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.


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.


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.


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"

Video Transcript for Dexter Trailer Axles 20545I-EZ-72-15 Review

Today we're going to review part number 20545I-EZ-72-15. This is the Dexter Trailer Axle with the straight easy EZ spindles and the 5 on 4 1/2 Idler hubs. Now, this axle is 72 inches long. Has a 2,200 pound weight capacity. Now, this axle being will act as part of your trailer suspension system. You can use this to replace an axle on your trailer or to fabricate a suspension to fit your application. This is an Idler axle.

That means, there's no break mounting flanges installed on it. It is made of a high strength steel. Now, when we do ship this, we include the spindle knot, the D washer and the knot retainer one on each side. Also when we ship it, we actually need to show you how to protect it. We just don't ship it like that.

We would actually, the machined area. We would cover with grease and then wrap it to protect it. Then, we use this very strong sturdy card board tube. Now, we just slide over it and then we wrap it completely to protect both ends. One of these on each end.

Now, it does also come with these cast idler iron hubs. These are very sturdy and durable. Comes with all the parts pictured here on top of the table. Basically, it will come with the bearings. Now, for this part number, the bearing part number sizes is the same for in and outer. It would be two inter bearings, two outer bearings .

The races that the bearings would ride in or actually pre-installed in the hubs itself. You can see the outer races right there. The inner races right there on both these. Also comes with the two double up grease seals. Comes with two easy lube grease-caps and the reason I call this easy-lube caps is because they would have instead of the standard dome cap, they come with this that has a removable rubber plug on them. The reason they have that is you can pull it out and access the grease zerk fitting on the easy lube spindle. It also come with 10 of the half inch log nuts. The last thing that we send method is the marine-grade wheel bearing grease, a 14 ounce tube. Basically, this is used to grease the easy lube axles. Now, this does require a grease gun that will handle a 14 ounce tube. If you do not happen to have one of those, we also sell a grease gun as a related part on this product page. It's part number L30200. Then you put the tube in there to grease your axle. Now, this is a straight easy lube spindle. There's no drop to it. Now, on an easy lube spindle, they have a built-in grease to zerk fitting on the very end for simple lubrication. Basically, what's nice about the easy lube axle is you can install your bearings, your hub all together and then pump the grease into this fitting, pump it in there, it goes through the center, comes out onto the hole right here and will fill up the cavity and grease and lubes the bearings and everything. Once it's all installed, you can pump the grease into it. Then, if you need to grease some later on, it's just a matter if you don't have to disassemble the whole hub. Take the bearings out and you can just pump grease in through that fitting on the very end, very simple lubrication system. Also, I have actually, you might notice we have a bend near the center of the axle. They are manufactured that way to help create a certain camber angle. Basically having the center ride a bit higher and the sides lower. Allows this axle to give just enough to compensate for the load of the trailer. Basically, when you load down your trailer, they will push down on that and sort of even that axle out all the way across. Now, this will give you the correct angle of the wheels for your towing needs and allows your trailer tires to run along the pavement evenly and yet full contact across the width of the tread of the tire. The result is, you get excellent straight line acceleration for steady and line tracking. Now, this axle also has the spring seats welded underneath on the other side of the axle for mounting the lease springs to. This will be considered a under slung design axle which means they're underneath. So basically, that will give you a low ride height. Makes it easier to load and unload your trailer. Now, the spring seats and the spindles itself so both welded on to the axle. Now, on the axle, there are many ways you can measure the length of an axle beam. We're going to talk about the two most accurate ways which are the hub face to hub face and spring center to spring center lengths. Basically, hub face to hub face will gives you the measurement of what we claim this. The axle measurement, the length of the axle is really the hub face to hub face. Once these hubs are installed one on each end. If you measure from the base of one wheel stud on the hub go all the way to the other side and measure to the base of this wheel stud on the other one. That will get you your hub face to hub face measurement. Just to give you an idea, I don't have the hubs on but just to give you an idea where they would be on this axle. Would give you a overall length of 72 inches hub face to hub face. The other accurate measurement is spring center to spring center which is the center of the spring seat over here. Over to the spring seat on that end. That roughly gives you the width of your trailer. This one will be 58 inches. Basically, if you are replacing your trailer's axle, you should be able to figure out which axle you need by using these measurements using your trailer's weight capacity. The bolt pattern of your wheels on the trailer and any brake type if breaks are being used on it. To go over the specs on this part again, the weight capacity on this axle is 2,200 pounds. The hub face to hub face length is 72 inches. The spring center to spring center length is 58 inches. Now, the tubing outer diameter on this axle is one and three quarter inches. Spindle size diameter is one and one sixteenth. Now, on the idler hubs, the hub bolt pattern is 5 logs, 4 1/2 inch bolt pattern. Uses half inch diameter wheel studs. Use the half inch log knots that are included that holds your wheel assembly to here. Because of the hub flange diameter which is the width or the diameter of this hub flanger 6 1/2 inches. It is required that this will fit the wheel size of 13 inches to 15 inches. That should do it for the review on part number 20545I-EZ-72-15 the Dexter Trailer Axle with the straight EZ lube spindles and the 5 on 4 1/2 Idler hubs. .

I purchased an entire axle 'package' so I could put a leaf spring suspension under my vintage 1980 utility trailer that never had a suspension before. All of the products arrived securely packaged and I received everything I had ordered. The parts all went together exactly as they should, and the Etrailer video's and .PDF Instruction files were very helpful in assemblying everything. I'd definitely recommend these axle/suspension products! Steve 198340

All items were well packaged. I was happy that etrailer called me to let me know that a few items were back ordered and an expected shipping date to see if it still suited my schedule (which it did). I think all the items shipped the next day. Shipping was very fast and FREE. I will use etrailer for any future towing needs. Excellent communication and the helpful staff make this a great business to deal with. 183981

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


  • 72 inch Long Trailer Axle Recommendation with 2,200 lb Capacity that can Fit 14 inch Wheels
  • The difference is the mounting flange on the hubs. Axles that have larger mounting flanges like the part # 20545I-EZ-72-15 can fit the larger wheels, whereas the # 20545I-EZ-72-10 has a small flange that doesn't match up to the bigger wheels. What you would want to do is go with the axle part # T20BTR-EZ-7258 that does not have hubs with it and then use the hubs # 8-258-50UC1-EZ that has the larger mounting flange on it and will give you the 2,200 lbs capacity you want in the correct size.

  • Axle And Suspension Recommendation For Utility Trailer
  • I think the easiest way to get the parts you need for your trailer is to buy an axle kit that comes with the idler hubs, bearings, races, seals, grease caps, wheel studs, and lug nuts. For the weight you are saying you will be carrying I recommend starting with the Dexter Trailer Axle w/ Idler Hubs, part # 20545I-EZ-72-15. This system has a 5 on 4-1/2 bolt pattern so the tire/wheel combo I recommend is the Karrier ST205/75R14 Radial Trailer Tire with 14 inch White Wheel, part # AM32153....

  • Replacement Axle/Suspension for 4X8 Utility Trailer
  • In order to put larger wheels/tires on your 4 X 8 utility trailer you may need to change out other components, such as the axle, in order to have the required clearance between the tire and trailer frame. Please note that changing the wheels/tires to a larger size and/or with a higher weight rating will not increase the trailer's weight carrying capacity. We do offer longer axle kits that would have the spindles extend further from the outside edges of the trailer, such as # 20545I-EZ-72-15,...

  • Does Taskmaster Tire/Wheel Combo Have An Offset
  • The Taskmaster ST205/75D15 Bias Trailer Tire with 15 inch White Mod Wheel, part # TTWAS15B45WM is a Load Range C tire with a 5 on 4-1/2 bolt pattern. This tire/wheel combo has a zero offset. This is a 6-ply tire and has a maximum load rating of 1,820 lbs at 50 psi. The plot diameter of this wheel is 3.19 inches.

  • Recommended 72 Inch Axles And Brakes For Tandem Trailer
  • The 72 inch axles we offer have all got a weight capacity of 2,000 lbs. Also, none of the 72 inch axles have a brake mounting flange attached. You would need to have the components for a brake assembly installed on one of the axles. I recommend the Dexter Trailer Axle w/ Idler Hubs, part # 20545I-EZ-72-15, for the axle that you said you want free rolling. This has an EZ-Lube spindle with a 5 on 4-1/2 bolt pattern and has the bearings, races, seals and hubs included. This axle will work...

  • Replacement Hubs for Old Trailer That Uses Inner and Outer Bearing LM67048
  • First, thank you for providing those important details about your trailer. Bearing part # LM67048 is a common OUTER bearing for 6- and 8-lug hubs, but as an INNER bearing we offer only one 4-on-5 agricultural hub that takes this item as its inner bearing. That hub is part # AH15450ECOMP. I presume that you got the bearing part numbers from the original parts. Given the trailer's age it may be that someone previously substituted a different bearing for what was originally installed....

  • What Trailer Dimensions would the Dexter Trailer Axles # 20545I-EZ-72-15 Fit
  • The Dexter Trailer Axles # 20545I-EZ-72-15 that you referenced will fit a trailer that has the following dimensions. The axle it replaces will need to have a hub face to hub face dimension of 72 inches, you will need to measure the distance between the spring centers of the trailer, if that dimension is 58 inches it will connect to your suspension system. The wheel bolt pattern of your wheels will need to be 5 on 4-1/2 inch, and the capacity of this axle is 2,000 lbs. I attached...

  • What Information Is Needed From Existing Axle To Find A Replacement Axle
  • In order to find a correct replacement axle for your trailer, you will want to match the existing axle's spring center measurement, hub face measurement, axle weight capacity, and wheel bolt pattern. I have attached a diagram showing where to measure to find the hub face measurement and spring center measurement. My contact at Dexter was unable to provide any information on your axle based on the numbers you provided. There may be a sticker on your axle that includes a part number....

  • Replacement 72 Inch Long 2,000 Pound Trailer Axle
  • Trailer axle # 20545I-EZ-72-15 could fit in place of an axle with spring seat center spacing of 57-1/8 to 57-3/8 inches. At the very most the spring seats will have to be cut off and new ones, # TRSS175, welded on by a qualified professional welder for a nominal fee. Another option is an axle-less system, # A20RS545, which is rated for 2,000 pounds and comes with idler hubs. The suspension is built in. With this type of system you will not have to worry about replacing worn suspension parts.

  • How Long Would an Axle have to be to Use 15 Inch Tires on a Trailer that is 60 Inches Wide
  • An ST205/75-15 tire will be about 8 inches wide. Assuming the wheels you use have a zero offset the minimum length of the axle, measured from hub face to hub face, would need to be 70 inches. The axles that we have that are 72 inches long are all either 2,000 or 2,200 pound axles.

  • Choosing Replacement Spring Seats for Trailer Axle
  • It is possible to have new spring seats welded on by a qualified welder but we do not provide this service. We can get you new spring seats; these are shown on the linked page. Choose seats based on your axle diameter. For example, part # TRSS238 fits 2-3/8-inch diameter axles. We do not offer any beam axles with a spring seat spacing of 55-inches. The nearest to that dimension is the 58-inch spacing of the axles shown on the linked page, all of which are 2000-2200-lb rated. If you...
