Looking for thicker OEM Sway-bars

I have upgraded swaybars on pretty much every vehicle I have owned, but am perplexed by the huge markup on the bars these days, their price increases over the years seem to have substantially outpaced inflation (though I have no doubt that Hellwig, Eibach, Belltech, Nolathane, etc bars would be great). I am hoping to find thicker OEM bars that I can purchase used instead. Currently, my front is 1-3/16" (30.2mm) and my rear is 1-1/8" (28.6mm).

From my online research, it looks like the biggest that came stock on any of our trucks is 1-5/16" (33.3mm) front and 1-3/16" (30.2mm) rear. Is this correct? And if so, does anyone have part numbers or models/years/RPO codes that might help me locate some of these thicker bars (or one that you want to sell)? Unfortunately the “wander around your local junkyard with a caliper” option is probably not feasible for me.

Thanks!

I can't help you on acquiring the specific sway bar that you are looking for, but I can tell you that if you decide to spend the money on a great set of sway bars that really enhance the stability/handling capabilities of these trucks, Hellwigs are the way to go.

@915_Tahoe works with GM parts, so there is a chance that he may be able to assist you.

My understanding, regarding GMT800-vintage, is that parts from 05-06 Z56-PPV Tahoes or Z60 Sielvierrados - possibly including their front torsion bars? -
would make for better handling upgrades to our comfywhumpfie suvs with almost no modifications.
Also been told by reliable sources that we can use Hummer H2 rear swaybar hardware, provided we are willing to do some welding.
