Can I just upgrade to 5200 pound axles ?
OK...example; I have a trailer frame with dual axles rated at 4400 each. The frame design is well built with a tubular frame. So lets say the axles are rated for 4400 each now and I have 15 inch E rat...

You can always upgrade axles to whatever you wish to install/fit on your trailer, Is it safe, maybe, does it increase your GVWR, probably not unless you have or know an engineer to determine the frame/hitch capacity of your trailer.
Without that, the only thing you can safely accomplish is to have an increased comfort zone knowing your tires and axles are plenty heavy enough and rated enough to haul your #8800. The same physical size frame from one trailer to another doesn't mean they are rated the same. Thickness of the tube wall or web, flange thickness and width of an I-beam flange also come into play to determine load rating. Just my opinion from working in the metal industry for 40 yrs.
