Wow...Your first post. /forums/images/graemlins/thumb.gif Welcome to ColoradoK5. /forums/images/graemlins/smile.gif
As for your truck....It could be many things. Did you get it aligned after the lift? It could be brakes worn out, caliper sticking, wheelbearings, one tire with low pressure. If it pulls while normal driving and while braking..I would think it would be alignment related. After ya drive for ahile, get out and feel the front brakes, grab the hub, see if one is hotter than the other. If one is hotter, then a caliper is sticking. A front brake job is fairly easy and inexpensive. Might be something worth looking into. /forums/images/graemlins/thumb.gif
