IMHO...
On a low/lowered truck, fast steering ratio gearbox and heavy sway bars make it more fun to drive.
On a lifted truck, I would expect the opposite. On my Suburban, w/ standard suspension but 10% taller than stock tires, I get tossed side-to-side more than I like when on rough terrain.
A "too big" sway bar in back can lead to oversteer, which in a PU with its light a$$ end might make it prone to easy oversteer and a wild ride. The Tahoe/Suburban utilities have much more weight in the rear to tame that behavior.
How big a sway bar is "too big"? I can't help you there. @Supercharged111 might have a comment.
If you want a Suburban sway bar, get the entire axle from a C1500 model and look for one with the 11" drums (I think they came on all Suburbans, but check first; they did NOT come on all Tahoes) ; the 11' drums would be an upgrade on your truck if you have the 10" drums now.
If you've 5-bolt hubs on your '92 C1500, shop accordingly.

Unless you are talking about a very light sway bar, I don't think the rear end of a pickup has the weight to push down on one end of the sway bay and will instead result in lifting a rear tire.
That's not how sway bar works. Body roll is countered by compression resistance on the outside turn , and extension resistance on inside of turn.
Suburbans have high center of gravity therefore anything that controls body roll is beneficial.
These vehicles aren't creating 1 plus g forces in cornering to lift an inside rear tire.
If it does, your already exceeded the center of gravity window and will have the front wheel tuck under resulting in forward rolling crash impact. Number of rolls will vary with speed and type ground surface. And we'll either see you in papers or ewe tube.

Yes, on Way Cool Jr, my '89 C1500.
Pros - Easy and it works
Cons - Requires welding
Get the whole sway bar assembly.

Bolt it on to test fit. If I remember right, you'll need to drill a couple of holes and install some grade 8 hardware. Lengthen the end links so that the bar is level at rest.

Use exhaust clamps to hold the sway bar to the rear axle.

Yes as far as I know all C/K1500 Burbs had the 11 5/32" brakes. Big finned drums, obviously different than the 10" ones (if the yard has pickups and SUVs you should be able to find both styles and note the differences). Entire axle is the best way to swap, then you get the brackets that are mounted to the axle tubes AND better brakes! You'll still need the front of bar brackets located on the frame, or fabricate something similar. Take lots of pictures from multiple angles for reference on reinstallation.IMHO...

@sewlow had an article about swapping the SUV rear bar into a pickup, by fabbing brackets, but it was some years ago. Maybe a search will turn it up....
