Sure its' riding too low. Not only monkeys handling and safety, but your headlights are probably not on the road either at night, and can be a problem for oncoming drivers.
Install a Firestone Ride Rite Kit on back, problem solved.
They work with stock shocks.
Such kits have the option of simply using Shrader Valves to fill, mount them wherever convenient, or one can go further with an additional and optional onboard 12v compressor kit and gauge at the dash.
One can use a T, so that one line-valve fills both bags, or separate, I did the latter, each shrader valve is at the hitch side plates for easy access.
A kit like this won't ruin your ride.
I have this on my own '97, works like a dream. Pump them up to a maximum of 100 lbs if needed, I commonly used 30-45 psi, I can throw up to 1000 lbs of cargo in the back, and 350lbs of hitch weight, you'd never know it was there. How do I know? I've done exactly this with two 1600 mile trips across country with cargo area maxxed out, and hauling a cargo trailer.
It adds good stability, and will not ruin your ride, loaded or running empty and not towing.
Add Leafs, or air shocks, you'll likely ****** your ride comfort.
Run 20-30lbs for day to day unloaded, and go ahead, try bouncing on the rear step bumper! Nothing! Rock solid! Don't care if you're a 250lb man, you will be impressed!
You'll be very pleased with the results, I was. Takes about 2 hours total installation, only a couple holes need to be drilled each side to mount the upper bracket to the frame rail, the rest is simply bolted-nutted together. Route the air lines, secure with zip ties, find a place to mount the shrader valves, job done. Easiest when yanking the rear tire on each side to install.
Instructions were concise, and easy to understand. Easy as pie for me, but I was also an Amtrak Mechanic for 30 years (1973-2003), I was changing out 24" dia firestone air bags on superliner 1's when they first came out with the german made trucks underneath, and amfleet cars that have them too for years.
I've had my ride rites on my Tahoe for about 17 years now, I installed them in july 2003, and no problems at all, ever. Maybe once every 6-8 months I treat the bags to a lavish dressing of something like Aerospace 303 protectant to feed the rubber and keep them looking pretty.
