I can tell you where the spindle of the Timbren Axle-Less Suspension System, # ASR3500S05, will sit in relation to the trailer frame, but I do not know how that will compare to your current setup. Once the Timbren system is installed, the center of the spindle will sit 4 inches below the bottom of the trailer frame (see photo). This system will have 1-3/4 inches of deflection when fully loaded, so under a full load the center of the spindle will sit 2-1/4 inches below the bottom of the frame rail.

To compare this to your trailer, measure from the center of your axle tube to the under side of your trailer frame.

The system uses a number 84 spindle that requires a L68149 inner bearing and a L44649 outer bearing with a 10-19 grease seal. I you are planning on using your existing hubs, I recommend comparing your bearing and grease seals to these numbers to make sure they are compatible. If you want new hubs, you can use part # 84545UC1-EZ.
