I am thinking of doing the rear shackle flip that I have seen alot of you guys do. I just have a few questions. . Is it a better ride than new springs? What all is needed? I saw the kit from DIY4X, then i have to buy shackles too right? Or does that kit come with everything? Is it hard to install? I don't know alot about suspension and how it works. . Is there a detailed write up anywhere? What tools are needed? Any welding or anything? Anything else I should know before attempting this?
