There really isnt much of a difference from stock height to a 3/4 drop. Still plenty of travel in the suspension (one of the reasons I love our trucks) and looks 1 million times better at a lower height. I say go for it, Los Angeles has some of the worst roads and freeways anywhere and I love my drop and wouldnt even think of raising it back up.
yeah, s10rz350 makes a good point, for awhile when i first got my truck i drove around with a 4 inch drop up front (2 inch coils/spindles) and a 3 inch block in the rear, i never had any problems related to bottoming out or anything, i was on those humongus stock tires as well. so im always for the drop hehe, by the way s10rz350...... is that your name cause you also own an rz350??
