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.


Dexters

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.

  • Replacement Axle for LoadRite Boat Trailer
    I looked up the LoadRite parts and they have torsion axles and traditional spring axles. If you have a trailer that has the springs centered at 58 inches on center and is 1-1/2 inches square, then the axle is a 2,000 lb axle and you would use the Dexter Trailer Axle Beam with Standard Spindles - 72" Long - 2,000 lbs # T20BTR-7258 with hardware # APUBR-10. If you have different axle, give me those measurements and I'll try to assist by comparing parts. Overall length, style of springs...

  • Installing Dexter Trailer Axle T20BTR-7258 In Application Where Spring Seats Need to be Opposite
    Since you need the spring seat on the opposite side of the trailer axle part # T20BTR-7258 that you referenced you'd need to either have the spring seat that's on it removed and attached on the other side of it or have new ones like the part # TRSS175 welded to the opposite side. The bow in the axle allows it to flatten out once the weight of the trailer is put on it. This is why you can't just flip the axle over.

  • Replacement 2k Dexter Axle for Boat Trailer
    Hey Craig! Have you already identified the axle through Dexter or measured it yourself? If it is 72" long with a 58" spring center and uses # L44649 inner and outer bearings then the # T20BTR-7258 will work as a replacement. You can also keep your current hubs. If your length and spring center match but you have # L44643 bearings you need the # 20545I-EZ-72-15 that comes with new hubs.

  • How to Choose Correct Trailer Axle
    Hello James, In order to choose the correct replacement axle for your trailer you will need to know the dimensions of your current axle's hub face to hub face and spring center to spring center; I have added a link below to a video which walks you through how to measure. The other thing you need to know is the weight capacity of the axle you need, which should match or exceed the GVWR of your trailer. Just as an example, the Dexter Trailer Axle # T20BTR-7258 has a 2,000 lb capacity and...

  • Why Dont 2,000 Lb Trailer Axles Comes with a Brake Mounting Flange
    A 2,000 lb trailer axle like the Dexter Trailer Axle Beam part # T20BTR-7258 is not going to come equipped from the manufacturer with a brake mounting flange because of the weight of the trailer it is designed to be used on. However, most qualified welders can add the brake mounting flange part # 4-34 for a very small fee. The Dexter Trailer Axle has a 2,000 lb weight capacity, 58" spring center, and 72" hub face length. It uses a L44649 bearing on both the inner and outer seats. Once...

  • Replacing Dexter 2K Trailer Axle with 70" Hub Length and 58-1/2" Spring Seat Length
    The Dexter 2,000 Pound Axle # T20BTR-7258 that you referenced is the closest standard axle beam option we have available to the specs you listed for your existing/old unit and it should work well as a replacement. The slightly longer 72" hub face length is just going to push the hubs a bit further out (1" on each side), which won't affect anything with regards to function but just something you should be aware of. It would also allow you to get wider tires down the road if you ever wanted...

  • Can I Relocate The Spring Seats On Axle To Where Spring Leafs Are Located To Widen Trailer
    When positioning a 2000 pound trailer axle like # T20BTR-7258, it is recommended that the hub face to spring seat measurement falls between 5.75" to 7.625" on each side. (11.50" to 15.25" total on both sides). (see picture). As long as your axle is within those parameters you will still be able to utilize all 2000lbs weight capacity of the axle. If you go beyond those measurements you could jeopardize the integrity of the axle.

  • Spindle Washer Needed For 2000 LB Axle With Standard Spindle

  • How to Determine Correct Replacement Axles for Older Trailer
    When it comes to replacement parts for trailers - no matter if they're cool vintage ones like your 1968 Silver Streak Sabre or new, off-the-lot trailers - there isn't any type of database or other method that is available to know what is needed, which means some information and measurements are needed to make sure you get the right parts. I wasn't able to find an exact GVWR of this trailer, but it looks like it is in the 3,500 lb range; you'll need to verify this but if it is true, that...

  • Can I Put Hydraulic Brakes on a 2,000 lbs Axle?
    Yes and no. The issue with 2,000 lbs axles like the Dexter Trailer Axle item # T20BTR-7258 is that they don't come with a brake flange item # 4-34. You can add one but this is something you will need to rely on a professional welder to do if you don't have experience. If you would like to give me some dimensions of the axle you're needing and your lug pattern I would be happy to make some recommendations for you. Feel free to email me directly.

  • Is There A 2,000lb Axle With A 72" Hub Face And 59" Spring Seat Measurement
    The axles we carry with a 72" hub face measurement, like Dexter Axle # T20BTR-7258, only come with a 58" spring seat measurement. I recommend double checking your spring seat measurement to see if it really is 59" and not 58" when measuring from center to center. If it really is 59" then you can just have a local fabricator custom make you an axle or just have them cut the spring seats off of the axle and weld them back on with a 59" spacing.

  • Replacement Axle for 2,000 Pound Dexter Axle on a Pop-Up Camper
    We have straight axles that are close to the measurements you have provided, see link, but the spring seats would have to be moved and none of them have brake mounting flanges. I propose a different approach by using a Timbren axle-less system # ASR2KHDS01. This system will provide the "axle" as well as the suspension in one unit plus the suspension part will not wear out nearly as quickly as traditional leaf springs because the rubber won't corrode. They are also set up for electric brakes. The...

  • Info Needed to Pick Out Replacement Axle, Leaf Springs, Hub/Drum, and Brake Assemblies for Trailer
    To pick out an axle you'd need to know the length of the axle from hub face to hub face as well as the distance between spring seat centers and the capacity of the axle. For leaf springs you'd need to know the axle capacity and the current length of the springs. For the hub that is also based on the axle capacity and the trailer wheel bolt pattern. Once you know the correct hub/drums you'd be able to find the correct brake assemblies.

  • Reducing Overall Trailer Weight By Replacing Beam Axle with Timbren Axle-Less Suspension
    A standard beam axle made for a leaf spring suspension will vary only slightly more in its actual weight, depending on its carrying capacity, than two Timbren axle-less systems of different capacities. This is because as weight ratings increase a beam axle tends to have a larger diameter and more steel, which makes it heavier. With Timbren kits there will be a bit less of a weight difference. For instance, Timbren 3500-lb-rated kit # ASR35HDS02 has a shipping weight of 152-lbs, while their...

  • Determining The Correct Replacement Axle For Camper With Bent Axle
    I would be happy to help you find the correct replacement axle for your trailer, but unfortunately my contact at Dexter was unable to find any information on your axle via the serial number you provided. Instead you will need to measure your current axle from hub face to hub face, spring center to spring center, and determine its axle rating. The easiest way to determine the axle rating will be looking for it on the axle tag where you got the serial number, but if it is unreadable then...

  • 72 inch Trailer Axle with 2k Capacity and Hub/Drums to Match
    We have 72 inch axles that are 2k rated with idler hubs as a single part number but none that have the hub/drums on them so you'd need to order an axle with spindles only in that configuration and then add the hub/drums and assemblies like with the # T20BTR-7258 and then hub/drums # 8-257-5UC3 and then for assemblies # 23-47 and # 23-48. Then for a wheel and tire that's 15 inch with the bolt pattern you are needing the part # AM32418DX would be a great option.

  • Is There a 72 Inch Long Trailer Axle with 4-Bolt Brake Mounting Flange
    I do have an option for you as we carry axles with the exact dimensions you provided, that being said these axles all have either a 2,000 lb (BT8) or 2,200 lb (BTR) spindle with no brake flange which is common for these dimensions. The Dexter Trailer Axle Beam part # T20BTR-7258 for 2,000 lb or part # T20BTR-EZ-7258 for 2,200 lb are what I recommend. If you need a brake mounting flange then one would have to be added using the Brake Mounting Flange part # 4-34. I have attached a full list...

  • Replacement Axle with Hydraulic Drum Brakes on a 2,200 Lb Boat Trailer
    I have the perfect replacment trailer axle for your boat trailer. For this, I recommend using the Dexter Trailer Axle part # T20BTR-7258. The Dexter trailer axle measures 72" from the face of each hub and 58" from the center of each spring seat. The measurements you gave are likely the same as what is listed above because the start of each measurement could vary slightly from person to person. The outside diameter of this trailer axle is 1.75" which should be what is on your trailer now....

  • Can Trailer Idler Hub Assembly for 5,200 lb Axle be Used for Custom Axle
    You can use the Trailer Idler Hub Assembly for 5,200 lb Axles # 52655IEU on a custom built axle if you like. Most axles that are 72 inches from hub face to hub face are only rated for 2,000 lbs like the Dexter Axle Beam # T20BTR-7258 so this hub assembly would be a great option. You'll just need an appropriately rated (5,200 lb) axle tube so you can weld this unit on, though that is something you would have to source locally, maybe via a custom fabricator to get the length you need.

    There is a way to make a 72" 2000lb axle overslung (axle underneath springs) but they are not sold that way. First you will need an axle. I recommend the Dexter Trailer Axle Beam with Standard Spindles - 72" Long - 2,000 lbs # T20BTR-7258 which has the 72" hub face to hub face measurement you are needing. Next you will need to remove the pre-installed spring seats and have the # TRSS175 welded in the correct location on the other side of the axle in the correct location to match your...

    The bearings that will match your measurements will be the # LM11949 (.750") and the # 25580 (1.750"). With that being said, we do not have a hub that will match those sizes. They are also not a combination I have heard of, so this may be a case of an older trailer using something that is not used anymore. Unfortunately this does happen fairly often and the only real way to fix it, is to replace the axle. The Dexter Axle # T20BTR-7258 will have a 2,000 pound capacity and will measure 72...
