You can run them...but there are better choices for a DD.
You can run full width 1tons on links and full hydro with no flares/roof/windshield...but there are better choices for a DD.
I don't need a degree and scientific data to know that 2 metal surfaces separated by a bearing with grease will wear In a DD better than the 2 metal surfaces separated by grease alone...but the recommendations of the u-joint manufacturers helps. Yukon lists them as "off road only", :rtm:
Buy what you like, and enjoy. If you take care to maintain them all the time, they will likely serve you well...but I wouldn't recommend them for a DD, and I feel they are a complete waste when a Spicer 5-760x is already capable of breaking a 27 spline cromo:greensmok
