Will do. My truck is a 4WD with 3" blocks under the rear springs, with the short 1/2 inch thick spring removed (for comfort) and Firestone lift bags on 30psi, and a 2" leveling kit which consisted of a fairly long 4 leaf spring pack added to each side at the front.

No vibrations down low, but I get some sort of harmonic resonance at about 80kph which I suspect might be the rear tail shaft/s slightly out of balance. Not a huge issue as the noise is gone by 90kmh, but annoying enough in the 80 kph zones...
