Ok all, after I get the bed off my truck I'm gonna put an axle flip kit on. My question here is the manufacturer says I will not have to notch the frame.. I haven't put shackles or hangers on the suspension only this flip kit. What are your thoughts on this???? I'm thinking they told me this because they aren't gonna be riding in it. I'm not hauling anything in this truck, just a weekend cruiser at this point. Any thoughts appreciated....
