Zerk fitting is no good
I recommend this product ONLY IF you have a 1/16th pipe tap. If not you will have a very nice set of A arms with no way to grease the ball joint. Even worse than that its an open hole to the bearing area. I found this out after I installed them of course. I bought the Speedway lower arms a few months back and had a little trouble installing the ball joint but that was it. Maybe save yourself some money and buy the speedway set
There is no thread for the zerk fitting. It will not self tap. I used a 1/4-28, but its far from right since the thread needied is tapered and its a completely different thread count, it just lets me get a little grease in there and keeps the dirt out. Its a shame, everything else is very well done
