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"

The axle seems good. Nice that the ball bearings were grease. We will see over the miles if all goes well. The delivery, besides the break assembly was quick. Not sure why the break assembly was not shipped with the rest.



by:

good products fast shipping good coustomer service thanks

by:

Exactly what I ordered packaged nice and pregreased bearings.



by:

Great value. I upgraded a 3500lb trailer and with the added brake it really helps. I use it to haul tools around so it handles the weight much better. Towing is a breeze now. Installation was easy as well. I will be buying more axles and parts in the future.



by:

Aside from not received complete order the first time, I will still recommend etrailer for all your needs



by:

Everything was going great on my new axle install today, until it wasn't. You shiped me the wrong lock washers for the brake backing plate. The correct nuts but the washers are to small. I'll have to pick them up because the customer is expecting the with to be done be today.



by:

Best thing I did was change axles to these. Went from 3500lb to these 7000lb with brakes on both. Tows and stops incredible.



by:

I wish I could give negative stars. My order arrived on time, but it was the wrong axle. The axle I ordered and paid for was a 3500 lb drop axle with electric brakes, they sent a bare 3500 lb drop axle. $[XX] difference. I immediately contacted customer service who required pictures of what I received. When I supplied them, they did not respond and even removed my order from their website so I can't track it to see if they're trying to make this right. They won't answer emails either because Ive sent a few. I'll try to get my credit card to refund me since they won't respond.



by:

Piece of cake to install. Pull out the old snapped axle install new axle. Bearings come pregreased.



by:

I was worried about ordering trailer parts from a new company online. Product showed up fast and on time. Beat most other product pricing. A courtesy email was sent when product was delivered, making sure I was satisfied, giving me a direct contact incase I had any issues.
I haven't used the product yet but everything looks good.
Will order trailer product again in the future.



by:

Wrong axle sent did not need the 4" drop down.



by:

Super fast shipping, excellent packing to protect the product. I have not opened all the boxes yet but plan to work on the install in the morning.



by:

The guys and gals at etrailer are the b est!



by:

Great product and customer service. Perfect replacement for my damaged axle. Would purchase from again.



by:

Not only is it not what I ordered 2 of the TA cayman parts and pieces in the advertisement. It doesn't say anything about coming in parts and pieces. I'm not a mechanic. Now I have to pay somebody to put it together. I think that's very poor business



by:

Paige was a huge help in getting me what I needed and fast!
Got my new axle in a day and was back on the road.
You will not be disappointed with etrailer!



by:

Product was exactly what I was after and helps me too get trailer back to work faster.



by:

Where the leaf spring sits on the axle was off about 1/4 inch had to finagle the axle abit but made it work.



by:

It's been a year since install and all is well! Thank you!



by:

I replaced the old axles on my trailer. I found these to be excellent quality. The install was not bad. I've taken a couple of long trips maybe 1000 miles one way and loaded. These axles head up perfectly.



by:

easy to order. reasonable price



by:

Everything was as described. Good products and fast shipping



by:

Good job. Good job. !!!!!



by:

No problems. It's working great.did a few trips no incidents.

  • 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.

  • 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".

  • 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 3,500 lb Axle System with Suspension, Brakes, and Hubs with 5 on 4-1/2" Bolt Pattern
    For a standard 3,500 lb axle the closest spring center measurement we have is 74" on the axle # e43SR so you would have to have the spring seats cut off and welded on at the proper locations if you went with this axle. To avoid modifying a brand new axle I recommend going with the Timbren Axle-Less Trailer Suspension System # A35RS545E which also comes with brake and hub assemblies with a 5 on 4-1/2" bolt pattern. Each axle piece has it's own AEON spring so it gives your trailer a more...

  • Upgrading 4400 Pound Axle To 6000 Pounds
    I have a solution for you. I suggest going with the Dexter Trailer Axle Beam with E-Z Lube Spindles - 86-1/2" Long - 6,000 lbs # 8327826 and the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shocks - Tandem 8K, 3-1/2" Axles # RM-2470-2580. These will work with the Dexter axle. You could do this however, it might not be a good idea. Increasing the capacity of your trailer's suspension will not increase the trailer's capacity. The frame and other parts may be rated lower than 6000...

  • 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 Correct 5,200 lb or 6,000 lb Axle & Equivalent 8-14.5 Tire
    Based on the bearings you gave, that is either a 5,200 lb or 6,000 lb axle, but it's not possible for me to know specifically, that's just the capacities of the hubs that have those bearings. Realistically, to get the exact capacity you'll need to contact Dexter with the serial number. After that, to get the right 5,200 lb or 6,00 lb axle you'll need to you will need to know the dimensions of your current axle's hub face to hub face and spring center to spring center. For example, the...

  • 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...

  • Do Dexter Axles With 86-1/2 Inch Hub Face Have 71-1/2 Inch Spring Centers
    Each of the 86-1/2 inch axles we offer, such as the 5,200 lb Dexter Trailer Axle w/ Electric Brakes # 8327816-EB and 6,000 lb part # 8327826-EB have 71-1/2 inch spring centers. So what you would have to do is get new spring seats welded on at the correct position, and for that use Spring Seat for Typical 5,200-lb to 7,200-lb, Round Trailer Axles with 3" Diameter # TRSS300.

  • Option For Replacing 6k Axle With Spring Center Length Not Available
    I sincerely apologize but we do not have axles with that measurement. The only option I can offer is to replace them with the Timbren Axle-Less Trailer Suspension # TASR7KS01. This removes having to find an exact length of axle, and you would also need Hub & Drum # AKHD-655-6-EZ-K.

  • 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.

  • 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...
