Question:
I have a trailstar boat trailer. With 73” hub face and 60” spring center. What axle do you recommend with hubs and springs.

Hello Mike,
We don't offer a thru-axle with that hub face and spring center dimension so I can't give a recommendation on that. What I can offer is an axle-less system that bolts onto the frame of your trailer and doesn't require a specific length of axle.
The right one depends on the GVWR of your trailer, as you need a system with a rating that surpasses that. So for example either the 3,500 lb Timbren Axle-Less Trailer Suspension w/ Idler Hubs # A35RS545 or 2,000 lb Timbren Axle-Less Trailer Suspension w/ Idler Hubs # A20RS545.
