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.


Dexter Axles

Dexter 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.

Video Transcript for Dexter Trailer Axles T3584F-8974 Review

Today we are going to review part #T3584F-8974. This is the Dexter trailer axle beam with the standard spindles. This is 89" long, has a 3,500 pound weight capacity. Now this axle beam will act as part of your trailer suspension system. You can use it to replace an axle on your trailer and you can also use it to fabricate a suspension to fit your application. It is made of high strength steel construction. The other nice thing you might notice on axles, they will have a rise in the center of the axle.

It is hard to see on this video, but basically it will rise in the center and then go down. The reason they do that is to ensure the proper camber angle. In other words, this will ensure that the angle of the wheels on your trailer are correct for your towing needs. Basically this bend being higher, what will happen is when you put a load on the trailer and it weighs down on it, it will actually straighten that axle out some and then it allows your tires to have even road to tread contact across the width of the tires. This is good for straight line acceleration and steady control towing. You also notice the spring seats.

There is one on this end and one all the way down here on this end. Basically, those are welded to the underside of the axle. This is for mounting your leaf 00:01:13 springs to. The under slung design is nice because it gives you the low ride height and that makes it easier to load and unload your trailer. If you notice the spindles. They are a straight spindle.

There is no drop to them. They are a standard grease application. It does include the castle nut, the D washer and the cotter pin. We ship them with that all included. When we do ship them, they are protected. They don't ship them just like this bare.

What they will do is put grease over it to protect it and then they will bubble wrap over that, and then they will have the corrugated tube that will go over that and be wrapped around it so it protects it from getting damaged during shipping. The spring seats down here. The brake flange is right here. The spindles are all welded on. Also if you will notice, there is wiring right here. At this end is a loop of wire and one down at that end. That is basically the wiring that goes through the axle. That is used for your electric brake hook up. The weight capacity on this axle is 3,500 pounds. The tubing outer diameter right here is 2-3/8". The spindle size diameter is 1-1/6". If you notice, I did mention that it has the 4 bolt brake flange for connecting your brakes to. Also, there are multiple ways to measure the length of an axle beam. Basically, the two most accurate ways are going to be hub face to hub face and spring center to spring center. The hub face to hub face is when you have your hubs mounted on each end. You will measure from the base of one wheel stud on one hub, go all the way to the other side and measure to the base of the wheel stud on that opposite side of the axle. This axle, I do not have any hubs mounted on, but just to try and give you an idea. We're going to run this ruler where it is roughly going to be about 89" is where your hubs would run hub face to hub face. The other measurement would be the spring center to spring center length. On this one you can measure because the spring seats are welded to the axle. Basically, you measure from the center of this spring seat all the way to the center of the one on the other end. Actually this measurement will also give you the approximate width of your trailer. So basically you can see when we do center to center, right at 74". If you are replacing your trailers' axle, you should be able to figure out which type axle you need by determining the trailers' capacity, the bold pattern of the wheels that goes on the axle, the brake type and then the two measurements I mentioned, the hub face and spring center lengths. That should do it for the review on part # T3584F-8974. This is the Dexter trailer axle beam with the standard spindles. It is 89" long and has a 3,500 pound weight capacity. .

Ask the Experts about this Dexter Trailer Axles
Do you have a question about this Trailer Axle?


  • Castle Nut Torque Spec for Trailer Axle
  • When installing the castle nut on the end of the spindle, there is no specific torque rating. The nut is ran down until there is no side to side play in the hub, and then backed off to the next notch in the castle nut so the tang washer or cotter pin can secure the nut. Over-tightening the castle nut can damage the bearings, races and spindle. If you click on the video link I provided, and fast forward to the 4:45 minute mark, you can see the procedure.

  • Can a Trailer Rated for 2,990 Pounds be Upgraded to 3,500 Pounds
  • Yes, you can replace the axle on your trailer with one that is rated higher. This will ensure that the axle is rated for more than enough weight. But you will also need to upgrade the suspension, tires, and possibly the wheels and the trailer coupler depending on what they are rated for now. But we can start with the axle. I have included a link to the axle options we carry. If you want to go with a 3,500 pound straight axle beam all the ones we carry are 89 inches long such as # T3584F-8974....

  • Can a Trailer Axle be Put On a Truck Bed to Make a Trailer
  • First, I am pretty sure you don't have to change the axle out if you are making a trailer out of a truck bed. You will want to check the laws in your state/area though. The highest capacity straight axles that we carry are rated for 3,500 pounds which likely exceeds the capacity of the truck bed. For a trailer axle that will accept a hub with a 6 on 5-1/2 bolt pattern you could use # T3584F-8974 with hub # 84655UC1. Or EZ lube axle # T3584F-EZ-8974 with hub # 84655UC1-EZ. Both of...

  • Recommended Axle And Fenders For Karavan Trailer
  • The 3,500 lb axle we offer that meets the 82-5/8 flange to flange measurement you mentioned you need is part # T3584F-8974. The spring to spring measurement for this axle is 74 inches. None of the axles we offer in this weight capacity have the 76 or 78 spring-to-spring measurement. The U-bolt mounting kit I recommend is part # APUBR-1. This includes the U-bolts, plates, and hex nuts needed for installation. If you are looking to buy new springs for your trailer you can check out...

  • Can I use a Rectangular Axle with Round Axle on Tandem Boat Trailer
  • I spoke with my contact at Redneck Trailer Parts and he said that yes you can use a rectangular tube axle with a round tube axle on your tandem boat trailer as long as the hub base diameter and spring center diameter are the same. You will also need to add U-Bolts. I have included a link to all of our U-Bolt kits for your to check out.

  • Information Needed to Choose Replacement 3500 lb Trailer Axles
  • We do offer a limited selection of 3500 lb trailer axles. To determine if any of them would be compatible with your trailer, I'd need to know the hub face to hub face dimension and the distance between the spring seat centers. I'm not familiar with the bolt pattern you mentioned, are you sure it's not a 5 lug on a 4-1/2 inch bolt circle? If you're wanting to reuse your current hubs, I'd need to know the inner and outer bearing reference numbers, and whether the trailer has brakes. I'll...

  • Recommendation of Trailer Hub and Drums and Axles
  • The trailer hub and drum assembly # 845476UC3 includes bearings and races from Redline. They are made in China. I would assume you have 5 on 4-3/4 inch bolt pattern but you will need to replace the spindle. Welding on a new spindle is a precision trade craft requiring a special jig installed by an experienced professional. Otherwise, you could continue having the same problem. Depending if you currently have a round or square will determine which spindle you need. If it's round, you...

  • Purpose of Wire Inside Dexter 3500-lb Axle
  • Dexter's 89-inch/3500-lb axle kit # 35545E-ST-EZ-89, for example, includes electric drum brake assemblies so it will have wiring in place. Electric brakes are simple to wire; there are only two pigtail leads from each brake and either one can be used for ground or +12V. Generally electric brakes should be wired with 10-gauge duplex wire like # 10-2-1. The linked article on electric brakes may be of interest to you.

  • Availability of 3500lb Axle 89 Inches Long 74 Inch Spring Centers
  • We can come pretty close to the dimensions you mentioned. Dexter Axle # T3584F-8974 is a 3500 lb capacity axle with a hub face to hub face dimension of 89 inches and a spring seat center to center measurement of 74 inches. This isn't the exact spring center dimension you were looking for, but it would be very easy to grind off the old seats and weld replacements like # TRSS238 into place. The standard spindles are compatible with a L648149 inner and a L44649 outer bearing. If you prefer...

  • Trailer Tires Showing Excessive Wear on Inside Edges of Tread
  • Typically a trailer axle will have some camber in it - some bend - such that when it is not loaded the tops of the wheels bow outward slightly, with the outside edges of the tire treads making first contact with the ground. This allows that when the trailer is loaded with weight the axle will be pushed downward to a flatter position with the tire treads level on the ground. Please refer to the linked photo showing an axle and its camber. With your trailer unloaded look at it from the...

  • Availability of the Dexter Axle # 35545I-ST-89 Without Hubs
  • Sounds like you don't need the hubs that come with the Dexter Axle part # 35545I-ST-89 and you just want the axle. For that you would just want the part # T3584F-EZ-8974 that you referenced.

  • All of the 3500-lb trailer axles we offer have a hub-face-to-hub-face length of 89-inches. For an axle with standard spindles I recommend part # T3584F-8974. The spring-center-to-spring-center measurement is 74 inches. If that matches the system you have on your camper then this will work well for you. Keep in mind the hub components are all sold separately and should be replaced since you are getting new spindles. The U-Bolt Mounting Kit I recommend for this axle is part # APUBR-1....
