What should the Rear Sway Bar height be set at?

06 Taco · Apr 23, 2026

I leveled my 15 Yukon Denali by lowering the rear with a Max Trac 2"lowering kit and a small adjustment of the Magniride sensing rods. I'm happy with the trucks stance and my 5' tall wife say's that it's easier to get into the Yukon.
The rear sway bar height is now about 1-1/4 lower at the sway bar links than at the axle.
Should I get adjustable rear sway bar links and level the the rear sway bar or does this not matter?

Sway bars work best when they are level. Hellwig makes adjustable rear sway bay links.

The kit should work with ur factory setup. Quality of rubber can be done but unless it's on the ground u should be fine.

I'm thinking that if I'm going to change the rear links I should up grade the rear sway bar to the Hellwig.
Interested in comments on the difference in handling between the Hellwig and the stock sway bars

I lowered my 18 Suburban Premier with Belltech 1019 kit, 2" in the front and 3" in the rear. I also installed Hellwig front and rear swaybars, they make a difference but it is still a 19' long, 6000lb truck with a solid rear axel.

The difference in handling is night and day. Sure, it is still a truck, but a truck with virtually zero body roll, and one that handles one heck of a lot better and is a more stable platform. On my test highway offramp, I gained up to 5mph on the curve before tire squeal, with almost no body roll. Pricey for sure, but the difference is real.

As per Hellwig’s installation, the rear bar should be level with the frame rail.
Hellwig’s rear bar has a ‘firmness’ option ( 3 holes )….. Just use the 1st firmest hole.
The improvement of sway is SO MUCH BETTER….. like a new truck… Your stock GM swaybar is JUNK…. It is a hollow tube, and very light in weight. The Hellwig is a solid chrome-molly solid bar, weighting about 40 lbs.

Thanks for your help guys. I think I'll make the Hellwig Sway bars one of my next projects

That is interesting. The rear of my 2011 Yukon Denali XL 6.2 with the towing package had no rear sway bar from the factory. I purchased it new. I bought a Helwig for the rear when I upgraded the stock front sway to Helwig. Made a noticeable difference in handling.

Just did the hellwig rear bar on my Belltech lowered 2018 this past weekend. Noticeable handling difference for sure, also squats less on hard launches. My sway bar, however, is not level with the frame rails yet. I installed the offset links when I lowered it a couple years ago. But since the hellwig came with threaded adjustable links, I used those. Even with them threaded all the way in, they're still too long. Might possible re-install the offset links.

There was a guy who posted a few years back that he leveled his sway bar by installing longer bolts and shims on the bushings. But you'd have to do some digging to find that post. I have not gone that route as of yet.
