I had not thought of the DOT issue. To solve this problem I can always leave the original seatbelts for streat use and the harness for offroading. Although it will not likely see any extreme trails as far as rock crawling it will have to be a very capable truck.
33s were my first thoughts but the more I research the more I am leaning towards 35s. What gears would I have to use to get back to stock or better?What is the going rate on average for the gears and labor for the swap? Del
