Sorry, I cannot see the good looks of a lowered vehicle. Stock height and stock truck in great shape, low mileage and no rust and then you got my attention. A lowered or lifted vehicle, IMO, will always have quality/uncertainty issues. Can't count on the work quality, unless I do it or know the qualifications of who did the work. The quality of components as well. Give me stock and improve handling and brakes and a clean rust free look. That is value to me.
You just described my '05..... * Also, in my mind, when I see a 'not new' Tahoe / Yukon, and is all stock, and very clean looking, I see it as a well-kept truck,... not messed with. More valuable.

The Hellwig bars fit easily front & rear on my stock '05 Yukon XL... Are you saying, the bars don't fit as well if your truck is raised or lowered?

The control arms are all in the same place with drop knuckles so that has nothing to do with it. The biggest issue I had with all three of them I’ve installed were the bushing brackets not lining up with the holes and had to be bent to line up. New sway bar links were a bugger to get started as well but the one I reused them, it wasn’t an issue. None of that is a deal breaker.
I’m just saying that everything isn’t necessarily perfect whether it’s OEM or aftermarket. The Hellwig bars aren’t perfect but that’s ok but a little tire rub is an issue even though that sometimes happens at stock height too with non-factory tires. The Michelins are more squared than the Bridgestones and rub on many trucks but they’re a far superior tire, so again that’s worth it. I’m pretty sure the 22” Bridgestones don’t rub with my drop but they’re garbage tires, definitely not something I’d go back OEM with.

Yea... I noticed a little mark on the L/H frame- bushing bracket, from a "tap-tap".... Just a little massage to fit...
Just like home construction.... nothing is actually square.... You have to make it fit.

When I bought my 04 LT last year it already had Bilstein 5100's in the front and 4600's in the back. I dont know how old they are as the truck had several owners. The truck has a bounce but what I dislike the most is the side to side sway on the freeway and over bumps. Its pretty floaty and has a body roll.

The truck has new sway bar end links as well as new inner and outer tie rods and an alignment.

I am right on the brink of needing new tires

Will a new set of 5100's fix this problem? Are there other, smaller suspension parts that would fix the issue before going for new shocks? Thanks.
I replaced rear coils , dramatic improvent .
Still have an extended bounce on the front driver corner .
So I guess I’ll need a torsion bar replaced ( shit) .
When I first purchased the 03 tahoe , I replaced all corners with rough country . Was not happy . But apparently it was my springs . I may have blown the front because of the need to replace torsion bar .
Gonna try replacing with bilstein 5100 first .

Just got the shocks and installed them it sure did ride all whole lot better and it FIXED The SWAY after replacing the shocks
My Tahoe swayed rolled and bounced .
First thing I did was buy rough country.
Minor improvement. New sway bushings . Minor improved. I got those
Super bump stops . Loved the ride but hitting bumps was hard because the Tahoe was riding on the stops . So I got new rear coils . Good improvement but the front driver corner is still bouncing longer. So I bought the 5100 . I hope they settle this row boats ride

Here's your help opinion you are looking for.

That sway bar has very little to do with the spring jounce effect. It will have a lot to do with spring extension if it is unhooked, like some off roader's do. It is to control body sway and shocks help with that too. Those shocks absorb spring action and stop the jounce effect. I did not go back in this thread and look. You have not said whether your suspension is stock or not. Lifted? Lowered? You could have a bad new Rough Country shock.

The Hellwig sway bar kits are solid steel instead of the hollow tube design like the Eibach. I have ordered the new front and rear Hellwig kits at ebay, to be installed soon. They are kit #'s 7701 and 7702. $7701 is $365.51 and 7702 is $262.59 and I bought from seller "neverenoughauto".

Not saying the Eibach kits are not quality at all but I would prefer the solid steel bars instead of the hollow bars. I just installed new KYB shocks but I agree with @91RS, at least match the 5100's or install known age all new shocks. The shocks control front and rear spring bounce oscillations and to a point the sway from centerline but the sway bar kits really will stiffen up that sway. I am really looking forward to the different comparison when I get those Hellwig kits on.
How did the Helwig sway bars work out? My 2004 Tahoe LT 4X4 has the same problem.

The Hellwig bars have been on for close to 2.5 years. Never a problem and still feel as good as day 1. It continues to amaze me how much difference those bars make thru curves and corners. I could not be happier.

Good stuff. I finally fixed my rear bar. Wasn't parallel to the ground--it is now. Weird thing is i had to take the jamb nut out to get it where it needed to be.
Due to the mechanical "sway movement", be sure the fittings don't move. ( Check in a week )
Take a picture... It should look like mine..... Is your suspension height, modified?
( After looking at the photo of mine, there may not be anything that will 'turn'...... But the vertical link should be solid and not move independently, from the bushings?

Yeah, I'm lowered 3".
This is the jam nut I had to take out for the bar to be parallel to the ground. Yukon new rear shocks.jpg
If i didn't take it out i wouldn't have been able to get it as low as it needed to be.
