Trailer Frame Mounting Space Required for Installing Timbren Axle-Less Suspension System ASR5200S04

Question:

can I mount this axle directly to 2x3 x 3/16 trailer frame member... bolt or weld or should I fab a mounting..? Do you have a PDF of axle mounting area.... trailer has 18 deck and will haul 3000# car typically.

The Timbren Axle-Less Trailer Suspension System # ASR5200S04 that you referenced will require a trailer frame area of at least 14-5/16" inches long and about 3" tall for proper mounting. I have attached a dimensional diagram below with this and other measurements labeled for the setup (just note that the spindle measurement isn't correct since this model features a 4" drop). When mounting to the frame it's extremely important to use all 3 bolt holes provided, so this full length is needed.

It sounds like the area you have picked out on the trailer is a bit too small, unless I'm not understanding correctly. If you can send me a picture of what space you are referring to on the trailer or give me a little more detail on what yo have in mind I will be happy to help you further.

I have attached an install video as well that you can use for reference.
