I have to say I do not like them, did not like what I saw when I fitted them for Alex and after seeing Pete's drop off and examining the parts am even more convinced they are bad news, the weak point is the bolt, the taper in the arm has been bored out to parallel then due to constraints with the joint design a spacer tube is inserted so the bolt does not wobble about, and here is the problem, the original ball with the taper was much stronger at this crucial point, now weakened by the undersized bolt, in Pete's case it worked lose but I can see the bolt breaking, due to there not being enough up/down movement in the joint itself, the reducer washers on Pete's had signs of wear because at full droop etc the arm fouled the reduced part of the washer, this imparts a bending moment on the bolt, not good, On Alex's truck I put those in the lathe and reduced the diameter to the minimum but still fouled on droop, just my humble opinion, I know they have been used for years on race/rally cars without problem but on a 4 X 4 with high articulation and all that off road throws at it I would not fit them to my truck, Rick
