Eaton is synonymous with automotive differentials.
The company helped coin the term Posi-Traction, and its Detroit Locker is arguably the most-famous of all locking differentials. Eaton earned its reputation for producing innovative, robust, and high-performing differentials during the American muscle car era, when OEMs worked with the company on original equipment differentials.
Over the years, Eaton’s designs have evolved and its product line has expanded. However, many of the questions about differentials — and Eaton differentials in particular — have remained consistent:
What are the fundamental differences between a locker, limited-slip, and open differential?
How do they work?
Which one is right for me?
We caught up with the folks from Eaton and, with help from our friends at Summit Racing, put together some informational videos. They not only cover the ins and outs of some of Eaton’s most popular and iconic diffs, they also include some great background on how they were developed and for which type of application they were intended.
The films on posi, truetrac and locker are excellent info.
