential is a solid choice. It works automatically, meaning you don't have to do anything special to engage it; it senses wheel speed differences and biases torque to the wheel with more grip. This unit is built for Dana 80 rear axles and is compatible with axle shaft diameters up to 1.50 inches and gear ratios of 4.10 and numerically lower.

What sets the Truetrac apart is its maintenance-free operation. Unlike some other limited-slip differentials, it doesn't require special friction modifiers or fluids, making installation and upkeep much simpler. The helical gear design ensures smooth, quiet engagement and operation, whether you're accelerating forward or in reverse. This makes it a versatile option for daily drivers, work trucks, or even off-road applications where consistent traction is key. It's a well-built unit that provides a notable improvement in acceleration and handling by ensuring both rear wheels are working together effectively.

This differential is designed to fit a broad spectrum of vehicles, including many Dodge Ram trucks and vans, Ford E-Series vans and trucks, and even some Chrysler and Plymouth minivans from the mid-90s to the mid-2000s. When installing, ensure you have the correct tools and follow the manufacturer's guidelines for setting gear backlash and preload to ensure optimal performance and longevity. It's a significant upgrade for any vehicle that could benefit from improved traction without the drawbacks of a fully locking differential.
