It's usually enough for a lot of situations. But if your in real deep stuff and need those wheels to spinning to keep you going pulling the fuse is probably needed. It's something you need to figure out for your self I don't play in mud so I don't know. I do spend a lot of time in deep soft sand but my tires grip like there on concrete so I've never needed even 4LO in the stuff where everyone else was getting stuck. LOL
