I have a '93 Suburban 1500 that I would like to add a little lift. There are several options available. Does anyone have experience or an opinion on the 1"-3" lifts by using a new torsion key for the front and a block for the rear? This method seems more DIY friendly. I am also thinking I would need to add new shocks (longer). I'm not really fond of the lifting blocks, add-a-leaf would be cleaner. Your opinions would be appreciated.
