I have put 1.25 spacers on, they are not spidertrax but exactly the same and not anodized, because the would have cost me over 400$ here in quebec, canada. so in my book, the spacers only keep you from rubbing the sway bar. but they add more problems than solved problems. I think it all depends on what tires you put, I have put 245-75-16 bfg AT and it is a really square tire. as you will see in those pics, they dont rub anymore on the swaybar but now on the pinchweld, on the flare in front of tire and on liner, but the look is IMO much more better, see the first pic the tire is mounted without spacer and dont rub anywhere exept SB and then with it. the difference is really noticeable.
I bought them first to get the look I want my jeep to have(love jeep with tires passing the flare(miss my rubicon)) and then for stability and keeping it from rubbing the sway bar.
it's not much of some littles problems to fix. now it run just fine and dont rub anymore.
check the pics.
