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.
etrailer 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.
This hub-and-drum assembly meets the requirements for certification by the Canadian Standards Association (CSA). The CSA creates standards, which when complied with ensure a safe and quality product. This assembly underwent extensive testing to measure stopping distances when braking. This assembly has also been tested by QAI Laboratories for braking performance in a complete automotive setup and under real-world conditions to provide the most realistic scenario for the everyday driver.
The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.
On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: 8 on 6-1/2 means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)
To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: 5 on 4-1/2 means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)
Measuring the distance (D) from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

In order to find the correct replacement axle for your trailer there's a few things you need to do. The first one is we need to determine the capacity. The first place I always check for the axle capacity is on the axle tag, which is actually located on the axle. Now, most of these are in the center and they could be a white sticker or they could be a metal plate. Now, not all of them list the axle capacity, but the vast majority do, that's why I look here first. Granted, this is a new axle here, so the tag is in fairly good condition, but we can see on here GAWR, gross axle weight rating, 3,500 pounds, so I know this is a 3,500 pound axle.
So if you do have an axle tag and there isn't a capacity listed on there there may be a serial number, an axle number. And in which case, you could actually reach out to the actual manufacturer with this information and they should be able to give you the capacity. Some of the more common axle manufacturers on the market are Dexter and Lippert. So if you don't have an axle tag, that's okay. There is still other options to determine the capacity.
One would be to take a fabric tape measure and record the circumference of your axle tube. Now, once we have the circumference we can use the appropriate formula to get the diameter. And then using the diameter there's sort of a general axle guideline to determine capacity based on that diameter. So, for example, a 3,500 pound axle is gonna have a 2 3/8 inch diameter beam. Now, a 3 inch diameter beam would represent anywhere from a 5,200 pound to a 7,000 pound axle.
And there's also some larger ones as well as some smaller ones. So if we don't have that axle tag there we could just measure the diameter here of our axle tube. And another way is to actually look at the brake mounting flange bolts. Now, this is just gonna give you a rough ballpark. The 3,500 pound assemblies, they usually use this 4 bolt pattern where it's the larger 5200 to 7,000 pounds, use that 5 bolt pattern.
So that's more of a general guideline. That's certainly not all you wanna do, but it will help you reaffirm when you're measuring. So once we get to capacity there's two more things that we need to gather. The next one is going to be the hub face length. So the hub face length is gonna take our brake hubs into consideration. We're gonna be measuring from the part of the brake hub where our wheel mounts from one side to the other. So we'll go ahead and do that now. Now, once we have our hub face length, we need to determine our spring center length. So the spring center length is gonna be from the center of the leaf spring perch from one side to the other. So once we have all this information we can then use that to select the correct replacement axle for our trailer. We have a ton of different options to choose from based on a few different factors. Number one is the length of our axle, both the hub face and the spring center. There's gonna be several different options for each of these. There's also gonna be different axle capacities based on how heavy you need your trailer axle to be and how heavy your trailer is. Now, we always recommend replacing what's on your trailer with the exact same one that came off. So, for example, if your old axle had an 89 inch hub face that's what we'd recommend replacing it with. And the same goes for the weight capacity, although you can upgrade. No matter what capacity you need we should still have an option for you. Now, in addition to the capacity, we're also gonna have axles with a built-in drop if you need that, or just a straight axle. And we also have some different kits that are gonna come with some different components. We can either purchase the axle, just the spindle only axle. We could get this with an idler hub, or we could get this with an electric brake drum and some electric brakes, depending on what capacity you need..

Easy ordering, axle arrived on time and no damage. The axle worked perfect for my camping trailer, would recommend your company any time.
I'm currently installing it to replace a practically good Axle but the Spindle on the original Axle doesn't have Cotter Pins. A friend suggested I change the bearings since the wheel was wobbling but after I changed them, the wheel continued to come off. After watching U-Tube Videos, everyone of them had Cotter Pins, so I decided to be safe rather than sorry and replace the Axle with one of yours plus now ALL the bearings are NEW with New Hubs, WELL WORTH THE MONEY I SPENT.
I purchased two of these axles to replace my old square ones. They appear to be good quality but they arrived damaged. The grease fittings on the ends were smashed because packaging wasn't adequate. I've emailed back and forth and was shipped the wrong parts for replacement. In the end I was told I'd have to cut the spindles off and replace them. All I need is new grease zerks that thread on the ends of the axles. Be prepared to purchase these on your own because customer service is subpar on a remedy and the way they package them for shipping does not prevent damage.
Needed to beef up my little trailer project from a 4 lug to a 5 lug st up.These were perfect, and arrived quickly!
Axle and hubs were good quality. Dimensions were spot on 48" center hole of perch to center hole of perch. But.......some knucklehead built my trailer with 47" centers - so I ground off the perches and relocated on 47" centers. Took just over an hour to cut, measure, grind and weld old perches on new centers.
There was one odd phenomenon I've not seen before. The cotter pin hole was not driven through the center axis of the axle but rather offset to one side. Maybe that's how things are made these days.....or someone sneezed at the factory and the cotter pin holes moved. Nonetheless it's installed and works.
My Etrailer salesman, James X-72990 was pleasant in taking my order but told me the axle wouldn't be here for over a week. Then - he must have done something and the axle showed up in 2 days.....(Thanks James) Good product, good experience.

The axle is of great quality, I had to have mine fabricated a bit to match the old spring seats.but I wouldn't hesitate to buy the axle. The shipping and customer service is top notch from etrailer. Excellent products, services and shipping...
Just what I ordered, had to modify to fit my 1720lb Harbor Freight trailer as far as the spring seats. I knew that going in so no big deal. Great help and info from the order person.
Matched it up with bigger tires and etrailer finders!!!
Item was exactly as described. installed yesterday and everything fit perfect.
But one thing that did concern me was the way it was packaged for shipping. I think we clearly know how UPS handles items. Maybe boxing it up with foam inside would be ideal, but also understand the cost efficiency side of it. Just something to consider for future orders. overall thank you Etrailer for the item.
Easy to work with company. Very helpful in helping me to select the correct axle. The videos installation were helpful. I have been traveling around the country with the new actual on my small mini camper and it's worked out great.
axle is very rusty after one year as well as hubs, not sure why but price i paid it shouldnt be rusty
Axle came pretty quick and we'll packaged. Hubs came in separate boxes. Took out the old one and attempted to put in new one. The mount brackets on the new ones are a full inch apart farther than the original, therefore it doesn't fit. Not sure what to do.
The axle shipped on time, was a perfect match for what we were needing. I have ordered other products from etrailer and will continue to do so. Keep up the great work!
Had to modify trailer and axle has worked has it should.
excellent choice for the price. made a trailer from scratch and acle worked well
The original axle on my trailer suffered a catastrophic event, making it absolutely unusable. The replacement from etrailer fit like a glove and installed in a very reasonable amount of time. I couldn’t be happier.
Just what I was looking for. Speedy shi pping
The box carrying the axle was empty. You might want to protect the ends of the tube better so it doesn’t fall out during delivery.
Works great fast shipping nice people to deal with.
The axle and hub/bearings were great, very good quality.
Just fyi, regarding the u-bolt kit, 2 of the 4 u-bolts supplied were 3/8 UNC thread and the other 2 were UNF--- but all the nuts were UNF --- fortunately I had some spare UNC nuts on hand. Very pleased with the quality and speedy delivery.
Unwrapped, looks good not yet assembled
Fast delivery, well packaged, so the axle wouldn't get damaged during shipping! Would for sure order again, and highly recommend etrailer!
Axle was exactly what I needed. Have pulled it dozens of 500+ mile trips in the last year and doing great.
