Axle Dimensions

Hub Face and Spring Center Measurements on Standard Trailer Axle

There are multiple ways to measure the length of an axle beam, but the hub-face-to-hub-face and spring-center-to-spring-center lengths are the most accurate. Hub face (A) refers to the length of the axle measured from the base of one wheel stud to the base of the wheel stud on the opposite side of the axle (when hubs are mounted on the beam).


The spring center (B) is the approximate width of your trailer. It is measured from the center of the spring seat on one side of the axle to the center of the seat on the other. This axle beam comes with the spring seats welded on.


If you are replacing your trailer's axle, you should be able to figure out which type you need by determining your trailer's capacity, the bolt pattern of your wheels, the brake type and the aforementioned lengths.


Dexter Axles

Dexter axles are made of high-strength steel and come with spindles and spring seats welded on. The spring seats are attached to the underside of the axle so that the leaf springs (sold separately) can mount beneath the axle. The result of this underslung design is a trailer that rides a bit lower for quick and easy loading and unloading.


Each axle is manufactured to create a certain camber angle. This ensures that the angle of the wheels is correct for your towing needs. Because the primary concern when towing is maintaining controlled, in-line movement, each axle is made so that your trailer's tires will run along the pavement evenly, with contact across the width of the tread. The result is excellent straight-line acceleration for steady, in-line tracking. You might notice the bend near the center of the axle; this is what ensures the proper camber angle. Having the center ride a bit higher and the sides of the axle bent lower allows the axle to give just enough to compensate for the load.

Review from a similar Standard Axle Beam in Trailer Axles


The spring center spacing was 74" as advertised. However, the information page made it sound like using this for my 74.5" spring spacing would be no big deal. I did manage to get it to fit but I will be watching this closely. There should be a statement on all trailer axles that stresses the importance of proper spring center distance or explain what is all involved in changing the spring mounting seat location.

Review from a similar Standard Axle Beam in Trailer Axles


I was surprised at how easy this whole process was through etrailer. I was looking around locally for the same axle and found several of the same axle but all were around $200. I decided the next morning I would go get one locally, but then checked here and found axle a lot cheaper here. It was a Sunday night when I placed order and didn’t expect any response on my order till Monday but to my surprise about 1 hour later I got a email saying my order was processing and then a little while later another email saying was ready to ship, all on Sunday night. Order cane in the exact day they said it would. Will definitely be using etrailer for all my trailer items now. Easier than amazon. Thank you etrailer.

very nice .handled well. I didn't like the position of the mount box ... I thought it should be on both sides. For me, since I created a custom trailer for a dinghy. The mounts when installed properly, sat to low. So, it worked for on the reverse but that meant the cam was reverse.

I needed to replace a bent axle on my 16 ft dual axle utility trailer. The axle from etrailer.com was OEM and was a perfect fit. I've bought from etrailer.com before and will continue to do so. They offer great products at competitive price points with fast shipping and great customer service.

Thanks for the follow up.....just another example of etrailer.coms outstanding customer service. And, what a coincidence,......I was just on your website in the last couple of days looking at stuff for another trailer I plan to purchase in the next few weeks.BTW....I stand by my initial reviews....outstanding products, fair pricing, fast shipping, and outstanding customer service.

Both the axle and u-bolt kit installed on my trailer with no hassle at all. This is the first time I’ve order from etrailer.

  • Installing Dexter Trailer Axle T20BTR-7258 In Application Where Spring Seats Need to be Opposite
    Since you need the spring seat on the opposite side of the trailer axle part # T20BTR-7258 that you referenced you'd need to either have the spring seat that's on it removed and attached on the other side of it or have new ones like the part # TRSS175 welded to the opposite side. The bow in the axle allows it to flatten out once the weight of the trailer is put on it. This is why you can't just flip the axle over.

  • Replacing Dexter 2K Trailer Axle with 70" Hub Length and 58-1/2" Spring Seat Length
    The Dexter 2,000 Pound Axle # T20BTR-7258 that you referenced is the closest standard axle beam option we have available to the specs you listed for your existing/old unit and it should work well as a replacement. The slightly longer 72" hub face length is just going to push the hubs a bit further out (1" on each side), which won't affect anything with regards to function but just something you should be aware of. It would also allow you to get wider tires down the road if you ever wanted...

    A 2,000 lb trailer axle like the Dexter Trailer Axle Beam part # T20BTR-7258 is not going to come equipped from the manufacturer with a brake mounting flange because of the weight of the trailer it is designed to be used on. However, most qualified welders can add the brake mounting flange part # 4-34 for a very small fee. The Dexter Trailer Axle has a 2,000 lb weight capacity, 58" spring center, and 72" hub face length. It uses a L44649 bearing on both the inner and outer seats. Once...

If you have a trailer that has the springs centered at 58 inches on center and is 1-1/2 inches square, then the axle is a 2,000 lb axle and you would use the Dexter Trailer Axle Beam with Standard Spindles - 72" Long - 2,000 lbs # T20BTR-7258 with hardware # APUBR-10.

  • Replacement Axle for 2,000 Pound Dexter Axle on a Pop-Up Camper
    We have straight axles that are close to the measurements you have provided, see link, but the spring seats would have to be moved and none of them have brake mounting flanges. I propose a different approach by using a Timbren axle-less system # ASR2KHDS01.

  • Can I Relocate The Spring Seats On Axle To Where Spring Leafs Are Located To Widen Trailer
    When positioning a 2000 pound trailer axle like # T20BTR-7258, it is recommended that the hub face to spring seat measurement falls between 5.75" to 7.625" on each side. (11.50" to 15.25" total on both sides). (see picture). As long as your axle is within those parameters you will still be able to utilize all 2000lbs weight capacity of the axle. If you go beyond those measurements you could jeopardize the integrity of the axle.

  • 72 inch Trailer Axle with 2k Capacity and Hub/Drums to Match
    We have 72 inch axles that are 2k rated with idler hubs as a single part number but none that have the hub/drums on them so you'd need to order an axle with spindles only in that configuration and then add the hub/drums and assemblies like with the # T20BTR-7258 and then hub/drums # 8-257-5UC3 and then for assemblies # 23-47 and # 23-48. Then for a wheel and tire that's 15 inch with the bolt pattern you are needing the part # AM32418DX would be a great option.

Most axles that are 72 inches from hub face to hub face are only rated for 2,000 lbs like the Dexter Axle Beam # T20BTR-7258 so this hub assembly would be a great option.

  • Reducing Overall Trailer Weight By Replacing Beam Axle with Timbren Axle-Less Suspension
    A standard beam axle made for a leaf spring suspension will vary only slightly more in its actual weight, depending on its carrying capacity, than two Timbren axle-less systems of different capacities. This is because as weight ratings increase a beam axle tends to have a larger diameter and more steel, which makes it heavier. With Timbren kits there will be a bit less of a weight difference. For instance, Timbren 3500-lb-rated kit # ASR35HDS02 has a shipping weight of 152-lbs, while...
