air shocks

What air shocks are best to install for towing? I have a 2000 astro

I replaced the old worn shocks with Monroe Sensi-tracs.
They're better than new OEM shocks (for ride and handling), and work fine with my approx 3000 lb trailer.
I don't know about air shocks, but since no-one else wrote, and thought I would

Best to stay away from air shocks. Reason: Air shocks can, will, and do change the front to rear attitude of the vehicle which in turn drastically affects front wheel camber, which in turn affects toe in, (the two most critical front end alignment angles that cause excessive tire wear). Best to stay with a good brand of heavy duty shocks, and/or, if necessary to keep the vehicle level while towing, have a reputable spring shop add a leaf to the rear springs, then have a front end alignment performed. The sole purpose of a shock absorber is to dampen the action of the springs, NOT to raise or lower, that is the job of the springs.
