Eaton Detroit Truetrac Differential 27 Spline 1.15in Axle Shaft Diameter 3.73 & Up Ratio Dana 30

If you're looking to improve traction and handling in your vehicle, this Eaton Detroit Truetrac differential is a solid choice. It's a helical-gear style, limited-slip unit designed to work automatically, sending power to the wheel with the most grip whether you're moving forward or in reverse. This makes it a versatile solution for a wide range of vehicles, including many Volvo models like the 240, 242, and 245, as well as others with a Dana 30 rear axle and a 3.73 or numerically lower gear ratio.

What sets the Truetrac apart is its maintenance-free operation. Unlike clutch-type limited-slip differentials, it doesn't require special lubrication or friction modifiers, and it operates smoothly and quietly. The helical gear design provides optimized torque bias ratios, which means you'll see improved acceleration and handling, especially when you need it most. It's a well-built unit that's designed for durability and long-term performance without the need for constant upkeep.

This differential is specifically designed for axles with 27 splines and a 1.15-inch axle shaft diameter, fitting Dana 30 applications with gear ratios of 3.73 and up. When installing, remember to consult the manufacturer's instructions for specific details regarding your vehicle's setup. It's a significant upgrade for anyone seeking enhanced grip and a more confident driving experience.
