Control Arms Upgrades
They don't have a jam nut on the adjustment thread.
I bought Claytons both upper and lower front and rear. I would look at other options if I had to buy again. Johnnie joints are wearing quickly (15k miles), don't accept grease very well, zirks don't seem to work very well (and I have replaced once). Also the upper rears are really thick near the tire. Not sure if other brands are similar. When I was using the stock wheels and 285's I had to use spacers.
I have an another question, from the JKS CAs picture, I see them are very different from other adjustable CAs, in fact, the JKS CAs look like "shocks" to me, so how do they lock the position for the length?
