Hi Ron,
Re: If it fails it may well fail when you need it most.
OK, this is for you. When I bought my swaybar from you earlier this year ( '08 SE5 ) I asked about the metal links. And you said that I did not need them.
Have you changed your mind?
I'm not arguing, just wondering.

No argument taken. These are important questions and I hope this forum is the place to come for honest answers.
I have been in the process of changing my mind. I never want to push something onto customers that I feel is optional. The question is, are the links really optional?
In all of our testing we only had failures with the problematic 2013 recalled links. This was understandable since they were also failing at a high rate with the stock sway bar.
So I did a stress test on some good OEM plastic links to get a better idea of how much stress they can take. They stood up to loads beyond what my stiffest sway bar would exert. But though the plastic links did not fail this test, they did stretch. Of course they returned to their original length when the stress was revealed. But it left me wondering what the long term effects might be.
The second unanswered question is; How much variance is there in strength from one link to the next? Because some OEM links have broken with stock sway bars while most OEM links hold up well even with my stiffer bar installed.
The issue is, you don't know if your OEM links will hold up until you try them. If they break, then you know you should have replaced them. This is not a good way to find out and I know of no way to inspect the OEM links tol improve the situation.
If you have a 2008-2012 GS/RS/RSS bar, it is the least likely to be a problem for the OEM links. All the other bar kits put more stress on the links with the 2013/14 RT bar being the stiffest. That is why I now require that the 2013/14 bars be installed with my Billet Aluminum links. I don't want any link failures so I may expand this requirement to other bar sets.
At this point I am highly recommending my links. I want my products to be problem free and certainly failure free. Some have installed my link set with their stock OEM sway bar to avoid breakage.
