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.

etrailer Axles

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.

Thoroughly Tested for Safety

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.

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"

Axle fit perfectly. Delivered quickly. And after a year it is still working great.


Awesome, I will never buy an axle from anyone else. I will also tell my friends.

James W.


It’s been working great. I am so glad that I found your website. There are a lot of companies that will take your money and give you a bad product. Not you guys! Keep up the good work!


5 stars for looks, apparent quality, and ease of assembly. My only complaint is the axle came with the zert fittings installed on the ends of the axles. This is convenient, but both were non functional upon arrival. One was slightly damaged, and both had the rubber protective material jammed in the grease fitting that I couldn’t remove. I had 2 extra zert fittings in the shop, so quick change and no problem. Maybe these could be shipped uninstalled?

Other than the small, minor complaint, the axle and hubs look great.

  • Does Trailer Axle with Idler Hubs e32GR Come With Spindle Washer Trailer Axle with Idler Hubs
    Appreciate the purchase of the Trailer Axle with Idler Hubs - 5 on 4-1/2 Bolt Pattern - 72" Long - 2,000 lbs # e32GR. This axle and hub combo does not come with a spindle washer, and one is not actually needed as the castle nut pushes directly onto the idler hub bearing.

    You'll want to look at the weight rating sticker at the front of your trailer for that info.

Some people will look at the sticker on the middle of the axle which is a good way to estimate the load rating if your trailer doesn't have that sticker on the tongue for whatever...

  • Parts Needed to Install 7-Way and Brake Controller in 2019 Kia Sorento
    We can help you install a 7-way and brake controller in your 2019 Kia Sorento but you do need to first start with a 4-way like the part # C56256 and then convert it to a 7-way with the part # ETBC7 so that you can install a brake controller like the Brake EVN # TK63VR. This comes with everything needed to convert to the correct connector and wire up a brake controller. For a trailer hitch then the etrailer # e98843 would be a great option.

  • Replacement Bearing Kit For a Pop-Up Camper That Uses L44649 Bearings
    The etrailer Axle # e32GR uses a Easy Grease Trailer Idler Hub Assembly # AKIHUB-545-2-EZ-2K which will use the Bearing Kit # BK1-150. I do recommend pulling one of your hubs apart to verify that the bearings and seals match the spindle on your axle. For this bearing kit to fit you will need a BTR Spindle # TRU44FR on your axle that has a 1.5" landing for the grease seal and a 1.063" straight spindle for the inner and outer bearing. If you have any other measurements please let me know...
