I was considering on getting the new traxxas cvds, or getting the ths racing cvds.
I also have the stock shafts and would like to upgrade them, I dont own either so I wouldnt know but they both look like good choices
i had the ths and all the corners on the cups the shaft sits in broke off so they would fall apart all the time. i just instaled the traxxas ones the other day and they look good but iv only used them for one run so im not sure how thell last.
here are 2 pics comparing the 2 brands the silver ones are the traxxas ones and you can see how thw cups (thats broka on the ths) are thicker at the edge .
