I'm wanting to install a 4" lift kit on my 77 k10. My question is this. I don't want any supprises when I'm done. I have herd of people getting vibrations and swaying. Other than what comes in the kit is there any additional equipment I need to use. Like sway bar drop kits, transfer case drop kits or longer drive line. I was thinking of using thr rough country kit. I want to do it right. Any suggestions would be great. Thanks
