Features to know about
Smooth, Steady Towing Every Time: 3,500-lb Dexter Axle Handles the Load
A trailer that tracks straight and quiet makes every haul easier. This Dexter axle is built from high-strength steel and rated for 3,500 lbs, giving you steady, controlled towing without bounce or sway. The slight upward bend in the beam sets the right camber so your tires stay flat on the road under load, improving traction and wear. It’s a dependable foundation for smooth, in-line performance mile after mile.
Ready to Roll Out of the Box: Idler Hubs and Bearings Already Installed
No need to hunt for matching parts — this axle comes complete with cast-iron idler hubs, bearings, races, seals, grease caps, wheel studs, lug nuts, and marine-grade wheel bearing grease. The 5 on 4-1/2" bolt pattern fits 13"–17-1/2" wheels, so it’s simple to bolt up and go. With the spindles and spring seats welded in place, you can drop it in and be confident everything is aligned and ready to haul.
Built Low for Easy Loading: Underslung Leaf-Spring Design
This axle’s underslung setup — with the 2-3/8"-diameter beam’s spring seats welded to the underside — keeps the trailer riding low and level. The lower deck height makes loading and unloading easier while maintaining solid road manners. Straight spindles with no drop mean consistent ground clearance and stable handling across every trip.
Precise Fit and Proven Dimensions: 89" Hub Face, 74" Spring Center
Getting the right fit matters for alignment and tire life. This axle measures 89" from hub face to hub face and 74" from spring center to spring center — the most accurate way to size a standard beam axle. Welded-on spring seats and a 4-bolt brake flange configuration give you a solid base that’s ready for your suspension setup.
Durable from Core to Hub: Quality Components that Last
From its high-strength steel tubing to the sturdy cast-iron hubs, every part of this Dexter axle is made to hold up under real-world use. The sealed bearings — inner L68149 and outer L44649 — and matching races and seals keep everything turning smoothly. It’s a simple, tough assembly built for the miles ahead.

Weight and Capacity
- Weight capacity: 3,500 lbs
Dimensions
- Hub-face-to-hub-face length: 89"
- Spring-center-to-spring-center length: 74"
- Flange-to-flange length: 82-5/8"
- Tubing outer diameter: 2-3/8"
- A — 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).

- C — The flange-to-flange (C) length: Is measured from the outside of one brake flange to the outside of the one opposite. This length may be easy to obtain if you are replacing an axle, but it's important to note that this measurement is not the preferred method for determining which axle will best fit your trailer.

Prompt delivery. Shipment was well protected from in transit damage.The axle fit my trailer perfectly and the u-bolts I ordered with the axle fit as they were supposed to. My wheels were old with a slightly larger bolt circle than the new hubs. Before I abrasive saw cut the old u-bolts, I tried the new hubs with the old wheels and they did not match up. I had to get new tire and wheels with the 4.5 bolt circle mounting holes. Not a big deal as I needed to replace the ties anyway. But testing the old wheels with the new hubs before cutting the the old u-bolts meant I didn't have downtime on the trailer while waiting for the new wheels and tires. The whole changeover, removing the old axle, installing the new axle, and mounting the tires took me about 3 hours at a leisurely pace.

Direct replacement axle for an older Big Tex landscape trailer I own. Make sure you understand what measurements you need to take from your old axle before ordering. Installed easily, all required parts where in the box (including grease and lug nuts). Also purchased the U-bolt kit.

Great axle. Very pleased with it. I was shipped the wrong axle butt etrailer sent the correct one and I was able to ship the wrong one back later. Got me on the road a little quicker.
Other than that mishap,Ian pleased with the axle and would consider buying from etrailer in the future.

- Converting 3,500 lb Torsion Axle to Spring Leaf Axle on Boat TrailerHey Sam; thanks for the question and yes it is possible to go from a 3,500 lb torsion axle to a spring leaf axle on your boat trailer. You'll need to have new hangers welded on, as well as get leaf springs and, of course, the axle itself. For the hanger kit you can go with the Single-Axle Trailer Hanger Kit for Double-Eye Springs - 3-1/4" Front, 1-1/4" Rear # APS4 which gives you 5 inches of distance between the center of the axle and the trailer frame. For 3,500 lb leaf springs you can...
view full answer... - Identifying the Axle from a Home-Built TrailerThere are a couple ways to determine what kind of axle you have. If there aren't any part markings on the axle or anywhere else on the trailer frame that list your trailer axle specifications, you need to measure your spindle with a calipers to get a precise measurement. I couldn't find a matching bearing based on the measurements you provided, so make sure you are using the right equipment to take these spindle measurements. You can also measure the axle diameter to get an idea of the...

- How Much Upward Bend Should Trailer Axle HaveWhile trailer axles do feature an upward bend like you are describing, there isn't a particular amount/measurement that is standard across the board. This bend in the axle is designed so that it will straighten under a trailer's loaded capacity. While I can't really say for sure if the bend you measured at the rear on your trailer is normal or not, the damage that it is causing to the frame is certainly cause for concern. This either indicates that there is indeed too much of a bend or...
view full answer... - Should Utility Trailer use Mobile Home AxlesFirst, the most important thing I can tell you is that mobile home axles are made for one time use and should not be used on utility trailers; for that you would need an axle designed for use on RVs and to choose the correct replacement axle for your trailer you will need to know the dimensions of your current axle's hub face to hub face and spring center to spring center as in the diagram I have added; the other thing you need to know is the weight capacity of the axle you need, which...

- Parts Needed to Add Second Axle to a Boat Trailer Hey Craig! We don't have an axle that is going to match those dimensions. There isn't a kit that'll convert your trailer to a tandem axle either. To add a second axle to your trailer, apart from the axle you'll need a set of hangers that have to be welded on, leaf springs, U-bolts, a pair of equalizers, shackle straps, and shackle bolts. You'll have to measure your hangers for matching ones and reposition your current axle as well. You're going to want a kit like the Tandem-Axle Trailer...
view full answer... - Replacement Needed for the Titan Hub T1721400042I have a potential alternate option, but unfortunately, the Titan Trailer Hub Assembly for 2,500-lb Axles - 5 on 4-1/2 - Cast T1721400042 is no longer available from the manufacturer. As this uses an uncommon combination of inner and outer bearings, I recommend replacing the axle with a more common set up. With that said, the Dexter Trailer Axle with Idler Hubs - 5 on 4-1/2 Bolt Pattern - 89" Long - 3,500 lbs # 35545I-ST-89 will come with idler hubs and includes all bearings, seals, caps,...

However, there will not be a hub that uses both an inner and outer bearing of this size. With that said, I highly recommend replacing your axles with something that will use a more common bearing combo. Doing this will require a few things. If you look at the Dexter Trailer Axle with Idler Hubs # 35545I-ST-89, it will have a hub face to hub face measurement of 89 inches and a center of one spring seat to the center of the other...

I've added a link to our selection of axles for you to take a look at.

- Can I Use the Dexter 3500-lbs Axle with Overslung SuspensionYes. The Dexter Trailer Axle with Idler Hubs - 5 on 4-1/2 Bolt Pattern - 89" Long - 3,500 lbs # 35545I-ST-89 will work with a trailer that has moved the leaf spring suspension to over the axles. Typically an axle has a slight bend in it because of the weight that it's going to bear, and will flatten out completely and be level to the ground. This won't affect the suspension that can be used with it. I've linked our entire selection of 3500-lbs axles for you to have a look at as well in...
view full answer... - Can Brakes be Added to Second Axle in Tandem Axle SetupYou can definitely add brakes to an axle without purchasing another one. The easiest thing is if your axle already has a brake mounting flange installed on it. If your axle doesn't then you can have one welded on, but we typically recommend replacing the axle in this case just because you can have the peace of mind that the flange was done professionally. I am attaching a link to some helpful articles on adding different types of brakes to an axle that you can check out. I am also attaching...

- Measuring for Replacement Dexter Axle From your photo, it looks like you have a Dexter axle, part number 51955. From my research, it appears this is likely a 3,500-lb axle. However, the weight capacity should be listed on the axle itself, so it would be best to confirm this before purchasing a replacement. You'll also need to know the axle length. I've attached a photo showing where to measure your axle for the correct length. I've also included a link to our axle product listings. Once you know your measurements, you can...

view full answer... - Picking Out Leaf Springs for Triton LXT Aluminum PWC TrailerWhen replacing trailer leaf springs we strongly recommend you replace them in pairs. I would urge you to get a set of matching properly rated springs for your trailer instead of just replacing one. If you look on the frame of your trailer there should be a plate with the trailer VIN number and the axle capacities of the trailer. You will want to pick leaf springs that are as close to the axle capacity as possible. You will want to also measure the distance from eye to eye of your old...
view full answer... - How to Choose an Axle to Replace Torsion Axle on a 1999 Bantam Travel TrailerI do have a way for you to measure for an axle on your 1999 Bantam trailer. The hub-face measurement (A) would be the same as what you have now and the spring-center measurement (B) is taken from the center of one side of your trailer frame to the center of the exact opposite side of the frame. The spring-center is where your leaf springs will be hanging. Since axles like the Dexter # 35545I-ST-89 have the spring seats already welded on it is important to have an accurate spring-center...

- What Info Is Needed to Pick Out Replacement Axle for Jet Ski TrailerWhen picking out trailer axles for a trailer you have to match two dimensions. The distance between the spring center so that it can bolt up to hardware on trailer and the distance from hub face to hub face so that the length is correct overall where the wheels will be placed. With the trailer axle # 35545I-ST-89 that you referenced your trailer would need to have 74 inches between the spring seats and 89 inches from hub face to hub face.
view full answer... - How to Find the Length of a 3,500 lbs Dexter Torsion AxleI just want to make sure when you say track measurement, you mean the center to center distance between the tires. Another industry term for this measurement is the Hub Face measurement. The best way is to measure from tip-of-spindle to tip-of-spindle and subtract 4-3/8" and that will give you the hub face measurement on Dexter torsion axles. Another way is to measure the brake flanges outside to outside and add 6-3/4" and that will give you the results.
view full answer... - Trailstar Trailer Axle is Bent Causing Tires to Wear QuicklyThe problem may not be your axle at all. Is it bent upwards or downwards towards the ground? If it is upwards then that is normal but down means it does need to be replaced. The reason axles have an upward arc to them is so that when a load is placed on them they straighten out and your tires run evenly. When the inside of the tread on your tires wears on the inside that is a good indication that you are overloading the axle which is causing it to bend down too much. Try checking the...
view full answer... - Should an Old Boat Trailer Axle be Replaced if the Seal was Attached in an Odd WayFrom what you described about how the parts were installed on the axle, I highly recommend replacing the axle. This will also go for the hubs. It sounds like everything was made to be permanently sealed on the spindle, which is definitely not suggested. To get a replacement, we will have a few options available. First will be a standard style axle that will span the width of the trailer. The Dexter # 35545I-ST-89 will measure 89 inches from hub face to hub face, and 74 inches from center...

- Single Axle Hay Dolly Axle Upgrade with 1.375 Inner and 1.250 Outer Bearings on a Mobile Home AxleThe only recommendation I could make for you would be to install new axles on your trailer.

Attached is a page that has all of the axles we have with the correct hubs included. You will want to determine which will suit your trailer based on the overall length axle you want from hub face to hub face, then select the distance between...
