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 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.

Determining the Bolt Pattern

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.

Bolt Pattern - Even

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.)

Bolt Pattern - Odd

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.)

Bolt Pattern - Side

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.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

These axles work great. I replaced three axles on my trailer last fall (2022) with these axles. I was able to install the new axles and springs in about 3 hours because everything matched up very nicely - thanks to the help of the folks at etrailer.


I installed the Dexter axle on my trailer yesterday, and I was very impressed with the quality and the ease of installation. The install took much less time than expected, and this was helped by the hubs having the bearing pre-installed, what a bonus! This is a great solution to replace a fried axle, I highly recommend it.


Everyone at Etrailer are awesome to work with. Thank you all.


Great company. Never a problem with orders. Fast shipping. My first stop when I need something.


Highly impressed with the entire experience. From product selection to the almost immediate order prep and detailed shipping progress and tracking. It gives me hope for American companies. Great job keep it up!


I recieved it when promised and it looks to be a great product. Will be installing it soon.


I gave a 2 because my complete order was not delivered. I ordered a complete axle for my trailer, but only the hubs were shipped. I had to call and find out what happened and the representative said they didn’t know why it wasn’t shipped but she would make sure it would be completed.


Great customer service and great, name brand products!


everything fit great, you need to package the tube of grease better, the one end of the tube was smashed from the box being dropped on one corner. was unable to use the tube of grease, so went to our local NAPA store and got a tube.

That would be a messy situation! I know that you replaced the grease however I will still have our Customer Service team reach out to you on this.


This was an easy installation. Nicole, our service rep spent a long time by phone to help us get the perfect part for our trailer. She was a valuable asset to making our purchase great!


I changed the axle on my boat trailer a year ago after finding the spindles pitted and leaking grease from the rear seals. Purchased an axle from e-trailer with bearings seals and spindles and was very pleased. etrailer has been a company that I would do business again as needed. Their products have been shown to be a good quality and have arrived on time and in good condition. Have been very pleased with the experience.



Have had no problems with product. Worked out fine.


Purchased a trailer axle with hubs. I had lost a left wheel, hub and all and was lost at a loss as to how to proceed with fixing the bent, now damaged left spindle.
Finding the complete axle and hub set up at etrailer was a God sent.
The removal of the old and installation of the new axle was easy. Slide it in, tighten up the u-blots and you're home.
A side positive was that my new axle had a pre-load bend in it and also preset for toe in. Toe In like on your car to keep it running straight down the road. ( you'll have to read they're information literature)



We haul the trailer to Chicago often. The axle is still in service and giving us no concern for worry. In fact, the trailer tracks better than it ever did using your axle setup.


I removed and replaced my boat axle and springs including welding on the new hanger hardware before noon and was on the lake that afternoon. All the parts and pieces fit like a glove. Thanks Again Etrailer.


Axle is two inches longer than the original axle on a 1986 trailer but the tires still ended up neatly tucked under the fenders. It was shipped lightning fast, was easy enough to install and has worked flawlessly for just over 10,000 miles now. Excellent!


made very well, high quality just what i needed


Very satisfied


EZ Lube axle, why didn't I have this last year? With a slight modification (weld new spring seats) 2"wider track, new hubs and springs the pontoon was back to the lake the same day. Now I never have to worry about repacking bearings again. Thanks etrailer


Great service with knowledgeable staffs, on time delivery.
good quality and a fair price for complete axle, hubs assembly, although i received the axle, bearing hubs in good conditions the inner seals was damaged from the boxes being bounced around during shipping. Yes i would shop again at


Thank You etrailer for the quick service and delivery. This axle and idler hubs EZ lube was an easy install and exact fitment needed. 1 yr. in service and doing good.


Maria K. went above and beyond to get me my trailer parts. Shipping was fast and I am extremely impressed with the service I received. Thank you.


The axle I ordered was successfully installed yesterday. One issue I had was with the spring seats. My spring centers are 72 1/2. Knowing that I ordered the Spring Seats TRSS238. I cut off the seats that came with the axle as I knew I had to do but when I went to install the new seats I found the cutout diameter was too large for the axle.
For that reason I did not use the seats. Fortunately I did a neat job of cutting off the original seats so I welded those at the location I needed. They worked fine and fit very well. It would have been a problem if I did not get the seats off the axle as neat clean as I did.
Other that that issue the axle arrived in 5 days through standard shipping and hopefully will work for years to come.


Ordered an axle and 2 trailer tires mounted on wheels. Cost is very reasonable and items were delivered promptly. This was my first time using etrailer and I am very impressed with the service and quality of items ordered. Will be a repeat customer.


God the product in two days from the order day. It came in perfect shape and ordering the additional mounting brackets was very easy. Item is sturdy and was quite easy to install, especially using the helpful instruction video link (there is one missing step in the video, though. It does not show the mounting of the bushing that fits next to the inner bearing on the hub, but it was still pretty easy to figure out). Great purchase and the whole axle swap took less than 30 minutes!


The parts were well protected and boxed during shipping. The parts were as described on the site. The bearings all came from China which would not have been my first choice but hopefully will be suitable. I would recommend this seller.

Tony S.


The center to center distance was 1 different for my trailer. I cut the brackets off and rewelded the brackets in the new location. The axle has worked well and I have had no problem. As I use the trailer only a couple of times a year the bearings that came with the axle have been fine so far.


I ordered several items for a trailer I am rebuilding. One thing i ordered was an axle with hubs. When the axle arrived there were no hubs and I was worried. But when the second box arrived there were the hubs I was expecting. Thank you your pics and shipping saved me over $200 on a single axle.

  • Replacement 3500lb Axle for 1992 Classic Bass Boat Trailer
    I'm afraid you're going to need a custom axle. Many boat trailers use what's called a V-camber axle, where the center of the axle is bent into a V shape, in order for the keel of the boat to pass over it. If that's the type of axle you currently have, that's the type of replacement you'll need to get. If your axle is more or less straight, without a v-shaped bend in it, we do not offer an axle with the spring seats in the correct place (as you've seen). My first thought was that you could...

    Since your trailer's torsion axle is rated for 3500-lbs, and since a 4 x 8-foot trailer frame is unlikely to weigh more than a few hundred pounds, you should still be well within the axle capacity even when you have 2500-lbs of firewood loaded.
