Eaton Detroit Truetrac Differential 35 Spline 1.52in Axle Shaft Dia 3.73 & Down Ratio Rear Dana 80

Starting with its helical gear design, the Eaton Detroit Truetrac differential is built to maximize wheel traction and improve your vehicle's driving characteristics. This isn't a clutch-based limited-slip that can wear out or chatter; instead, it uses gears to automatically send power to the wheel with more grip, whether you're moving forward or in reverse. It's a maintenance-free unit that doesn't require any special fluids or friction modifiers, making it a versatile traction solution for a wide range of vehicles, including many Chrysler, Dodge, and Ford models.

The Truetrac's internal helical gears are well-known for their smooth, quiet operation, which is a significant upgrade over some other limited-slip designs. This differential is engineered to handle the demands of daily driving and more spirited use, providing consistent performance without the harsh engagement sometimes associated with traction-enhancing differentials. Its design is optimized for torque bias ratios that help deliver better acceleration and handling, making it a popular choice for those looking to improve their vehicle's grip in various conditions.

This specific model is designed for Dana 80 rear axles and features 35 spline axle shafts with a 1.52-inch diameter. It's intended for use with ring and pinion gear sets with a ratio of 3.73 or numerically lower (e.g., 4.10, 4.56). When installing, ensure you have the correct setup for your Dana 80 axle, as proper gear pattern and backlash are crucial for any differential installation. This unit is a solid option for improving traction without sacrificing daily drivability.
