Axle Dimensions
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.
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.
Dexters
Dexters 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.
Determining the Bolt Pattern
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.
- If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
- If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
- If D = 3", then the bolt pattern is 5 on 5"
- If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

OK. Finally finished my trailer mod today and installed this axle, idler hubs and springs. Noah was very helpful in sending me a missing wheel bearing from one of the idler hub kits. I am very pleased with the products I received. The only negative comment I have is I wish there had been written detailed instructions with each of the components. In particular the axle is the ez-lube type which I was not familiar with. Especially the item that is used instead of a cotter key on the axle nuts. I could not find any information on this but I'm pretty sure I figured out how to install this locks. I guess I could have called back again and asked for help but I amused to being able to figure things out for myself.

Looks great on unfinished trailer.
Can't wait to finish up.

This axle is exactly what I needed for my trailer. It was shipped and delivered fast. All of the hardware was included as described. It is a very good quality axle. Customer service was very helpful and friendly.

All is in good condition

The product I received was exactly as described on the website. I was very pleased with prompt shipping. The quality of the axle, hubs and bearings seem to be very good. Perfect for an old homemade trailer.

All the parts I ordered fit and worked great. Got my trailer back on the road in no time!

Well made, less than 48 hour delivery!
by: Craig09/08/2023
These axles work great. I replaced three axles on my trailer last fall (2022) with these axles. I was able to install the new axles and springs in about 3 hours because everything matched up very nicely - thanks to the help of the folks at etrailer.
by: Carl09/02/2020
After years of hauling firewood my Harbor Freight Trailer Axle fatigued and cracked. The Dexter Axle from etrailer got me back on the trail. Welded leaf spring seats on the opposite side of the axle at a spacing of 46.5 inches. The wheels stick out an additional 3/4 inch per side. The trailer now rides like a Cadillac. Very excited about putting my faithful trailer back in service, with a serious axle underneath that I have confidence in. The folks at etrailer very helpful and responsive. Thanks

I purchased a number of products from etrailer and I am very pleased with them all. The shipper lost my axle. When I contacted etrailer customer service, they handled my problem quickly and I had a replacement axle in a couple days. Well done!
The products were all of high quality and the assemble was much easier as a result. I have attached a few pictures of the build for those interested.
Thanks etrailer for your great products and service!!
by: Tom 07/17/2023
I installed the Dexter axle on my trailer yesterday, and I was very impressed with the quality and the ease of installation. The install took much less time than expected, and this was helped by the hubs having the bearing pre-installed, what a bonus! This is a great solution to replace a fried axle, I highly recommend it.
by: Jesse06/07/2022
Fits as it should. EZ lube hubs are much easier than having to repack the bearings. This is the second purchase I’ve made from etrailer and their service has been great.
by: Hatch09/11/2023
Solid axle with all the bolts and brackets to mount the axle quick and easy. Solid axle, should last a long time.
by: Richard05/24/2018
I ordered this axle as a replacement for the one on my 1996 Haulin' 4x8 utility trailer. I'd neglected to maintain the bearings and when one went it destroyed my axle. This axle was an exact fit but the spring seats needed to be moved to the top of the axle. I ordered new seats and U-bolt mounting kit as well as the axle. I found a welder to remove the original spring seats and weld the new ones to match my application. Installation was a snap, I just followed the video included on the web site. Ordering my parts from etrailer really saved me $$ over the quotes I'd received from local shops.
by: Kirby L11/13/2016
I bought a axle, springs wheels, hubs etc. to build a utility trailer, I inadvertently had ordered incompatible hubs for the selected axle the person filling the order noticed this and contacted customer service to alert them of the issue who then called me to correct the problem. This saved me the time and expense of returning the part and delaying the project. great service, attentive, knowledgeable employees and great products.
Thanks E trailer.

Used it on a homebuilt trailer worked great and tracks perfectly.
by: Rob L.09/13/2018
Quick delivery with tracking link! Great product and price!! Easy process to install axle and hubs. I would have appreciated a torque specification for the U-Bolts and Lug nuts in the video. I didn't take the time to search other locations or Q&A.
Tip: 1-1/2 " PVC makes a great tool to seat the grease seals. I used my 28MM socket, it was very close to size. I decided to use 2" Schedule 40 PVC pipe to install the E-Z Lube dust seal. I have many tools however no wooden hammers.
by: Gilby08/08/2023
Product was top notch and customer service was even better. Was missing a bolt from package; it was overnight shipped at no cost to me. Will always do business from etrailer
by: Steve06/01/2020
Product seems to be built well. I was missing a set of outer bearings that I had to get from a local tractor supply due to time constraints. They were missing when shipped to me. I have been happy so far with this product as I have pulled my home built teaardrop on it. I have traveled over 3k miles with it as well as a tire set I purchased from etrailer.

Good sturdy wheels and tires and they look good in person.
by: Honest Ed04/30/2016
Really good solid axle... I needed the mounting tabs moved and had a metal fabricator do the work for $20.00. This was used on an old boat trailer that I turned into a utility trailer. Also swapped out the springs with ones purchased from etrailer too. To complete the package I ordered (3) 165/65-8 trailer tires. The trailer tows straight and hauls everything I've ever needed to.
by: Ronald 10/14/2023
Highly impressed with the entire experience. From product selection to the almost immediate order prep and detailed shipping progress and tracking. It gives me hope for American companies. Great job keep it up!
by: Brian06/05/2018
I think I'd like to change the review to 3 stars and say:
Though the mechanical quality of the axle/hubs is great, whatever the axle and hubs are painted with comes off very easily. Simply removing tape would pull the paint with it. This will eventually lead to these parts rusting and you'll need to add an additional coat of paint to prevent rust. The paint quality is very poor
by: Lloyd05/26/2023
I gave a 2 because my complete order was not delivered. I ordered a complete axle for my trailer, but only the hubs were shipped. I had to call and find out what happened and the representative said they didn’t know why it wasn’t shipped but she would make sure it would be completed.
by: Rodney 09/22/2023
The procduct I have bought fell right into place and they protected the parts great and I'll recommend to anyone who needs trailer parts.

- Determining Which Replacement Axle Fits 2000ish Trailstar TrailerI would be happy to help you determine the correct replacement axle for your 2000 Bass Tracker Pro Team 175 and Trailstar trailer but the axle length is actually measured hub face to hub face so you will want to put your hubs back on temporarily and measure from there. In addition you will need to measure from spring center to spring center, and determine the axle rating of your axle. If the axle tag is still on the center of the axle it will have your axle rating on it, or if not you...

- Availability of Complete 72-Inch Axle Kit with Electric Brakes and 4-on-4 HubsWe do offer some complete axle/hub/brake kits such as # 35545E-ST-89 from Dexter, but we do not have a complete kit with the exact combination of features you require. We do offer 72-inch axles with 58-inch spring seats and idler hubs in your 4-on-4 bolt pattern. Part # 20440I-EZ-72 is rated at 2000-lbs and features EZ-Lube spindles. Part # 20440I-ST-72 is also rated at 2000-lbs and has standard spindles. Both kits will work with 12-inch wheels and both come complete with bearings, races...
view full answer... - Spindle Washers for Dexter Trailer Axle with Idler HubsYes, spindle washers are to be used except in a rare occasion where they will not fit. However, the Dexter Trailer Axle with Idler Hubs # 20440I-ST-72 does not come with washer. You will need part # SW1000.
view full answer... - Can Leaf Springs be Mounted Below Trailer Axle # 20440I-ST-72All you have to do to mount the leaf springs to the bottom of trailer axle # 20440I-ST-72 is to weld on new spring seats to the bottom of the axle. This axle has a 1-3/4 inch outer diameter so you would need 2 of spring seat # TRSS175. Welding should be done by a professional welder. Trailer suspension needs about 3 inches of space to travel so if there is not enough space then you would also have to use taller hangers. Dexter does not recommend using the over/under conversion kits with...

- Recommendation For Replacement 2000-Lb Trailer AxleThe best way to find an axle that will match your trailer is to measure the spring-center-to-spring-center distance and the hub-face-to-hub-face distance of the axle you have on your trailer currently. I have attached a drawing that shows where these dimensions are taken. It may be easier to replace the axle with an axle that has the hubs already included. If you find you need a 72-inch axle and your wheels have a 5 on 4-1/2 inch bolt pattern I recommend part # 20545I-ST-72-15. This comes...

- Replacement 2K Idler Axle for Carry-On Trailer Model 5x10GW2KCarry-On steel-mesh trailer model 5x10GW2K uses a 2000-lb-rated idler axle. We have several 72-inch 2K-rated idler axle kits that come complete with hubs, bearings, races, seals, etc. We do not offer 2K axles without hubs. All of these use a leaf spring center spacing of 58-inches. You can see all kits by clicking on the link provided. We have both 4-on-4 and 5-on-4-1/2-inch bolt pattern kits, so just click on your wheel bolt pattern to see suitable options. Since your trailer uses 12-inch...
view full answer... - How To Find The Right Axle/Axle Options For Pop-Up CampersThere are some measurements that you need to take to find out what kind of axle will work with your 1966 Apache Eagle Camp trailer. First measure from one hub face to the other. This is your hub face measurement. The hub face is where the wheel and the hub meet when bolted down. Then measure from the center of one spring hanger to the next. Try to find the axle capacity, usually it is somewhere on the axle but since it is so old, it may be worn off by now. If that is the case get an idea...

- Are Washers Always Needed Between Spindle Nut and Outer BearingSpindle washers aren't always used. We actually sell complete axles with hubs like the # 20440I-ST-72 which does not come with washers. Typically if a washer is needed it will be on a higher capacity hub/axle.

- Recommended Replacement Axles and Leaf Springs for Boat Trailer with Dual 2,000 lb AxlesIf your axles are 60 inches from hub face to hub face and 48 inches from center of spring to spring, then I recommend the Dexter Trailer Axle with Idler Hubs - 5 on 4-1/2 Bolt Pattern - 60" Long - 2,000 lbs # 20545I-ST-60-10 or the 4 bolt hub version # 20440I-ST-60. If you have longer axles with the hub face to hub face measuring 72 inches with spring centers at 58 inches, then you will want # 20440I-ST-72 for 4 bolt hubs. With any of these axles, I recommend the hardware # CE23000. I've...
view full answer... - Recommended Trailer Axle Kit for Fabricating Off-Road Utility TrailerIf you are building your own firewood hauling trailer you might want to consider one of our Timbren axle-less suspension kits. These are available with idler hubs and some also have lifted spindles that can give you better ground clearance (for use in the woods when gathering your firewood). We do have standard beam axle kits too but the Timbrens can be the ideal way to go for fabricators that want an effective but simple installation of their trailer suspension.

When building a trailer you want to make sure that you have the capacity you need for your load compatible with the lowest/weakest component in your system.

view full answer... - Replacement 4 on 4.5 Bolt Pattern Trailer Rim and Radial TireThe tire size ST175/80R13 is pretty standard, so we can definitely get you replacements for the tires. I suggest going with the Taskmaster Provider ST175/80R13 Radial Tire # TTWTRTM1758013C. These are rated up to 1,360 pounds at 50 psi and also has an M speed rating, which means it is rated up to 81 miles per hour. On the other hand, the wheels are proving to be more difficult. The 4 on 4.5 bolt pattern was used on older vehicles and wasn't really ever used for trailers. At least that...
