ULT DT Planetary Hub System - Detailed overview

The DT Hub is a patented design, invented in North America and built in Germany. The DT Hub has been in service for well over 20 years of continuous use with upgrades along the way.
Transform your regular stock, new or used single, tandem or tridem class 8 tractors into A ON-DEMAND prime mover or heavy hauler, with a flick of the switch, simply by changing the hubs.
The DT Hub can convert the most common Dana (Eaton) and Meritor axles into planetary axles with an on-demand 3:1 gear reduction. The reduction is activated and controlled with an in-cab switch using existing truck air.
