Dynatrac is one of the most trusted names in aftermarket drivetrain products. So when owner Jim McGean decided to reinvent the Dana 60 locking hub, he knew he had high standards to uphold. As such, Jim invested a considerable amount of resources in the project. After nearly two years of research and development, the Dynaloc was born. Not just another typical locking hub, the Dynaloc is built tough and designed to handle three times the torque of a regular Dana 60 hub. It also features a patent-pending fail-to-lock feature that won't leave you stranded in two-wheel drive should a hub ever break on the trail or during competition. We like them because they are super-easy to install, even simpler to operate, and they come backed by a 5-year guarantee against breakage. Take a look at how easy these stout new hubs are to install.
