Well, maybe not sure. I looked in my logbook and did not see anything, however I posted in 2015 how K750428 was a heavy duty replacement for the K750012 so must have been thinking something then. I had added the TTR? Poly motor mount and rear sway bar sometime before then so who knows?
BTW, just bought new K750012 links from Rockauto, and one looks right and one looks to be a K750428 which is the 2009 and up part number listed. I will say the grease seal on the K750428 is cheap and not very well sealed compared to the K750012 and

has a different thread pitch.

 

Install those K750012’s and enjoy the ride!
