By any chance do you have any noise coming from your rear sway bar going over bumps? I get an annoying clicking noise from the rear and can only see it being the sway bar. With the aftermarket links the bolt doesn't fit snug enough and moves around up and down causing the noise I think. My sisters 03 Tahoe with a rough country 6" does the same thing.
I tried seeing where you found that part #FTS1126. You have a 2001 Tahoe 4wd or 2wd with autoride? It really shouldnt matter for front.... however the part# you found is a "Bushing replacement KIT" so that should be all 8 bushings. Best thing is to call 4wheelparts or fabtech directly and verify the quanity in kit and part #'s. You wont have to spend $200. Thats way to much!
I bought front sway bar links awhile back. And it came with both links, hardware and bushings. If i remeber correctly it was around $60-$70 from 4 wheel parts.
Then I replaced the rear bushings only. That was around $32 just for just the bushings.
Give them a call. they will set you up correctly.
As far as the hardware for the rear sway bar links. Fabtech says replace bottom bolts with a 10.9 grade or grade 8 bolt. Use factory bolts for top of rear sway bar links.
