There isn't any way to increase the current axle capacities. You would need to simply replace the axles to increase the weight capacity. You simply need to find your hub face to hub face dimension and the spring center to center dimensions if using a through axle. Your other option if you can't get the correct fit is to use the Timbren Axle-Less Trailer Suspension System w Electric Brake Hubs like # A35RS545E which are a universal fit. They mount to your trailer frame directly and have the integrated suspension. Then you simply run a 2 inch square bar (not included) between the assemblies to give you the stability needed. I've attached a couple videos to assist.

I've also linked the page to all your axle options to assist. If you replace the axle with a through axle you will also need to update your spring suspension. Your trailer will be limited by the weight capacity of the weakest component whether the axle, springs, coupler, wheels, tires, or frame.
