I've been wanting to get some 33s on my 2nd gen when it's time to replace the 31's that are on it and looking at the OME suspension kits to accommodate that. My question is, how do I know if I need the medium or heavy kit and the one with/without the torsion bars? I am new to lifting trucks so I wanna know what I'm doing before I go in. Also, I've noticed many people re-gear their trucks when stepping up to the 33s. Is that recommended as well? If it gets too expensive I may just stick with the 31s cos I'm not a serious offroad guy but I would like to prep my truck for an overland trip in a few years. BTW, looking at the General Grabber A/Ts. How do we feel about those here? Any insight is appreciated.
