anti-sway bars

I have a '02 4wd Yukon that seems way to mushy on the curves, ie excessive body roll, especially in back. Does anyone know the stock diameters for the front and rear sway bars? Has anyone replaced them, and if so, with what size and with what kind of results. I do not want to lower or raise the vehicle ride height, just cut down on the body roll.

Aftermarket anti-sway bars are a great mod. I've run two different sets on my trucks - Hotchkis and Eibach. The Eibach bars are ~ $100 cheaper and are painted bright red, if that matters. I've been really happy with both.

You'll notice an improvement in handling, but it won't be night vs. day. I did see dramatic handling gains when I dropped my truck, but I certainly appreciate that this isn't an option for you.

If you have the chops to install the bars yourself, the Eibach kit goes for a little over $250. Alternatively, you can guesstimate 1.5 - 2.0 hours of labor for a shop to perform the work. Good luck!

I'm a DIY'er to the end and also tight with my money! Do you know what the Eibach diameter was? Are they solid or hollow? Was there a performance difference between the Hotchkis and the Eibach? Were they different diameters? Did you do front and rear? Do the kits come front and rear or separately?

Thanks!
