Question:

I am building a sailboat trailer using the existing cradle that it is sitting on now. The boat, and trailer should weigh 9500 lbs, I came across the question you answered previously about using a tandem set of # ASR5200S01, but you also stated that they would need to be professionally installed, why is that ? I am hopeful that your recommendation would be the same as your response listed below. Thanks

As far as professional installation goes it depends on how you install the Timbren axle-less system # ASR5200S01. There are three ways to install the Axle-Less suspension and the second method may require professional assistance.

The easiest method, which is recommended if you are replacing axles on your trailer, is to install a piece of 2-inch x 3-inch rectangular tubing (sold separately - available at most weld shops) through the integrated hole in the Axle-Less suspension. Then all you need to do is bolt the suspension to the side of the trailer's frame with three bolts (not included).

The second option for installation is to fabricate an inboard extension plate that attaches the trailer's frame to the Axle-Less suspension. If something does need to be custom fabricated then in the process it may as well also be professionally installed.

The third method of installation is to bolt the Axle-Less suspension's hanger to the trailer's frame and to an existing crossmember that is in the area where you want to install the suspension.

With both the second and third options you must use three bolts to attach the suspension to the side of the frame. And you also have to use two or three bolts to attach the suspension to the bottom of the frame extension, or crossmember. Both the second and third methods of installation will eliminate the need for a thru axle and provide the most clearance.

Timbren's Axle-Less suspension units should be installed directly across from one another. Before mounting the units, measure back from the coupler and mark the frame to make sure that the two distance measurements are within 1/8 inch of each other. Then you can drill holes through the frame and attach the hangers with Grade-5, half-inch bolts (not included).
