Specs:
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 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.
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.
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.

Axle fit perfectly. Delivered quickly. And after a year it is still working great.
Awesome, I will never buy an axle from anyone else. I will also tell my friends.
5 stars for looks, apparent quality, and ease of assembly. My only complaint is the axle came with the zert fittings installed on the ends of the axles. This is convenient, but both were non functional upon arrival. One was slightly damaged, and both had the rubber protective material jammed in the grease fitting that I couldn’t remove. I had 2 extra zert fittings in the shop, so quick change and no problem. Maybe these could be shipped uninstalled?
Other than the small, minor complaint, the axle and hubs look great.
I got the axle but not the hubs

Great service. I live in Hawaii, so it took a little longer to get my order, but etrailer kept me updated and were super helpful
Needed it for an old boat trailer and everything fit perfectly
Arrived on time. Good quality and price.
I just got it today have not had a chance to install it yet would like to know if the hubs come with it it shows with hubs was just wondering if they coming separately
Great people to work with. Informative and very helpful.Just a phone call and three days later I have the parts needed to get me running. Excellent service and staff.
The axle worked great after I returned the one that didn't fit. The mechanic had it fixed in 30 minutes.
Items received in a timely manner and were of good quality and fit like they were supposed to.
Quickly delivered and exactly what I asked for!
Shipped same day. Not assembled though. Would have like the hubs pre-assembled to the axle.
