I just had a ranch hand grille guard installed on my 03 Tahoe Z71. I wanted to see how much it lowered the front end, but I completely forgot to measure the clearance prior to installation. The suspension is completely stock, and I'm pretty sure the shocks are factory as well. I'm curious if anyone out there knows about how much it probably lowered my front end, and if I need to do anything to correct the change. The grille guard is a standard legend series from RH, which according to them weighs 121 lbs. I would assume that's not enough to cause any problems, but I figured I would reference the experts . Thanks in advance.
