I have been looking in to building a ride truck over the last couple of months. My questions are, can I run 2.5 ton axles or would the 5 tons be better, and can I run the stock frame on the truck and add the 4link brackets to it? I got some steel 2?x5?x1/4? for the frame, as I was looking at some of the ride trucks they look to have the stock frames. With shock and 4link brackets welded on. Any information would be helpful.
