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.
My Burb has the AutoRide option, so you have to stay OEM or an aftermarket direct replacement to maintain the active suspension.
