Not sure if this belongs here or in modified tech, so here goes. I just ordered a new pair of sliders from VKS fab that are frame mounted and can be either drilled or welded. After talking to Vick at VKS I decided to weld because I was under the impression that it would provide better overall strength. Then I talked to a guy at work who said that welding to the frame of your vehicle is stupid because it is a hardened steel and there is a greater possibility of the frame cracking in that area once it has been welded. My question is does that statement have any merit or is that a bunch of BS?
