I suggest upgrading the rear suspension with air bags, timbrens, or sumosprings. The suburban will certainly tow without them, but they will make it much more enjoyable.
just a question. Does this just help with absorbing bumps a little better? I don't think the springs need any help on the burb. My tongue weight is probably around 900-1000lbs loaded and the springs seem to be fine.
The springs on a 2500 Burb need no help. No need to replace them with any of those products. A half-ton? Maybe. But not a 3/4 ton. See how flat and level mine is sitting? Stock suspension, 1100-lb tongue, no WD hitch. Perhaps the previous poster needed it because his quadrasteer Burb has more unsprung weight on the rear.
Now, on the other hand, the right shock absorbers will make a big difference. I installed Bilstein 4600s on all 4 corners on my Burb and the difference was like night and day. Wonderful, controlled ride, no porpoising at all.
Did you see a big difference loaded or unloaded with the 4600s? I think all the 8.1's had the autoride right? IMO my autoride sucks.
