I did a search, seems most are going with Spicer. Has anyone used the torq king u joints from quad4x4? Yes, they seem pretty pricey but are they worth it?
All my u joints are the original ones and I think it's time to change them out.

 

Spicer sealed units, no zerk. They are stronger than the zerked ones and are a direct replacement. I got 88K out of the stockers.
