Eaton Detroit Truetrac Differential 27 Spline 1.18in Axle Shaft Dia 3.54 & Up Ratio Rear Dana 35

If you're looking to get more grip from your rear axle, especially when you're off-road or dealing with slippery conditions, the Eaton Detroit Truetrac is a solid choice. This isn't your typical open differential; it's a helical-gear limited-slip unit that automatically sends power to the wheel with the most traction. It works seamlessly in both forward and reverse, making it a versatile upgrade for a wide range of vehicles like the Jeep Cherokee, Wrangler, and Grand Cherokee, among others.

What sets the Truetrac apart is its smooth, quiet operation. Unlike some other limited-slip designs that can chatter or require special fluids, this unit uses a clever gear system to bias torque. This means no special lubrication or friction modifiers are needed, and it's virtually maintenance-free. The helical gears are well-built and designed for durability, ensuring consistent performance whether you're crawling over rocks or just navigating a wet highway. It's engineered to work with axle ratios of 3.54 and numerically higher, and it's designed for axles with 27 splines and 1.18-inch diameter axle shafts, commonly found in Dana 35 rear ends.

When installing this differential, remember it's designed for Dana 35 rear axles and requires specific setup procedures to ensure proper function and longevity. It's a significant upgrade that changes how your vehicle handles under load and in low-traction situations. You'll notice improved acceleration and more confident handling, especially when one wheel might lose grip.
