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.


Note: Axle does not come fully assembled.


Pre-Greased Hubs

A trailer hub with the grease cap taken off shows greased bearings

The pre-greased hubs in this kit come with the bearings, races, and seals already installed, which makes for a faster install time and less mess to deal with. After you've put on the grease caps and lug nuts (included), you'll be ready to roll.


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"

  • Looking For Replacement For AL-KO-7230 Hub On Old Bison 2 Horse Bumper Pull Trailer
    Hello Chris, thanks for reaching out. Based on my research, it looks like the AL-KO-7230 is a hub for a 3,500 lb axle with a 6 on 5-1/2" bolt pattern. We do offer a replacement for this, and for that I recommend the following: - Trailer Hub and Drum Assembly - 3,500-lb Axles - 10" Diameter - 6 on 5-1/2 - Pre-Greased # AKHD-655-35-K

  • Replacement Axle for a 4,400 lbs AL-KO Axle
    Hey Shane! The closest axle we have to those dimensions is the Trailer Axle w/ Electric Brakes item # e73SR. It has a 86-1/2" hub face and a spring-center-to-spring-center length of 71-1/2". You may be able to get away with the hub face being slightly longer depending on your fenders but you'll need to use the Spring Seat item # TRSS300 to replace the ones that come with the axle.

  • Who Makes the Trailer Axle with Electric Brakes 6 on 5-1/2 - 86-1/2" Long - 6,000 lbs
    The Trailer Axle with Electric Brakes part # e73SR is made by AxleTek. If you're looking for a more well known manufacturer, we offer this same setup from Dexter as well, the Dexter Trailer Axle with Electric Brakes part # 8327826-EB which is also made here in the USA. These are both great options with similar specs, one just from a little more well manufacturer. It's really no different than going to a grocery store and seeing the store's brand and the more well known one. The Trailer...

  • Replacement Axle for Keystone Laredo with 85" AL-KO Axles
    Hi Gerald; you can use an axle like the # e73SR but you want to make sure the capacity is high enough. Also, this is 86-1/2" long so it will stick out an additional 3/4" on either side. Since your spring center measurement is different you will have to cut off the spring seats and weld on # TRSS300 to match your measurement. We do not have an axle that is an exact match for your 85" length. Typically when you replace an axle you want to match the capacity and the length. I'm assuming since...

  • Replacement for 5,100 Pound 86-1/2 Inch Long Overslung Dexter Axle
    When choosing a replacement axle you want one that is the same length. Since you have a hub face measurement of 86.51" a better choice would be an 86-1/2" axle. The # e65SR is an 89" axle so it is several inches longer. Also, you don't need a 6k axle, a 5,200 lb axle is fine. You can use a 6k axle but you need to keep in mind that this will not increase the capacity of your trailer. For an axle that is equivalent to the # e65SR I recommend the # e73SR, or if you just need the axle itself...

  • Recommended Replacement Axle for a ALKO T44 Axle
    Hey Ken! The closest axle we have to those dimensions is the Trailer Axle w/ Electric Brakes item # e73SR. It has a 86-1/2" hub face and a spring-center-to-spring-center length of 71-1/2". You may be able to get away with the hub face being slightly longer depending on your fenders but you'll need to use the Spring Seat item # TRSS300 to replace the ones that come with the axle.

  • Can the 6,000 Lb 86-1/2" Trailer Axle e73SR Be Flipped So the Spring Seats Are on Top
    The Trailer Axle with Electric Brakes part # e73SR has a slight arch to it which is designed to flatten when the trailer is loaded so you cannot rotate the axle to shift the spring seats on top. It's setup from the factory for underslung applications. In order to use this axle in an overslung application you'll need the Dexter Trailer Springs Over-Under Conversion Kit part # K71-385-00. This allows for a bolt-on swap without any cutting or welding required.

  • How to Determine if Trailer Axle e73SR Can be Used as Replacement
    Yes, so long as your current axle is 6,000 lbs and has the same measurements, if you are switching to electric brakes you can use the Trailer Axle w/ Electric Brakes - Easy Grease - 6 on 5-1/2 - 86-1/2" Long - 6,000 lbs # e73SR. To determine if the # e73SR will work for you, you'll need to measure your current axle from hub face to hub face and spring center to spring center. The hub face measurement needs to be 86-1/2" and the spring center measurement should be 71-1/2".

  • How To Find The Axle Information For a 2020 Lance 2465 Travel Trailer For a Replacement Axle
    Unfortunately, I have no way to look up the parts installed on your 2020 Lance 2465. Based on the trailers weight it appears you are going to have a 4,400LB axle which we currently do not carry in any size. If you can provide me with an image of the axle tag on the rear section of your axle I can let you know if we have any larger axles you can use in its place as an upgrade.

  • Do You Offer Custom Axles, How do I Get My Spring Seat Where I Need Them?
    Hello Ryan, I am very sorry but we do not make custom axles, they come directly from the manufacturers already put together. We used to do custom axles many years ago, but there were too many wrong measurements sent in so we no longer offer that service. What I suggest is to get the Trailer Axle w/ Electric Brakes - Easy Grease - 6 on 5-1/2 - 86-1/2" Long - 6,000 lbs # e73SR and have a professional welder add qty 2 of the # TRSS300 where you need them. We do not suggest cutting off the...

  • Recommended Replacement Axle for an Al-Ko 4.4k Axle
    Arie, it looks like the closest axle we have that matches your axle measurements is the Trailer Axle w/ Electric Brakes # e73SR. This axle has a 6,000 lb weight capacity, has a hub face to hub face measurement of 86 1/2", a spring seat center to spring seat center measurement of 71 1/2". You might be able to use this axle with a longer hub face measurement, but you're going to have to reweld your spring seats with # TRSS300.

  • Are Brakes of etrailer 86-1/2 Inch, 6,000 lb Axle Self-Adjusting
    The electric brakes of the Trailer Axle w/ Electric Brakes - Easy Grease - 6 on 5-1/2 - 86-1/2" Long - 6,000 lbs # e73SR are not self-adjusting, they are manual-adjust. To get the same axle with hubs and self-adjusting electric brakes you'd need the Trailer Axle Beam with Easy Grease Spindles - 86-1/2" Long - 6,000 lbs # e33GR, Easy Grease Trailer Hub and Drum # AKHD-655-6-EZ-K, Electric Trailer Brake Kit - Self-Adjusting # AKEBRK-7-SA, and Mounting Hardware # BRKH12.

  • Comparing The Total Weight Of A Fully Loaded 6,000 lb Axle Versus a Loaded 8,000 lb Axle
    Hello Eric. We do offer a fully loaded 6,000 lb axle part # e73SR that weighs about 136 lbs including the axle, hubs and brakes. Now, we do not carry and 8,000 lb axles, but we do carry a 7,000 lb axle part # e23SR that has the same axle diameter as an 8K axle, and the fully loaded 7,000 lb axle weighs about 150 lbs. Since we do not have any 8K axles I can't give you an exact weight, but it stands to reason that a fully loaded 8K axle of the same length would be about 10-15 lbs more than...

  • Do you Have a Trailer Axle With 85" Hub Face to Hub Face For 3,500LB Trailer Hubs?
    The closest axle hub to hub width we have to 85" is our 86-1/2" 5,200LB Axle # e73SR. This axle will not fit your current hubs you purchased but it does come with brakes and hubs already. To use the Hubs # AKHD-655-35-K & # AKIHUB-655-35-K you purchased and mount to the 85" hub face you would need to replace your axles with the Timbren Axle-Less Trailer Suspension # ASR3500S05. Otherwise you would need to visit a local axle dealer to have custom axles ordered. The Timbren has its own...
