I have a 2003 ranger with a 3.0 and the dealer has told me that my max towing capacity is only 4000 lbs. Is there any way of increasing this to 5000 lbs? I now that if i had the 4.0 engine I could tow that much.
I have class III hitch and the trailer does have good brakes but the question I ment to ask is there any way to leagaly increase the trucks gcvw it can tow 5000 lbs. I guess if I put a 4.0 engine in it should be ok?
I don't think you can "legally" change the GCVW. The factory sets this taking into consideration the factory: springs; brakes; suspension; hitch; etc. You can add many things which might improve towing capability, but it will not actually change the "factory" stated GCVW. I might be wrong, but this is my "perception". Good luck!
