I'm lifting my work vechile because i keep bottoming out on my way to houses. I dont know how much weight i carry on regular basis. I do know that when I'm all loaded up for the day I look like i've lowered the rear to match the front. My question would be if i did the bds lift and z71 rear springs would that give more payload. I think probably right at load capacity if not just over. I also do some mild off-roading for work (driving up some really washed out driveways).
