There have been a rash of broken Heim links on the 2013's with the stock sway bar. Now 2 broken links with my 2013 sway bars. 1 on an ST, 1 on an RT. This seems to be a 2013 problem and I suspect we may be looking at a quality control issue with the 2013 Spyder links.
My bars do, by design, put more stress on the links but the pre-2013's have had no issues.
I am working on a better Heim link but it won't be ready right away. RabTech has put together a steel fix that should work well.
The replacement links from BRP are about $15.00 each.
I highly recommend getting this link replaced. I have sent you a PM
I don't have a 2013, but was thinking. I believe I read that the links are the same on the 2013 as they are for prior years (2008 thru 2012), so maybe the problem is the new higher position of the shocks?
