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.

With Alex's assistance and knowledge of my trailer requirements, I installed two 3500 lb axles. These axles are superior to any others that I was shopping for, and with a combined GVW of 7,000 lbs my trailer is now suited for any medium sized load.


Perfect fit, nice axle and fast delivery. I liked it so much I ordered another a day later to replace the front axle. My 30 yr old tandem trailer's axle broke at the wheel, so I went to a local store which doesn't stock them anymore. Could of ordered a so so axle for $94 + $28 shipping and wait 2 weeks but needed it fast. I went to a major trailer sales & service shop and told "maybe we could get one for $250" with no call back. I decided to check out etrailer and was surprised to see Dexter axles that fit my trailer for $140 with FREE shipping in 3-4 days! Ordered Sat. night, got it Wednesday afternoon, and installed it (with brakes) in an hour. Only problem I had was determining if spindles would fit my hubs. They stated "1/16th spindle" and must be industry talk but french to me. So I had to look up bearing #'s they listed to check bearing sizes to make sure they fit my hubs. A little more time but not a deal breaker. The best part was the huge difference in ride with just one new axle. Always had bouncing loaded or not, but now with just one axle the ride is smoother no load and with my 4000 lb tractor on it. Can't wait to get the 2nd axle on that arrived today. First two pics show the difference between the old straight axle and the new dexter axle. The third is a pic of my 2nd axle, oh well. Etrailer is my new go to place for trailer parts. I have 7 trailers.


Axle arrived in perfect condition, was also an exact fit for my Top Hat Trailer.
Your staff was of great help finding my right axle.
I would recommend etrailer to everyone.

Axle is working out great. Easy to install, fit perfectly.

etrailer customer service for returns and their products as a whole are third rate at best. Every product arrives damaged from terrible packaging and handling by etrailer. Customer service sometimes responds and their return policy is garbage at best. buy elsewhere


Came in bent

Axle should have a slight bend to it.
-- Etrailer Expert Sierra K - 10/12/2021


Specs. matched exact to the broken axle and was easy to install. I was surprised that the axle was pre-wired although it was not replacement of the brake axle on my trailer. Hub fit nicely and trailer is now ready for the next haul job. Delivery was as promised.

The axle has been a good replacement and has worked as it should.
Ronald E - 08/13/2021


Local supplier said this part was not available for months, E trailer delivered in a few days.

Trailer axle was a perfect fit and after going to several local dealers first, etrailer was the only company I could find the parts I needed during Covid. Parts have had no issues for a year of service.
Dalton R - 01/14/2022


A was a great product fit perfectly arrived in great condition and timely manner i im super happy great job guys


easy peasy

good price quick deli


Just what the doctor ordered and fast d elivery.


Great service as always out of etrailer. I ordered 2 new axles for my car carrier, great specs on your webpage made for a perfect match. Items arrived in 3 days, heavily wrapped and will add that the end of the axles which could rust if not installed soon were covered in grease, a nice touch to insure no damage. Thanks as always for having a great source for all things trailers!...

one year later no issues at all
Michael - 06/08/2020


working great after 1 year of use and several thousand miles put on the axle.


Etrailer was quick to ship and and axle was a perfect fit, axle was good quality.
i have used them before as well. they are a good company.
thsnks jack


Axle is perfect. Holding up well after a year plus.


I'm very pleased with all of my purchases from eTrailer. Everything has seemed to be of excellent quality and value. The wiring kits and directions were very well thought out and one of the projects I completed would not have been possible had it not been for the excellent videos on the website.

I'm an eTrailer customer for life!


The axle fit like a glove, It took about an hour and half by the time I put the tools away
I only had two jack stands make sure you have four or cinder blocks will work also and a new bearing and U bolt kit.
I was going thru one used tire a week because the axle spindle was bent now this trailer is riding smooth!.

They shipped the axle right away, very happy with the product and service from etrailer.


Friendly, curteous service and prompt receipt of ordered parts. I have told many people in Kodiak, Alaska about your superior
service, prices and demeanor. Thank you!


Personal service was great. Received a call regarding an address issue; person from etrailer wanted to make sure address was correct prior to shipping. This ensured order received without delay. Axels are a perfect fit; on-line videos for installation are very helpful. All your videos are well done; informative and helpful. Prices were better than any local suppliers in the area. I still trade with local businesses, but for large purchases I go to etrailer.

The seal puller is a must have tool, works great!!


The axel I bought was of good quality, cheaper than buying a local, and the shipping was free! I wish the website would have prompted me to buy the extra items I needed. Example: bolts and plates to attach the axle to the spring. Bolts for the brake assembly, wheels, tires, Springs etc. I did not need all those things but it would be nice to have them pop up as choices.


My utility trailer bearings locked up and welded to the spindle, along with the seal. Repair would have cost as much as a new axle. Ordered this axle Thursday night around 10pm, Arrived Saturday morning around 10am. They were running a special and regular shipping was free but I paid for 2nd day delivery which was discounted. Actual product was as described, wrapped well end to end with rubber protectors over spindles. Installation was a snap and took about 20 minutes start to finish with no help. Still waiting on hubs to be delivered but I am expecting the axle to do what it is supposed to. I will definitely use etrailer again, and should I need another axle, I wouldn't think twice about ordering this one again. Excellent business with an excellent product.


Needed a new 3500 pound axle for a 30 year old utility trailer, ordered a new one plus the u bolt kit, items were shipped the next day and received 3 days later.
Axle was a top quality Dexter axle. Both items were well packed for their trip. I will most certainly order all of my trailer parts from these folks, Great service, great parts and great follow up.


This is the second time I ordered off of Etrailer. Renée did an excellent job of putting together all the parts that I needed and they were all in stock. And I received my trailer axles hubs and bearings in four days almost all the way across the country Etrailer does an excellent job with quality parts


The axles I needed were easy to order, great descriptions etc. I realize the hub's and brake drum were shipping seperate and required assembly but that's minor, everything was there. My second order had some minor issues with availability but I talked to Sandy J and she was a pleasure to work with. My corrected order came in 3 dsys. Very pleased thus with e trailer and will be ordering parts there again.


the axle that I got from etrailer was as advertised and delivered promptly. The price was excellent and overall I am very satisfied and will be a return customer.

mike k - 07/18/2016


very pleased with this product .precise measurements .arrived in a timely notch quality .would definatly buy from etrailer again

  • Difference Between Dexter 3,500 lb Trailer Axles, EZ Lube vs. non EZ Lube
    Brake flanges on 3,500 lb axles are going to be the exact same between a Dexter axle and Lippert but sometimes the Al Ko options are different. I believe you are asking about the price difference between the Dexter 3,500 lb axles part # T3584F-8974 and # T3584F-EZ-8974 though which that comes down to the spindle style. The more expensive EZ lube spindle axle has a grease fitting on the end of it that allows you to easily pump grease into it whereas the other option does not and requires...

  • Replacement 3500-lb Trailer Axle for 2007 Spree by KZ Tandem Trailer
    If your KZ Spree trailer's 3500-lb-rated axles are bent from damage or from overloading them beyond their weight capacity then they should be replaced. This will not only restore the trailer's handling but it will also prevent continued issues with uneven tire wear. Usually an axle that was bent from being overloaded will result in more wear on the inside edges of the tires. A new axle has a light upward bend that levels out under load. Our two 3500-lb-rated axles without hubs are displayed...

  • How to Determine the Axle Capacity of a 1978 25 foot Monitor Travel Trailer
    Based on the diameter of the axle that you listed most likely it is a 3,500 lb axle. However, there should be a plate near the coupler on the frame of your trailer that should have the axle and trailer capacity listed. That would be the final authority on the capacity.

  • What are the Wires at Each End of Dexter 3500 Pound EZ Lube Axle # T3584F-EZ-8974
    The wiring that you see on axle # T3584F-EZ-8974 is for electric brakes. So you would run the wiring back to one side of the axle, make the splices for the brakes on that side and, instead of running your own wire, it is already run through the axle. So all you will have to do is splice in the brake magnets on the other side. Take a look at the video I have linked. It is mentioned near the end of the video.

  • How to Find Proper Length Replacement Trailer Axle
    In order to find the proper replacement axle, you'll need the hub face to hub face and spring center to spring center dimension of your existing axle (see diagram.) We offer a limited amount of off the shelf axles, if you could provide the abovementioned dimensions and the inner and outer wheel bearing reference numbers, I'd be happy to check to see if any of the axles we offer would work for you.

  • Axle Recommendation with 74 inch Spring Center Dimensions
    Of the axles that we carry the part # T3584F-EZ-8974 that you referenced would be the closest one we carry to what you would need. The spring center measurement is the same at 74 inches. The issues is that this axle measures 89 inches from hub face to hub face so it would be 2 inches shorter than what you currently have. If the wheels and tires could be an inch closer to the frame on your trailer on either side without causing interference this axle would work well for you. Otherwise you...

  • Replacement Axle for a 1994 Jayco Eagle 8 with Dexter Axle
    It sounds like you will need a 2,000 pound axle. We do not carry the torsion straight axles though. We do have axle-less systems that work the same as torsion axles. I have included a link to them for you to view. The great thing about the axle-less systems, besides the better ground clearance, is that you don't have to have a specific axle length and in your case you would not have to add suspension components like you likely would if you went to a straight axle.

  • Troubleshooting Trailer Wheels that Toe Out Toward the Front
    Sounds like a problem with the suspension. Check the suspension for worn out components are holes that are egg-shaped instead of round where the suspension components come together. Having your trailer checked is a good idea to verify there are no broken parts such as the axle or springs. I would recommend looking for a company that sells trailers and/or RVs and has a service department. These guys will probably have the most comprehensive hands on experience with your issue. The other...

  • How Much More Clearance Under Trailer Using Torsion Axle With Negative Angle
    In order for you to realize more clearance under your trailer, using torsion axles with down degree angles will give you more clearance. On a system that has a 10 degree up axle, the center line of the spindle to the bottom of the trailer frame is approximately .96 inches. That is based on a newer system. If you have an older system on your trailer that measurement may be much less. For a 10 degree down you would have a difference of 2.08 inches. For 22.5 degree down, the difference...

    We do offer axle beams alone and also complete axle kits that include hub/drums, brakes etc. All can be viewed by clicking on the included link. I also was unable to find a cross-reference for your axle number 4330537. This may be a production code rather than a part number. You can certainly change out your axle to a higher-rated part, such as the 3500-lb-rated Dexter part # T3584F-EZ-8974, but this will NOT necessarily increase your trailer's capacity.

As long as the Dexter axle has the same capacity as the Lippert axle and the same hub face and spring center measurements, it will not be a problem to have them both on the same trailer.

    Trailer axles should have a bow in them that points up in the center. This is so when weight is placed on it, it flattens out. If there is not enough weight on the axle the bow will still be there and the tires will toe in like you are describing. But that should not cause excessive heat build up. It seems like there is either not enough or no grease in the hub. Or If that bow is bad enough it could be stressing the bearings very badly. We have several axles, see link, but they are the...

  • Trailer Suspension Makes Noise When Making Sharp Turn While Backing up
    If everything checks out on the suspension and shows no sign of damage you should be good to go.

If everything checks out when you are towing normally, you should be fine.

  • Replacement Axle for 1981 Wells Cargo Enclosed Trailer That Shows Uneven Tire Wear
    Uneven tire wear can indicate any of several problem conditions. If a tire tread surface wears on its outside edges more than it does in the middle of the tread then this generally indicates under-inflation. If it wears more in the middle than on the sides this indicates over-inflation. If the two tires on an axle both have more wear on the inside edges of the tread then this usually signals that the trailer has been overloaded. A bent spindle is of course another possibility.

  • How Does EZ-Lube Spindle Grease Hub Components
    The EZ-Lube spindles have a hole in the spindle so that it fills the hub components from the back of the inner bearing.

Each of the spindles is rated for 1,750 pounds for a total of 3500 pounds for the whole axle.

There's really no way to shim hubs as they are only held on by the one spindle nut at the end of each axle. The 4 bolt mounting flange you are referring to is for the brake assemblies to mount onto. You would not want to shim this flange as the assemblies need to mount completely square relative to the spindle and installing shims would throw that all of and wouldn't...
