1-3/4" Round Steel Axle: Strong beam built for steady, in-line towing and durability.

Features to know about

Smooth, Steady Tracking on the Road: 72" Hub Face, Zero-Camber Design

A worn or bent axle can cause uneven tire wear and wandering. This 72" hub-face idler axle beam keeps your trailer tracking straight with a built-in bend that maintains a zero-camber angle under load. The design ensures even tread contact across both tires so it tows steady and predictable mile after mile.

Built for Everyday Hauling: 2,000 lb Weight Capacity, 1-3/4" Diameter Steel Beam

When you need dependable strength without extra bulk, this 2,000 lb rated axle delivers. It’s built from high-strength 1-3/4" diameter steel and serves as the backbone of your trailer’s leaf-spring suspension. The solid construction gives you a reliable setup for light-duty loads without flex or fatigue.

Easy Maintenance Between Trips: Straight Easy Grease Spindles

Keeping bearings in good shape is simple thanks to the Easy Grease spindles. Each spindle has a built-in grease zerk that lets you add fresh lubricant directly to the bearings (sold separately) without disassembly. It saves time in the driveway and helps prevent wear before your next haul.

Low Load Height for Quick Access: Underslung Spring Seats Welded to the Underside

Loading gear or equipment is easier when the deck sits lower. With spring seats welded to the underside, this underslung design sets the trailer at a lower ride height that simplifies loading and unloading while maintaining stable handling.

Reliable Construction You Can Trust: Certified Welds and Proper Fitment

Each spindle and spring seat is precision welded using a patented process that’s 40% stronger than standard welds, helping prevent spindle failure under stress. The welded-on spring seats are set at 58" centers for consistent alignment, and the assembly meets CSA, QAI, and SAE-N certification standards for lasting dependability.

JD, that’s a clean setup on your utility trailer. Everything looks like it came together just right. Glad to hear it showed up well packaged and that you’re happy with the quality. That’s exactly what you want when you’re putting something like that into service. What are you usually hauling with that trailer?

WOW! Super fast shipping! Ordered on Saturday. They said it would be here on Friday, it showed up on Wednesday.

by: Kia 04/25/2026

The product is very good, but the method of shipping was terrible. Originally, I ordered this about a month ago and the first one was shipped to me by USPS which I never received. I had to call Amy to re-order another one 2 weeks later. The second one was sent by UPS and I received it within four days. Amy is very helpful.

Great price and good quality. 3500 lbs 4 in 74 in spring ct . Like center grease to rear bearing hole. Packed then removed zerk and then used bearing buddy

by: Jason 05/30/2023 One Year Later

The axles that I ordered last year are still working out great. But even better than the parts was the service I got from etrailer. It was so great working with a company who took the time to listen to my project and help me get the right parts I needed, especially coming right off the heels of a terrible experience dealing with bad information and wrong parts from a competitor. Even with some damages in shipping, the returns/ and replacements were no hassle, with most issues being quickly resolved and not even costing me any additional downtime. As a contractor keeping a small fleet rolling, your competency and professionalism have made me a customer for life!! You guys at etrailer will be my first stop for trailer parts.

Seems like a quality product. Did not come with nuts for the brake retaining studs though. They are 3/8-24 for anyone who needs to know. I couldn't find this info in the description.

Everything is working perfect with that replacement axle. I have definitely put it to the test a lot of miles with a lot of weight. Very highly recommended.

The axle fit great. Just what I ordered. The reason for 4 stars is because the packing did not protect the grease zurc on 1 side. There was a rubber guard that protected 1 side but not the other. Without the cover, the grease zurc was damaged during shipment.

by: Harold 07/29/2025

The threads on one spindle were damaged. One spindle had a rubber cap protecting the spindle threads, but the other side did not. I doubt the damage occurred during shipping since the axle was well wrapped. I was able to get the spindle nut started (after many attempts) and straighten out the threads. Other than thread issue, the new axle fit perfectly.

by: Kevin 01/12/2026

Great customer service quick delivery on orders

by: S 11/30/2023

Welds looked good however the assembler failed to rotationally align the weld on spindle/brake mounts properly. One was about 3 degrees off and the other side was an 9.5 degrees from the 12 oclock position. Not sure about the thickness of the tube. Kind of strange to look at when the top of the brake system is not at 12 oclock. Found this after I removed the spring pads on this 2.1 degree camber axle so I had to jig the tube to fine zero toe to locate the new pads as the 2.1 camber tube changes wheel alignment depending on the bend/ springpad relationship. Not sure the AVG JOE is going to be able to move the spring pads when the brake mounts can't be used as a reliable ref point. If the toe is off from improper pad rotational location. the trailer will eat tires at best or worse cause a loss of controlled tracking and someone could get get killed.

The product seems perfect but both grease fittings on the axle got smashed and transport I have to replace them

by: Juan 08/12/2025

I like it the only reason I not put excellent is because the grease fitting thinks it's damaged

Easy to install, great quality and has performed flawless, used it on the front axle of my tandem axle skid loader trailer.

by: Douglas 02/15/2025

This is a quality axle that I will use on my single axle utility trailer. The axle is cambered and has the spring seats mounted. Just install your springs and hubs and you're ready to go! Great product!!!

How to Choose Replacement Axle for Lowe's 5x8 Trailer
I'd be more than happy to help you out! If you can measure the hub-face and spring-center measurements of your current axle that will help me know what you're needing. For example, the etrailer Trailer Axle with Idler Hubs # e65GR has a hub-face measurement of 89" and a spring-center measurement of 74" (see attached).

How to Find Replacement Axle for Hammerblow Trailer
Hi Ryan; to find a replacement axle you need to know the capacity as well as the hub face to hub face measurement (which is considered the length). It is also helpful to know the spring seat measurement but the spring seats on a replacement can be cut off and moved if need be. I would check to see if there is an axle tag with the capacity if you aren't 100% sure. I also attached a video below which shows how to measure. Assuming you have a 2k axle we have the following lengths available: -Trailer...

Availability of Replacement Hub for AL-KO 8440
Hi Kevin; I agree and would say that the # AKHD-545-2-EZ-2K will give you the same result. Unfortunately, this seems to be a classic case of AL-KO parts not matching industry standards. AL-KO is no longer around, and many of their axles/spindles/hubs didn't match up with other brands. You might be able to find some old AL-KO parts out there but we don't carry them anymore. The best solution I can offer is complete axle replacement. Since none of our 2k axles have a brake flange the universal...

Can Brake Drum Be Added To etrailer e37YR 2K Axle With Idler Hubs?
Hey there Mohan. The Trailer Axle with Idler Hubs - 5 on 4-1/2 Bolt Pattern - 72" Long - 2,000 lbs # e37YR you were looking at already has an idler hub on it which is not setup for brakes. You would need to replace the axle with something like # e78GR with brake flange welded on # 4-34. Then you can add drum brakes to the setup. Let me know what you're thinking or what exactly you're trying to do and I can dig deeper for you!

Upgrading Axle for 5 on 5 Hub for Carry-On 5X8G Trailer
Hey Ben, welcome back! Are you trying to match the bolt pattern for vehicle wheels? We do carry 5 on 5 hubs like # AKHD-550-35-EZ-K (hub and drum) or # AKIHUB-550-35-EZ-K (idler hub). However, these fit your standard 3,500 lb axle spindle with # L68149 inner and # L44649 outer bearings. An axle like the # e78GR matches your measurements but it is a 2k axle so it won't work with the hubs. I have two possible options for your. The first is to contact a company like Dexter and have them make...

Replacement Axle for a 1990 EZ Loader Boat Trailer
Hey, Matt! We do have an axle that is 72" for the hub face but nothing that is 72.5". All of the axles that are 72" long have a spring center of 58". This 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. etrailer axles part # e78GR is just the axle with no hubs or anything else. If you do need new hubs as well we have part # e37YR...

2,000 lb Trailer Axle with 5 Lug Bolt Pattern that Cab Fit 12 inch Wheel
Hey Vince, the flanges on hubs of the axle part # e37YR are too large in diameter to fit behind a 12 inch wheel. If you went with a Dexter idler hub instead on this axle like the # 8-259-5UC1-EZ it will work since it has a smaller overall diameter. To go that route it would make more sense to get the axle without hubs part # e78GR. These are not made in the USA... We have a similar Dexter axle that is made in the USA part # T20BTR-EZ-7258.

Availability of Replacement 72-1/2" Trailer Axle and Leaf Springs
Hi Brian; what is your axle capacity? I'm not sure what the 4" measurement is either, possibly a 4" lift/drop? The closest thing we have in length is a 72" axle like the # e78GR. This would be 1/4" shorter on each side and has a 2,000 lb capacity. You would also have to cut off the spring seats and weld on # TRSS175 to match your 60" measurement. The only other option we have is a universal system like the # ASR2000S01 which fits any trailer width. For leaf springs, I will once again...

Looking For 3,500 lb Axle For Boat Trailer
Hello Duffy. We do have one axle with the spring seats at 58", part # e78GR although this is a 2,000 lb idler axle, so no brake flanges. All of our 3,500 lb axles will be much longer than you are needing, with spring seats at 74" or 80" and hub face measurements of 89" or 95". So, we really do not have anything that will be close to your specifications. I suggest reaching out directly to an axle manufacturer like Dexter. They have a lot more axle options or they may be able to custom make...

Do You Have a 2,000 lbs Axle w/ a 73" Hub Face?
Hey Jake, thanks for the information. The closest axle I have to those dimensions is the Trailer Idler Axle Beam item # e78GR. This is a 2,000 lbs capacity axle with a 72" hub face. It's got a straight spindle which uses item # L44649 inner and outer bearings. The spring seats are mounted at 58" on center so you'll need to find a welder to install two of the item # TRSS175 at 62" for you. What's your project trailer going to be used for?

How To Measure An Axle To Determine The Correct Replacement
All of our axles are measures across from hub-face to hub-face. I have attached a diagram below showing where we measure the axle from. The diagram shows the Trailer Idler Axle Beam # e78GR. We will look at the hub-face length and the distance between the spring seats when determining fitment of an axle. If you are replacing an old axle we would want to try to get you an identical replacement. It is also good to know the weight capacity of the old axle.

Is There a 3,500 Lb Trailer Axle with 72" Hub Face Length
I do have an option for you but all of our axles within the hub face range you to specified have a weight capacity under 3,500 lbs. The Trailer Axle with Idler Hubs part # e78GR for example has a hub face to hub face measurement of 72" and has a 2,000 lb weight capacity. It does not have brake flanges installed so if you wish to add brakes you'd need to weld these on yourself using the Brake Mounting Flange part # 4-34. You could then complete your setup using the Electric Trailer Brake...

Is There 2,000 lb, 72 Inch Axle With Spring Seats on Top
Nope, you aren't missing anything. There are not any 2k, 72 inch axles with the spring seats on top, just with standard spring seats, like the Trailer Idler Axle Beam # e78GR. What you can do is have new spring seats welded on, which admittedly isn't as easy as just finding an axle with pre-existing spring seats, but it's really the only option. For this use Spring Seat for Typical 2,000-lb, Round Trailer Axles with 1-3/4" Diameter # TRSS175.

Replacement Axle With 72 Inch Hub Face to Hub Face Measurement
We do have a 72 inch hub face to hub face axle, but not one with a 69 inch spring seat to spring seat measurement. That said, what you can do is use the 72 inch axle and have new spring seats welded on where needed. There are two axles with a 72 inch hub face to hub face measurement, one with a 2,000 lb capacity and the other with a 2,200 lb capacity so be sure to get the one with the capacity you need: - 2,000 lbs: Trailer Idler Axle Beam with Easy Grease Spindles # e78GR - 2,200 lbs:...
