Loading heavy gear or rolling equipment up onto a trailer can be a pain when the deck sits too high. This axle’s 4" drop design lowers the deck height to make loading and unloading easier and faster. It’s built with an underslung setup where the spring seats are welded to the underside of the 3" diameter axle tube, giving you a steady ride that sits lower to the ground without sacrificing strength.
A trailer that pulls straight and tracks true all comes down to proper geometry. This 94" hub-face-to-hub-face axle is built with a precise bend that creates a zero camber angle so the tires keep full tread contact on the road. That design gives you steady, in-line acceleration and less tire wear over time, whether you’re loaded up or running light.
Braking shouldn’t be complicated or messy. This axle comes with 12-15/16" hub-and-drum assemblies and pre-installed electric brakes rated for 7,000 lbs. There’s no need for an actuator or hydraulic lines—just wire them up and go. It’s an easy, dependable braking setup that’s ready for the road once connected to your trailer’s 7-way.
Packing bearings is one of the messiest jobs in trailer maintenance. The hubs on this axle come pre-greased with bearings, races, seals, and lug nuts already in place. The built-in grease zerks on the spindles make future lubrication simple—just attach your grease gun and top off as needed. That means you spend more time towing and less time in the shop.
This axle is made from high-strength steel with patented spindle welds that are 40% stronger than standard joints. The cast-iron hubs, 8 on 6-1/2" bolt pattern, and 1/2" wheel studs are built for durability on long hauls. It’s CSA, QAI, and SAE-N certified for braking safety and performance, giving you confidence that every stop and mile is backed by solid engineering.

In order to find the correct replacement axle for your trailer there's a few things you need to do. The first one is we need to determine the capacity. The first place I always check for the axle capacity is on the axle tag, which is actually located on the axle. Now, most of these are in the center and they could be a white sticker or they could be a metal plate. Now, not all of them list the axle capacity, but the vast majority do, that's why I look here first. Granted, this is a new axle here, so the tag is in fairly good condition, but we can see on here GAWR, gross axle weight rating, 3,500 pounds, so I know this is a 3,500 pound axle.
So if you do have an axle tag and there isn't a capacity listed on there there may be a serial number, an axle number. And in which case, you could actually reach out to the actual manufacturer with this information and they should be able to give you the capacity. Some of the more common axle manufacturers on the market are Dexter and Lippert. So if you don't have an axle tag, that's okay. There is still other options to determine the capacity.
One would be to take a fabric tape measure and record the circumference of your axle tube. Now, once we have the circumference we can use the appropriate formula to get the diameter. And then using the diameter there's sort of a general axle guideline to determine capacity based on that diameter. So, for example, a 3,500 pound axle is gonna have a 2 3/8 inch diameter beam. Now, a 3 inch diameter beam would represent anywhere from a 5,200 pound to a 7,000 pound axle.
And there's also some larger ones as well as some smaller ones. So if we don't have that axle tag there we could just measure the diameter here of our axle tube. And another way is to actually look at the brake mounting flange bolts. Now, this is just gonna give you a rough ballpark. The 3,500 pound assemblies, they usually use this 4 bolt pattern where it's the larger 5200 to 7,000 pounds, use that 5 bolt pattern.
So that's more of a general guideline. That's certainly not all you wanna do, but it will help you reaffirm when you're measuring. So once we get to capacity there's two more things that we need to gather. The next one is going to be the hub face length. So the hub face length is gonna take our brake hubs into consideration. We're gonna be measuring from the part of the brake hub where our wheel mounts from one side to the other. So we'll go ahead and do that now. Now, once we have our hub face length, we need to determine our spring center length. So the spring center length is gonna be from the center of the leaf spring perch from one side to the other. So once we have all this information we can then use that to select the correct replacement axle for our trailer. We have a ton of different options to choose from based on a few different factors. Number one is the length of our axle, both the hub face and the spring center. There's gonna be several different options for each of these. There's also gonna be different axle capacities based on how heavy you need your trailer axle to be and how heavy your trailer is. Now, we always recommend replacing what's on your trailer with the exact same one that came off. So, for example, if your old axle had an 89 inch hub face that's what we'd recommend replacing it with. And the same goes for the weight capacity, although you can upgrade. No matter what capacity you need we should still have an option for you. Now, in addition to the capacity, we're also gonna have axles with a built-in drop if you need that, or just a straight axle. And we also have some different kits that are gonna come with some different components. We can either purchase the axle, just the spindle only axle. We could get this with an idler hub, or we could get this with an electric brake drum and some electric brakes, depending on what capacity you need..
Ratings & Reviews
Happy with the product, not happy that we paid for a fully dressed axle and it came in parts for us to put together.
Everything I needed came. Already on and working good. Will buy again if needed!!!
Ordered them using my original axel tags, had to have them modified to be mounted correctly and rerun the break wires to fit properly. Not sure if my trailer manufacturer modified the original axels to fit but spent quite a bit to make them work.
This is a big improvement on my existing 3500# axle. I like that the y routed the brake wires through the tube rather than on the outside.
There was no castle nut kit included.
I had to source the parts from another vender to complete the job. Very disappointed
I didn’t think to clarify, I expected this to be shipped as one ready to install assembly. What I received was multiple shipment and not quite all the parts. Customer service quickly resolved the missing items and assembly and install wasn’t terribly difficult so I’m not knocking the product. It is what I was sold.
Awful service. Ordered an axle they sent a hitch. Cancelled order cause they weren’t going send axle out till they picked up the hitch lol. They still haven’t picked up and won’t refund money till ups picks up. Look around I found an axle place close by 30 minutes away with axles in stock. I will never use etrailer again!!!!!
Delivered as described, earlier than expected, less costly than others with free shipping!
Careful measurements and the axle bolted right up.
Fully greased hubs with seals and bearings installed made assembly quick and easy.
Waiting on new tires for the trailer and will road test soon.
Couldn’t be happier with this purchase from Etrailer!
The axle and spring seat are doing well after a year. Even with my shade-tree mechanic welding abilities and thousands of grueling miles thru some of the roughest highways in North America (namely West Virginia) both are holding up to the task.
The axle and brakes were a perfect fit. All of the parts I needed were included and installation was straight forward. I could not be happier.
I ordered two axles to upgrade my trailer capacity to what the frame is rated for, 12,000lbs. The axles have great bearing seats and backing plate studs. The backing plates are fully assembled and ready to connect to the wires already installed into the axle tubes. The hub assembly went smooth and only one set of break shoes needed adjustment. A good buy along with the 5 fully assembled tires and wheels.
Buying the kit complete was a good decision. It showed up early than predicted and having the grease and wires already in place shows your professionalism. I would recommend this product and company to everyone in the market.
Where the leaf spring sits on the axle was off about 1/4 inch had to finagle the axle abit but made it work.
The axles are not yet installed. There was 1 bolt missing I called and they shipped it out immediately. to date everything was as they said. My delivery arrived much sooner than excepted. I would recommend using etrailer they have a very good process.
The entire process was flawless, from purchase to installation.
Super fast shipping and easy install everything went smooth and fit perfect would definitely recommend
Awesome axle the spring brackets where wrong from the description but moved and rewelded to fit with zero problems would definitely buy from this company again
