hey im going to be ordering a 6 inch lift kit soon from rough country since i need a stronger spring rate for hauling. now im racking my brain between 4 inch heavy duty or a 6 inch. the reason im racking my brain is cause im worried about inspection laws i got a few of my friends that works at inspection garages but they all tells me different story. emission is covered for my truck.. but im worried about the lift kit.. if its too high i cant get it inspected cause im going to use the truck on weekends on road and off roading too.. and for enjoyment too. so im curious what u pennsylvania guys know about inspection rules for lifted trucks.. how many inches from bumper to ground. etc. thanks for ur help.
