Eaton Detroit Truetrac Differential 35 Spline 1.50in Axle Shaft Dia 4.56 & Up Ratio Rear Dana 60

The Detroit Truetrac differential uses a unique helical-gear design to automatically bias torque to the wheel with more grip. This means you get improved traction for acceleration and handling without the jerky engagement you might find in other limited-slip units. It's a maintenance-free unit that works smoothly in both forward and reverse, making it a versatile choice for a wide range of vehicles. This particular Truetrac is built for Dana 60 rear axles, featuring 35 spline axle shafts and designed to work with ring and pinion gear ratios of 4.56 and numerically higher.

This differential is well-built with durable helical gears that operate quietly and smoothly, providing a noticeable improvement in how your vehicle puts power down. Unlike clutch-type limited-slip differentials, the Truetrac doesn't require special friction modifiers or lubricants, and it won't wear out over time from clutch engagement. Its automatic operation means you don't have to do anything special to engage it; it just works, whether you're navigating slippery roads or accelerating hard. This makes it an ideal traction solution for many types of vehicles, from classic muscle cars like the Dodge Charger to work vans like the Chevrolet G20 and GMC Safari.

When installing this differential into your Dana 60 axle, ensure you have the correct ring gear and pinion set for ratios of 4.56 or lower (numerically higher). The 35-spline axle shaft compatibility is crucial for proper fitment. This unit is designed to fit a broad spectrum of vehicles, including many Chevrolet and GMC vans and trucks from the 70s through the 90s, as well as classic Mopar vehicles like the Chrysler New Yorker and Dodge Challenger. Always refer to the manufacturer's installation instructions for specific details related to your axle housing and vehicle.
