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.

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.

E-Z Lube Spindles Make Lubrication Simple

The E-Z Lube spindles on this axle are meant to work with E-Z Lube-compatible hubs to make lubricating your bearings quick and easy. Each E-Z Lube spindle has a zerk fitting on the end. And every E-Z Lube hub comes with a grease cap that has an easy-to-remove rubber plug. Just pop out the plug on the cap to access the zerk on the spindle. When you inject grease into the zerk with a grease gun, the grease will flow to both the inner and outer bearings of the hub, lubricating the bearings and forcing out old, ineffective grease. Once you see new grease beginning to be pushed out, you know that your bearings are fully lubricated. This means that you can lubricate the bearings without the mess of taking apart the entire assembly.


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. This axle is also built with drop spindles, which will lower the ride height of your trailer to allow for easier 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"

Parts fit as advertised, very satisfied with purchase. I new nothing about replacing a trailer axle info on web site and support provided were excellent.
Definitely would recommend etrailer


Good axle and great customer service


I only received one axle when I bought two. I received all four hubs

Uh oh, thats not good. I have sent this information over to our customer service department for them to better assist you in getting the second axle to you.


Exact replacement for my Haulmark trailer. It delivered UPS and was in perfect shape. The hubs aren’t on the axle which is fine because it made it easier to install. It even came with a tube of grease. Could not be more pleased with customer service and the price. Will definitely use etrailer for future needs !!


Brent was awesome!! Helped me get the correct parts I needed. I ordered in a Wednesday midmorning and received everything the following day with free shipping. I will buy all my trailer needs from and will use Brent.


etrailer has always been good to work with and the purchase of this axle has been a positive experience as well


Delivered as ordered. No problems. Great follow up service


great service fast and accurate




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.


Everything was as expected and we were able to repair our trailer without issues. Shipping was prompt and the service was great. Received the package one day earlier than initially promised


After years of hauling firewood my Harbor Freight Trailer Axle fatigued and cracked. The Dexter Axle from etrailer got me back on the trail. Welded leaf spring seats on the opposite side of the axle at a spacing of 46.5 inches. The wheels stick out an additional 3/4 inch per side. The trailer now rides like a Cadillac. Very excited about putting my faithful trailer back in service, with a serious axle underneath that I have confidence in. The folks at etrailer very helpful and responsive. Thanks


I purchased a number of products from etrailer and I am very pleased with them all. The shipper lost my axle. When I contacted etrailer customer service, they handled my problem quickly and I had a replacement axle in a couple days. Well done!

The products were all of high quality and the assemble was much easier as a result. I have attached a few pictures of the build for those interested.

Thanks etrailer for your great products and service!!


I ordered this axle as a replacement for the one on my 1996 Haulin' 4x8 utility trailer. I'd neglected to maintain the bearings and when one went it destroyed my axle. This axle was an exact fit but the spring seats needed to be moved to the top of the axle. I ordered new seats and U-bolt mounting kit as well as the axle. I found a welder to remove the original spring seats and weld the new ones to match my application. Installation was a snap, I just followed the video included on the web site. Ordering my parts from etrailer really saved me $$ over the quotes I'd received from local shops.


I bought a axle, springs wheels, hubs etc. to build a utility trailer, I inadvertently had ordered incompatible hubs for the selected axle the person filling the order noticed this and contacted customer service to alert them of the issue who then called me to correct the problem. This saved me the time and expense of returning the part and delaying the project. great service, attentive, knowledgeable employees and great products.
Thanks E trailer.


Quick delivery with tracking link! Great product and price!! Easy process to install axle and hubs. I would have appreciated a torque specification for the U-Bolts and Lug nuts in the video. I didn't take the time to search other locations or Q&A.

Tip: 1-1/2 " PVC makes a great tool to seat the grease seals. I used my 28MM socket, it was very close to size. I decided to use 2" Schedule 40 PVC pipe to install the E-Z Lube dust seal. I have many tools however no wooden hammers.


Product seems to be built well. I was missing a set of outer bearings that I had to get from a local tractor supply due to time constraints. They were missing when shipped to me. I have been happy so far with this product as I have pulled my home built teaardrop on it. I have traveled over 3k miles with it as well as a tire set I purchased from etrailer.
Contender ST205/75R15 Radial Tire w 15"
Good sturdy wheels and tires and they look good in person.


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.


Really good solid axle... I needed the mounting tabs moved and had a metal fabricator do the work for $20.00. This was used on an old boat trailer that I turned into a utility trailer. Also swapped out the springs with ones purchased from etrailer too. To complete the package I ordered (3) 165/65-8 trailer tires. The trailer tows straight and hauls everything I've ever needed to.


Fits as it should. EZ lube hubs are much easier than having to repack the bearings. This is the second purchase I’ve made from etrailer and their service has been great.


I think I'd like to change the review to 3 stars and say:
Though the mechanical quality of the axle/hubs is great, whatever the axle and hubs are painted with comes off very easily. Simply removing tape would pull the paint with it. This will eventually lead to these parts rusting and you'll need to add an additional coat of paint to prevent rust. The paint quality is very poor


Solid axle with all the bolts and brackets to mount the axle quick and easy. Solid axle, should last a long time.


Used it on a homebuilt trailer worked great and tracks perfectly.


Product was top notch and customer service was even better. Was missing a bolt from package; it was overnight shipped at no cost to me. Will always do business from etrailer

  • Recommended Replacement U-Bolts For a 2020 Grand Design Imagine Travel Trailer With 3,500LB Axles
    I recommend using the CE Smith U-Bolt Kit # CE23002 to mount the Dexter 3,500lb axle under your 2020 Grand Design Imagine travel trailer. This kit uses zinc coated u-bolts, nuts and washers while the mounting plate is galvanized to increase life of the components. These will last longer than the U-Bolt Kit # APUBR-1 which is not coated especially in climates where you see more humidity and salt.

  • Are Hubs Pre-Assembled on Dexter Axle
    The hubs on the Dexter Trailer Axle Beam w/ Idler Hubs # 8327812-I do not come pre-assembled. You will need to put them on yourself. This is a 3,500 lb axle with EZ-Lube spindles with an idler hub that has a 5 on 4-1/2" bolt pattern and uses inner bearing # L68149, outer bearing # L44649 and grease seal # 58846.

  • Length Of Hanger For e54SR Leaf Spring On Home Made Trailer
    There is about 3-1/4" of space between the eye of the spring part # e54SR to the top of the lowest point of the spring. This is indicated by dimension D on the diagram I have attached. The height of the hanger you need really depends on the trailer axle diameter and the wheel size. I recommend to use Tandem-Axle Trailer Hanger Kit for Double Eye Springs part # APT5 which will give you the proper amount of clearance with the axle and the e54SR spring. This kit includes 3-3/4" tall hangers....

While you were looking for 88" hub face to face, this 89" shouldn't cause any issue and is likely the correct size axle that you were needing since 89" is extremely common. Either way, the 1" difference will not be a problem. For a complete axle and electric brake setup with 5 on 4-1/2 bolt pattern you...
