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.


Hub Face and Spring Center Measurements on Standard Trailer Axle

Another helpful measurement to have is the flange-to-flange (C) length, which is measured from the outside of one brake flange to the outside of the one opposite. This length may be easy to obtain if you are replacing an axle, but it's important to note that this measurement is not the preferred method for determining which axle will best fit your trailer.


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.


Dexters

Dexters 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.

Great replacement axel for my home built trailer! Very knowledgeable sales staff, great help.



by:

Unbelievable how much a different changing to this axle has made with my 12 utility trailer. Rolls better than when it was new. Great product from a great company to do business with.



by:

The axle did not quit line up with the leaf spring had to use a come along to pull the spring together to get them to line up



by:

It fit right in no issue



by:

It was a perfect replacement for my trailer. The axle bolted right up to my springs and the brakes even bolted up without problems.



by:

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.

Good product. Installed easily and fit perfect. I was amazed how fast the axle was delivered. Made it easy to get my trailer back on the road.

How sweet it is



by:

Axles are great. The perches were welded 3/4 inch to narrow than what I ordered.



by:

Super easy to swap out with the old axle, the bearings fit the spindles perfect. The spring perches and the axle itself were straight, would and will purchase from again!



by:

excellent as always



by:

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.



by:

Great service! Axle was a perfect fit! Best store for trailer parts. I'm looking for fenders now. Guess where I'm going to buy them. That's right, right here. I suggest everyone do the same and save yourself the headaches of other stores backorder and bad customer service!



by:

Great axle. Very pleased with it. I was shipped the wrong axle butt etrailer sent the correct one and I was able to ship the wrong one back later. Got me on the road a little quicker.
Other than that mishap,Ian pleased with the axle and would consider buying from etrailer in the future.



by:

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.



by:

The axle I ordered worked great and after it was installed pulls even better than the one that was previously installed. Thanks to etrailer my old trailer is back on the road and the price was great. Thanks Again



by:

Appreciate all the personal service and being able to talk to technical help.



by:

The products are first quality manufacturers and service after the sale is always very good. The staff is interested and considerate when helping to solve any technical or installation issues.
They will also work with integrity to help you choose the correct equipment application for your needs instead of trying to sell you something that you don't need.
I have recommended etrailer.com to several of my friends.



by:

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. My order came way before the estimated delivery date, which is great for all the DIY’ers. The only complaint/suggestion that I have is to put the torque specs with the u-bolt kits. Over all the product is great.



by:

I have no problem with etrailer great service fast shipping Great communication but the dexter axle I purchased had poor weld job on one side dexter needs better Final assembly inspection practices Again I have no problem with etrailer

Fast delivery & well packaged. Great customer service!

  • Replacement 3500-lb Trailer Axle for 2007 Spree by KZ Tandem Trailer
    If your KZ Spree trailer's 3500-lb-rated axles are bent from damage or from overloading them beyond their weight capacity then they should be replaced. This will not only restore the trailer's handling but it will also prevent continued issues with uneven tire wear. Usually an axle that was bent from being overloaded will result in more wear on the inside edges of the tires. A new axle has a light upward bend that levels out under load.

    If only the axle is bent then you can go with just a new axle and reuse all of the other components like the hubs, bearings, brake assemblies, etc. To pick out the correct replacement axle you will need to get the hub face to hub face dimension of your axle as well as the spring seat center to spring seat center and the axle weight capacity.

    Yes, you can replace the axle on your trailer with one that is rated higher. This will ensure that the axle is rated for more than enough weight.

  • Can Wires on Replacement Axle be Used for Electric Brakes
    The brown wires on the axle # T3584F-8974 can be used to cross your electric brake power from one side to the other. You'll need to get power and ground from the trailer's 7-way to one brake assembly and then splice in the brown wires on the axle, one to power and one to ground. Then connect each of the wires to the brake on the other side of the axle. The brown wires can also be used for brake lights instead of the brakes themselves in the same fashion but not both.
