Axle Dimensions
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.
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.
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.)
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.)
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"

by: Tommy08/05/2022
When I opened the box I was missing the 4 hubs. I called CS 2:30 on a Wednesday and notified them. I was going out of town Friday to fix a trailer. I told Bailey with CS this and she said I will have them by Friday I be darn 10am Friday they were at my door. I am Houston not very close to them. I guess they sent them air. Anyway excellent CS and the parts are quality as well I have ordered from them before Thanks Bailey.

I'm currently installing it to replace a practically good Axle but the Spindle on the original Axle doesn't have Cotter Pins. A friend suggested I change the bearings since the wheel was wobbling but after I changed them, the wheel continued to come off. After watching U-Tube Videos, everyone of them had Cotter Pins, so I decided to be safe rather than sorry and replace the Axle with one of yours plus now ALL the bearings are NEW with New Hubs, WELL WORTH THE MONEY I SPENT.
by: Dennis08/27/2022
Easy ordering, axle arrived on time and no damage. The axle worked perfect for my camping trailer, would recommend your company any time.
by: Jeremy07/15/2022
I purchased two of these axles to replace my old square ones. They appear to be good quality but they arrived damaged. The grease fittings on the ends were smashed because packaging wasn't adequate. I've emailed back and forth and was shipped the wrong parts for replacement. In the end I was told I'd have to cut the spindles off and replace them. All I need is new grease zerks that thread on the ends of the axles. Be prepared to purchase these on your own because customer service is subpar on a remedy and the way they package them for shipping does not prevent damage.

Needed to beef up my little trailer project from a 4 lug to a 5 lug st up.These were perfect, and arrived quickly!
by: Ron05/17/2023
The axle is of great quality, I had to have mine fabricated a bit to match the old spring seats.but I wouldn't hesitate to buy the axle. The shipping and customer service is top notch from etrailer. Excellent products, services and shipping...
by: Michael04/08/2023
Just what I ordered, had to modify to fit my 1720lb Harbor Freight trailer as far as the spring seats. I knew that going in so no big deal. Great help and info from the order person.
Matched it up with bigger tires and etrailer finders!!!
by: Chris10/24/2023
The original axle on my trailer suffered a catastrophic event, making it absolutely unusable. The replacement from etrailer fit like a glove and installed in a very reasonable amount of time. I couldn’t be happier.
by: Steve09/02/2023
Axle worked just as it should. The best things about this company are their selection, speed of processing and communication. The best customer service of any company. Ashley was extremely helpful and quick to answer my questions. Terrific service company
by: Anthony04/03/2023
The axle and hub/bearings were great, very good quality.
Just fyi, regarding the u-bolt kit, 2 of the 4 u-bolts supplied were 3/8 UNC thread and the other 2 were UNF--- but all the nuts were UNF --- fortunately I had some spare UNC nuts on hand. Very pleased with the quality and speedy delivery.
by: Keith 11/02/2023
Perfect fit, was hoping it was made in USA
by: Shanon08/25/2023
I might have measured it wrong, but it still worked fine. I just didn't know where to measure from. My axle was broken, and couldn't get measured good.
by: John 08/06/2023
Good: Excellent service by Lori B. Full order arrived quickly.
Acceptable: Light surface rust on the axle mount. Nothing major. Otherwise five stars.
Would recommend to others.
by: Alfred04/13/2023
Would give it a 5 except one of the grease fittings was damaged in shipping. The axle should be shipped without the grease fittings attached. Shippers stand the axle on end, crushing the fittings on the end.
by: Martin 08/01/2023
Had a shipping problem not etrailers fault they shipped another axle right away very quickly customer friendly for sure
by: Helen08/18/2023
The ordering process was so easy and our questions were answered with great extra information. The to make things even better our order came in 3 days earlier than expected! There is no other site to go to for all your trailer needs.
by: Tony 07/28/2023
I was amazingly impress with how easy it was to install. I'm not mechanically inclined but with the easy access to the trailer axle. I may become a mechanic, (smile) thank you very much for your item and support.

Awesome, I will never buy an axle from anyone else. I will also tell my friends.

Used as an axle on my wood splitter and it is really great. Makes it very easy to move around now.

Fast delivery, well packaged, so the axle wouldn't get damaged during shipping! Would for sure order again, and highly recommend etrailer!

- Availability of 3,500 lb Trailer Axle that is 89 inches Long that Has 4 inch DropThe etrailer axle part # e72GR matches everything you need but you didn't mention the spring seat to spring seat dimension you have which is only piece of the puzzle missing. The spring seat dimension is the attachment point for the axle to the trailer so this has to be exact. This axle has a 74 inch dimension for that and if that matches what you have it would work really well. All of the axles we have that match what you listed have this dimension as 74 inches so if you have something...
view full answer... - Replacement for 5-Lug Bolt Pattern, 89" Long Axle with 4" Drop and 74" Spring CentersYes, if sounds like you're looking for the Trailer Axle with Idler Hubs # e72GR or Trailer Axle w/ Electric Brakes # e95SR for your application. These both match the hub-face and spring-center measurements you referenced, they have the 4" drop, and they also use the standard 5 on 4-1/2" bolt pattern you mentioned. Attached is an installation video of an axle for you to check out!
view full answer... - Recommended In Bed Wiring Harness for a 2023 Chevy Silverado 2500 Yes, there is. You will want the Demco 5th Wheel/Gooseneck 90-Degree Wiring Harness item # DM8555002. This harness puts a 7-way connector in the bed of your 2023 Silverado and allows you to keep the one on your bumper. This makes hooking up to your 5th wheel trailer easier and more convenient. The harness plugs into existing wiring so you don't have to cut into your new trucks factory wiring harness. I have linked an installation video below.
view full answer... - Replacement Axle For a Boat Trailer With a Old Tapered Spindle of 1.5 Inches to 1.25 InchesBased on your spindle tapering from a 1.5" diameter to 1.25" it sounds like a odd sized spindle which is no longer used. If you can provide me with some more information including the weight capacity and axle type on your trailer I can help you select a new axle like the Axle # e72GR. This particular axle has a hub face to hub face measurement of 89", spring center to spring center of 74" and is rated for 3,500lbs of trailer weight.
view full answer... - Are Spring Seats for Dexter E72GR 3500 Lb Axle Available SeparatelyWe do sell the spring seats or perches separately as part # TRSS238 which are sold individually. You can remove the existing spring seats or simply leave them in place if they don't interfere with anything, then weld the new ones where they're needed.
view full answer... - How to Tell if Trailer Axle Will Fit 1987 Ranger TrailerIf your current axle has 89" hub face and 74" spring center measurements then yes, the Trailer Axle with Idler Hubs - 4" Drop - 5 on 4-1/2 Bolt Pattern # e72GR can be used as a replacement but you'll also need to swap out your U-Bolt setup for the CE Smith U-Bolt Kit # CE23002 since you'll be changing from a square axle to a round axle. Attached are some review videos as well as a photo showing where to measure for the hub face and spring center measurements.

- Recommended Replacement for Torsion Axle on Shorelandr Boat TrailerI do have replacement options for you but we don't carry torsion axles which I assume is what you have so the best option we can offer you is an axle-less like system the Timbren Axle-Less Trailer Suspension part # ASR3500S04 which also has a built-in drop like your existing. It has a 3,500 lb weight capacity but there's several other variations if this isn't what you need, just check the list below. These systems are great because they provide much better ground clearance and ride quality...
view full answer... - Replacement Axle-Less Suspension for a Boat Trailer I have a solution for you but we don't have any axles with a 92" length. Instead I recommend using the Timbren Axle-Less Trailer Suspension item # ASR3500S05. This axle-less suspension system will attach directly to your boat trailer's frame. It has a 3,500 lbs capacity.

This has the weight rating, 4" drop, and hub bolt pattern you're looking for and since it installs directly to the trailer frame there aren't any specific hub face or leaf spring measurements it matches with. If you're wanting to stick with the same axle type you currently have then you'll need to reach out to a local trailer shop and have them order a custom one...

Although we do not have square axle replacements, I do have a solution. I recommend the Timbren Axle-Less Trailer Suspension System. Since this system fits any trailer frame width, you will only need to find the capacity of your current axles to find the right replacement. This should be listed on the axle tag. If you are unable to find it on...
view full answer... - 89 inch 3,500 lb Trailer Axle, Suspension and Hangers for Utility TrailerWe do have 89 inch 3,500 lb trailer axles that come with idler hubs like the part # e65GR which is a straight axle or the part # e72GR which is a 4 inch drop axle. Both of these have their spring seats at 74 inches apart on center. Then for a leaf spring the part # e68SR is for a 3,500 lb axle and would work great. For a u-bolt kit to secure the axle to the leaf springs you'd want the part # APUBR-1 and for a single axle hanger kit with everything else needed you'd want the part # APS4. For...

That said, there are only a few other parts needed to complete the task which I have attached below. Single-Axle Trailer Hanger Kit for Double-Eye Springs part # APS1 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles part # e54SR I have also attached for you below a list of wheel/tire options compatible with this axle as well.

I do have a solution, but we do not have an axle that matches this length. What I can offer is the Timbren Axle-Less Trailer Suspension System. This system fits any trailer width and will upgrade and replace your suspension in addition to the axle. If you don't need brakes then you can use the # A35RD545. If you would like an option with brakes then you need the # A35RD545E instead. Both of these...

To go with a standard axle you'll need to measure the hub face to hub face measurement, and spring seat to spring seat measurement (shown in diagram below) to find a compatible axle, but I can tell you from experience you'll almost 100% be ordering a custom axle to get one with the capacities/specs you're looking for to fit your trailer as they tend to come with a much smaller 2,000lb axle.

- Replacement 3,500LB Spindle/Axle Options For Boat Trailer With Obsolete Tapered Spindle 5 on 4-1/2Your spindle is an obsolete size and will need to be replaced. We have a couple options such as our Replacement Weld On Straight Spindle # TRU77FR or the 4" Drop Spindle # TRU87FR both of which are designed to weld onto a 2-3/8" outside diameter axle tube. Then you will be able to use a standard size 3,500LB Idler Hub # AKIHUB-545-35-EZ-K. We also have some axle options if you would rather just get a replacement axle you can bolt on.

It's possible to use a larger hub face like the etrailer 94" Long Axle # e35GR but you need to make sure the 78-1/4" spring center measurement lines up and that the 7K weight rating isn't too much for your application. For slipper springs we don't have anything that matches 26" exactly, but we have the 5-Leaf Slipper Spring # e74SR that is made for a 7K axle and measures 26-5/8" long overall.

You can double check those bearings numbers and that your brakes mount using a 4-bolt pattern to make sure it will be compatible.

The System # ASR1THDS01 places the hub face 6" from the trailer frame and the System # ASR1THDS02 moves the hub face to 8-1/2" from the trailer frame. Both of these systems use a larger spindle for a 3,500lb axle so you will need an Idler Hub # AKIHUB-545-35-EZ-K which has a 5 on 4-1/2" bolt pattern.
