When replacing regular axles with a Timbren Axle-Less system, you will absolutely want the Timbren axles to go in the same place as the existing axles. Axle placement is critical to the weight distribution and ride quality of the trailer. Trailers are designed around a specific axle placement. Moving the axles farther forward or backward can lead to issues with sway and/or ride quality.

Also, a lot of times the tires will need to fit inside the existing fender area or wheel well, so there is no room to move axles forward or backward anyways. Another reason to keep the axles in the same place.

For a 3,500 lb Timbren axle we have the # A35RS545 which comes with 5 on 4-1/2" idler hubs. Or if you want electric brakes, we have the # A35RS545E which comes complete with electric brakes and hub/drum assemblies. This also uses the 5 on 4-1/2" bolt pattern which is standard. There are also rise and drop axles available if you would like to raise or lower the ride height.

The link below will show you our complete selection of 3,500 lb Timbren Axles so you can see all of the options. I have also linked a video showing a Timbren axle being installed on a single axle trailer.
