Features to know about

Smooth, Controlled Towing: 89" Round Axle Keeps Tires Tracking Even

A trailer that wanders or bounces can make every mile feel rough. This 89" long round axle is built for steady, straight-line towing with a precision camber bend that keeps your tires flat on the road. The 3,500 lb weight capacity matches common light-duty setups, giving you balanced load distribution and smooth acceleration. The 74" spring-center spacing keeps your suspension geometry right where it should be for confident towing.

Ready to Roll: Pre-Greased Idler Hubs with 5 on 4-1/2" Bolt Pattern

Skip the messy bearing packing. This axle includes cast iron idler hubs that are already pre-greased and fully assembled with bearings, races, seals, and lug nuts. The 5 on 4-1/2" bolt pattern fits a wide range of 13" to 15" wheels, so you can bolt up and go. Straight Easy Grease spindles with built-in grease zerks make future maintenance quick and clean.

Built to Last: High-Strength 2-3/8" Steel Tube and Strong Welds

The axle beam is made from high-strength steel with precision-welded spindles and spring seats. Each weld is 40% stronger than standard processes to prevent spindle failure and hold up to heavy use. The 2-3/8" diameter round tube resists flexing and fatigue, keeping your suspension tight and your alignment true mile after mile.

Low, Easy Loading: Underslung Design for Leaf Springs

Loading shouldn’t be a fight against gravity. The underslung spring seat setup lets your leaf springs mount below the axle for a lower deck height. That means easier loading and unloading for gear or equipment without sacrificing stability. If you ever need more clearance, it can also be flipped using an over-under conversion kit.

Reliable and Certified: Tested and Supported for Everyday Use

This axle and hub assembly meets CSA, QAI, and SAE-N standards for safety and quality. Every component is built for real-world performance and tested under load to ensure even tread wear and dependable tracking. It’s backed by a limited lifetime warranty and lifetime technical support from etrailer, so you can tow with confidence knowing your setup is proven and supported.

You guys are the greatest. Super to deal with. I repair a few trailers so we will be doing business in the future. Thanks again and happy new year



by:

First axle came and was only 65" long. The axle was mislabeled during manufacturing and had a tag on the packaging for the axle I ordered 89" long. I immediately called etrailer customer service and they overnighted me the correct replacement. Correct axle was of good quality but the customer service at etrailer is top notch.



by:

Etrailer made it easy to find the direct replacement for one of my axles on my trailer. Took me about 30 minutes from start to finish to take my old one off and put this new one on.

  • Does etrailer Still Sell Trailer Axles
    Hey Jason, thanks for reaching out! We definitely do still carry trailer axles! I'm linking our selection for you to filter through but if you can give me some details about what you're needing (weight rating, hub-face, and spring-center measurements) I'd be more than happy to help you narrow down what you're looking for to get your trailer up and running!

  • Do You Have a Trailer Axle Rated for 3,500 Pounds, 82 1/2" Hub Face and 75" Spring Center?
    Aloha Albert, I am sorry to hear that you have 2 bad spindles. Swapping out your axle is definitely going to be your best bet. Based on your measurements of 82 1/8" hub face, and 75" spring center, I am not seeing that we have one that fits your needs. The closest thing we have is the one you were looking at the Trailer Axle with Idler Hubs - 5 on 4-1/2 Bolt Pattern - 89" Long - 3,500 lbs # e65GR which is an 89" Hub face. I attached a help article if you want to double check your measurements....

  • Is There An Axle With 89" Hub Face Measurement And 70" Spring Center Measurement?
    Hello Chris, yes as of now the only exact fit is the Dexter Boat Trailer Axle # DX47HR. That is a pretty specific hub face and spring center size that is not very common, unfortunately. The more common setup has 74" spring center measurement like with the Trailer Axle with Idler Hubs - 5 on 4-1/2 Bolt Pattern - 89" Long - 3,500 lbs # e65GR. If you bought this idler hub, you could have a trailer shop or good welder replace the spring brackets and move them to the 70" measurement to match...

  • Are There 72 Inch 3,500 lb Axles
    Hi Bill, You can get a 6 foot (72 inch) long axle, though not one rated for 3,500 lbs; the max capacity for that length is the 2,200 lb Dexter Trailer Idler Axle w/ Hubs # 20545I-EZ-72-10. The shortest 3,500 lb axle is the 89 inch Trailer Axle With Idler Hubs # e65GR. There is a different option which doesn't require any specific length which I also wanted to mention, which is the Timbren Axle-Less Suspension # ASR3500S05. These are a standard height but there is also one with a 4" drop...

  • Replacement Options For A Dexter 3K8874 Trailer Axle On A Utility Trailer
    Hey John, From what I can find the Dexter 3K8874 has a 88" hubface and 74.5" spring center. The Trailer Axle with Idler Hubs # e65GR has an 89" hubface and 74" spring center so it would sit about 1/4" which would likely give you issues trying to line up the leaf springs with the hangers and have the wheels sit out an extra 1/2" so you could run into clearance issues with the fenders. You could technically make it work but I wouldn't recommend it when you can just order exactly what you...

  • Replacement For Mobile Home Axle on Trailer
    Hey Chris, I'll just be straight here - you'll need a replacement axle. While that's not enough info to determine bearings (that actually requires specific measurements at three different locations on your spindle down to the thousandth of an inch), it was enough to determine a new axle is necessary. There are a couple things that give it away, which are the type and size of wheels, as well as how you described them. Those are for a mobile home, and mobile home axles are a one-time use....

  • Are Spindles of Trailer Axles Replaceable
    Hey Jay, you can replace the spindle on an axle but you would need to find a welder who has the correct jigs to do this as you really have to make sure it's installed in correct location to ensure you don't have alignment issues. To pick out correct replacement spindle I would need to know the axle capacity. To pick out correct axle you need to know the capacity as well as the distance between spring seat centers and also the distance from hub face to hub face.

  • Option For Replacing Axle On Older Trailer 89-3/4" HF 75-1/4" SC
    Hello Gabriel. We do have an axle that is very close to your specifications, the Trailer Axle Beam with Easy Grease Spindles # e38GR. This is a 3,500 lb capacity axle. Hub to hub it measures 89" so it is just slightly shorter. This axle has spring seats pre-welded at 74", so those will need to be removed and relocated to 75-1/4". Also please make sure the 3/4" length difference will not cause the tires to sit too close to the trailer frame. Note that this is a round tube axle and it looks...

  • Will Adding a 2ND Axle to a Boat Trailer Increase The Tread Life Of The Tires?
    Honestly Karl, adding a 2nd axle to your boat trailer is not going to increase your tire life enough to justify all the costs needed to add an Axle # e65GR, new Hanger Kit # APT9, 4 Leaf Springs # e54SR plus the cost of the additional wheels and tires. And while the tires may last longer you are going to have 4 on the ground wearing instead of 2 so the tires would have to last over twice as long to make sense. I would start by checking to see if you can switch to Radial tires which tend...

  • Recommended Replacement Axle for a Camper Trailer
    Hey Brian, to go with a longer axle setup you can use the Trailer Axle with Idler Hubs # e65GR. This axle has a 5 bolt pattern, an 89" hub face measurement, but a 74" spring seat measurement. Since your spring seats are at 55" you'd need to cut off these ones and re-weld them at 55" to match your spring seats. What kind of trailer do you have? Also, If there is anything else you need help with, please feel free to let me know!

  • Replacement 3,500LB Axle and Leaf Springs For Vintage Trailer With Flattened Leaf Springs
    First I think you need to address the axle portion of your trailer since you have a fabricated lift block on a drop spindle axle. That axle likely is only rated for 2,000-2,500lbs by the look of it. By switching to a Straight Trailer Axle with Idler Hubs # e65GR you will be able to get rid of the blocks and those extremely long u bolts. This axle is also rated for 3,500lbs with a hub face to hub face length of 89" and spring center to spring center of 74". If your trailer has different...

  • Wider Axle Options For a Harbor Freight 4 x 8 Folding Trailer Which Allow For Larger Wheels & Tires
    Our narrowest 3,500lb axle is going to be the Axle # e65GR which is 89" from hub face to hub face. To mount this and widen your trailer you will need to modify the trailer which will entail new frame and suspension components. We do have a 72" wide 2,000lb Axle # e37YR which still exceeds the weight rating on your Harbor Freight trailer. This will still likely require some modification as it is about a foot wider than your stock axle. Both axles come with 5 on 4-1/2" idler hubs and will...

    While we do carry a replacement for your LM48548 bearing, listed as part # LM48548 on our site, none of our hubs use this bearing and from what I'm seeing your bearing combination is for very old trailer axles. I recommend swapping out your axle to something more current that you'll be able to easily find service parts for, like bearings. To choose the correct replacement axle we'll need to find out the weight rating of your current axle as well as the spring-center and hub-face dimensions. For...

  • How to Change Spring Center on e65GR Trailer Axle
    In order to change the spring center on the Trailer Axle with Idler Hubs # e65GR you will need to cut off the existing spring seats. Once they have been removed, you will need to have # TRSS238 welded on to match your 72" measurement. If you have some kind of adjustable bracket I do not recommend using it. There should be no way for the leaf springs to move horizontally along the axle aside from moving the spring seat.

    While we do have a closer option for you than the etrailer Axle # e65GR, the axle has a higher weight capacity than you need. That is the Dexter Axle Beam - 5,200 # 8327816. With this axle, if you want to use idler hubs, that is the # 008-213-9B. When using these 5,200 pound parts, I recommend checking with the trailer manufacturer to confirm whether the rest of your trailer can withstand 5,200 pounds of weight. If your trailer is constructed for less weight capacity, you will be limited...

  • How to Find Replacement Axle for Hurricane HUR 2178 Boat Trailer
    Finding a replacement axle will require measuring your current axle. Specifically, the hub face to hub face measurement. I would say based on the GVWR it is a 3,500 lb axle. It could possibly be a 3,000 lb axle depending on what they figured for tongue weight, but that would be obsolete so you're looking at 3,500 lbs either way. We only have two length options for 3,500 lb axles so I'll list them below. If you switch from a 3k axle you will also need new hubs. You can choose from the following:...

Once you have the capacity, measure from hub face to hub face to get the axle length. I have attached a video below which shows...
