Replacement Drop Axle for Old Horse Trailer with 6 on 5-1/2 Inch Bolt Pattern

Question:

I have an old horse trailer that needs a new hub, bearings, seal kit but not able to match the dimensions. Hoping you have something that will work. The bolt pattern needs to be 6 on 5.5.

I would love to help but we do not have any trailer hubs that correspond to the dimensions that you provided. Therefore, the only option we can offer you would be to replace the axle all together. In order to offer a replacement for this we would need to know your spring center and hub face measurements (see photo). If you can provide me with these I can then see if we have an axle suitable for your trailer.

For example, the Dexter Trailer Axle Beam with 4" Drop E-Z Lube Spindle part # 7685269 has a 3,500 lb capacity with an 80" spring center and 95" hub face measurement. It can then be used with the Dexter Trailer Idler Hub Assembly part # 84655UC1-EZ.

Question:

Thanks Connor. The current axle has no spring pads attached, its simply a 1.75" square axle with 4" drop that's bolted to the springs with u-bolts I think you can see in the picture. The distance between the spring centers is 55". The distance between the two hub faces is about 79 3/8" the best I could measure. The distance between the back of the 90 degree uprights on the axle is 61 7/8". Please let me know if these measurements will allow you to specify an axle that will work.

The spring center and hub face measurements you provided are not synonymous with the bolt pattern that you need therefore your best option would be to look into the Timbren Axle-Less Trailer Suspension System which will actually replace the leaf springs, axle beam, and hangers/equalizers with a set of rubber aeon springs that will work to provide a smoother ride in addition to better supporting the trailers load.

In order to recommend a set for you I would need to know your axle capacity. If you have 3,500 lb axles then you can use the Timbren Axle-Less Trailer Suspension System part # ASR3500S04 with the Trailer Idler Hub Assembly part # AKIHUB-655-35-EZ-K. If you have 5,200 lb axles then you can use the Timbren Axle-Less Trailer Suspension System part # ASR5200S04 with the Dexter Trailer Idler Hub Assembly part # 8-213-5UC1-EZ.
