I would contact RC and get them from there probably.

 

Good call honestly. I just called them because I wanted to also see if I could add the little plastic dust cover to my order, which they did! I also asked if the ball joint itself changed when they changed the design and he told me it did not. So I assume I should be able to buy the same boots that OP linked in his post. I may just do that and if I fail to replace the boot, at least I have a new ball joint I can put in...again.

 

UPDATE: The replacement boots worked GREAT. So far so good, but the coming months will of course tell.

For anyone wondering, I called Moog and asked for the dimensions on their boot, the one that most closely resembles the part number that Rough Country uses. Below are the dimensions that I was given. I also have determined that Rough Country must be using some Chinese ball joints or something cheaper because I cannot seem to find the part anywhere online. In any case, enjoy.

small end: .698 - 17.72mm
inside big end: 1.506 - 38.25mm
1 1/8th tall - 28.575mm

 

You got a link for a replacement boots or ball joints itself other than the garbage rough country one?

 

Just a FYI...

I believe they use Moog K6540 for the replacement if you need to replace the complete balljoint. It's not a great boot design since it's pretty easy to tear them when installing.

 

Is the k6540 for sure the replacement for the rc uca’s? I’m trying to find a replacement other than the rough country one because the boots is so cheaply made
