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.

Bolt Pattern - Even

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.)

Bolt Pattern - Odd

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.)

Bolt Pattern - Side

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"

Average Customer Rating:  4.8 out of 5 stars   (38 Customer Reviews)

This hub-and-drum assembly fits 3,500-lb axles with #84 spindles. For electric or hydraulic brakes. Inner bearing (L68149) and race, outer bearing (L44649) and race, grease seal, grease cap, wheel bolts, and lug nuts included.


I had a very pleasant experience dealing with etrailer. Their customer service department was exceptionally responsive to ensure that I got my parts on time. Five stars isn't enough


This Drum is Heavy as it should be, but the packaging is terrible. Place the Bearings, Lug Nuts, and Seal all in a light weight bag and expect no Damage? The seal was bent and the bearings have metal shavings / Dust from the Lug Nuts! Of course they can be cleaned, but that is just more work. I have never seen Bearings not individually packaged to keep them clean, and I have been doing bearings for over 50 years. You get what you pay for. Buy elsewhere!


Outer races were installed making the rest of the installation easy. Shipping was fast and on time. Packaging was solid. Great deal for all that was included (drum, bearings, lugs, seal, dust cover). Don't forget you'll need a new cotter pin since that is not included. Only problem I had was that I lost a lug nut.


Nice Product, fit my 1975 Airstream camper perfect! Very pleased with the quality. Arrived in timely manner and well packaged. I will purchase from etrailer again.


As always, great product from a company that built their reputation by getting it done the right way. I highly recommend this company and the products they sell.


Thank you for your expeditious shipment! Arrived quicker than noted. I always try to get OEM replacement parts rather than after market, saves a lot of headaches lol. Will definitely use this company for further trailer parts. Thanks again.

Havent had any issues, working just as expected. Great replacement, have another trailer needing this upgrade.

The hub worked perfectly and we have had no trouble with it. Was very happy with the service

The hub and bearing are working great
Jim G - 05/09/2022


I installed these hubs as part of an upgrade and rebuild of a 20 year old trailer and so far they are working great! I wanted to convert my trailer to 6-bolt wheels to make them standard with my other two trailers and the conversion worked flawlessly!


When I called last year I got a young women on the phone who was very helpful. She explained to me how to check my trailers axle to make sure I purchased the correct parts. When I received the parts everything was perfect. They fit and have been working great for the last year and don't see anything changing. I have made numerous purchases from etrailer and don't see that ever changing. Thanks for the help.


Kathy went far beyond what she had to do, in order to get my company trailers back on the road. She got us the Dexter hub assemblies shipped out promptly and at a great price. We still had to find an axle, bc they were out of stock.. But Kathy directed us to a few other competitors. One of which helped us out with that. Thank you very much.

Weve had nothing but trouble with chinese parts failing, constantly. Never had a problem with Dexter parts tho. BUY DEXTER brand. Or buy 2 or 3 chinese parts as backup. Your choice.


Very happy with product and price. Shipping time was just what I expected. When using the online catalog I was able to pin down the parts that I needed. The one thing that would have been better was that the backing plate bolts didn't come with nuts (7/16 fine). The size is not that common so a trip to the store was required. Overall, very satisfied.


Drums, Bearings, & Brakes arrived promptly within a few days of ordering. I chose the Dexter brand parts for 2 reasons. One because I have owned as well as installed Dexter parts in the past and I am familiar with the quality and craftsmanship. Also, and foremost "Made in the USA". Kinda makes you wonder. Do the Chinese look for the "Made in China" label?
Thank you,
God Bless America!
I'll be back,


Great service before the sale. Karen answered all my questions and helped confirm the hubs would work for my conversion. Fast shipping. Hubs worked as planned...couldn't ask for more. Thanks Karen!


Hubs were in excellent condition. All machined surfaces looks like they just came off of the lathe. Painted surfaces looked to be well done also. Bearings came in a separately packed box inside one of the larger boxes to protect them and they were individually packaged in zip lock bags to keep out moisture.
Shipping only took three (3) days---that's amazing.


The parts arrived quickly and safely. Etrailer answered all my questions when I called and when I wrote by email. The parts are very high quality as well.


Perfect fit for my RV. Only took 30 min to pack wheel bearings with grease and install it.


Exactly what I wanted. Super fast shipping. I will buy from for all my future needs. Keep up the great work!


Everything was PERFECT !!! Order was a day early,Chris W. was the most helpful person I have ever dealt with for on line products. I highly recomend E Trailer. and Chris THANX SO MUCH !!!!!


As always...packaged professionally and received promptly. Very satisfied and will continue to do business with etrailer.


Hub and breaks were delivered quickly and price was great. The items were what I expected and installation was simple. Would highly recommend this company.


Product arrived on time with excellent tracking information and the parts were high quality parts from Dexter Axle that fit like a glove.


Great fit, function, reliability, 5 yr warranty. Dexter is an outstanding brand.


Working well a year later - not like the original (new with trailer - China unlabeled)


Great fit and quality... no problems at all a year later.


Quick shipping, easy to deal with. Correct parts. Thanks

  • Do the Races Come Fully Seated in the Trailer Hub and Drum Assembly # 84656uc3
    I went out to the warehouse and checked our stock of hub and drum # 84656uc3. All of the units are just as you have described and the races are installed correctly. If you are looking at the inner race from the back side of the hub and drum, there will be a small space of smooth metal towards the center of the hub and then a rough patch right in the middle. Take a look at the pictures I have included.

  • Re-Surfacing Specification for Hub/Drum Assembly on 3500-lb Axle
    First, thank you for your recent order from etrailer. Most hub/drum assemblies, including the Dexter # 84656UC3 that you purchased, will indicate their maximum re-bore dimension right on the hub outer surface. Please refer to the photo I have linked for you.

  • Can the Armature Surface of an Electric Drum Brake Hub Be Turned Like the Brake Surface
    The part of a hub/drum assembly that makes contact with the electromagnet, the armature surface, cannot be machined. If the surface is deteriorated you'd do well to replace that hub. The link provided will show you all hub/drum assemblies which you can sort using the filters on the page. Be sure to match your bearing set, bolt pattern and axle weight capacity when choosing a new hub. You might also refer to the linked article on re-packing bearings.

  • Is a Double Lip Seal Included with Trailer Hub and Drum Assembly - 3,500-lb Axles - 6 on 5-1/2

  • Hub and Drum Assembly for 3,500 Pound Axle with 6 on 5-1/2 Bolt Pattern Hub Group 8-250
    The 8-250 hub and drum assemblies are unique in that they feature that 6 on 5-1/2 bolt pattern normally seen on higher capacity hubs. For a replacement you can use # 84656UC3. The bearings, races, and seal are included. You will also get a grease cap and new lug nuts with it. If your trailer has EZ lube axles with the grease fittings at the ends then you would need # 84656UC3-EZ instead. I have linked a couple of videos on these assemblies for you to check out.

  • How To Find Replacement Bearings, Races, And Seals For Lippert Axle
    I did some research and was unable to find the component listing for the hub assembly you referenced. The best way to find out what the components are would be to remove them and locate the numbers on the bearing and seal and race. I have attached a photo that indicates where the part number is normally found. If you cannot find the numbers on the parts, the only real way to find the correct components is to use a digital or dial caliper and measure the spindle you have on your axle....

  • How to Find Correct Trailer Hub
    I can tell you how to determine the correct replacement hub, but we would not have any way of identifying a replacement hub from a photo. So there are a number of things you'll need to know; first, you need to know the weight rating of your axle, and also what bearings your current hub has. You will need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them.

  • Solution for Replacing 14 inch Trailer Wheels with 15 inch for Higher Weight Capacity
    Probably your simplest solution would be to replace your hub/drums on your Dexter 3,500 axle with ones that have a 6 on 5-1/2 inch bolt pattern like the part # 84656UC3-EZ which you'll have a much easier time finding higher capacity wheel and tire options for like with the # LHAW124 which has a tire size of ST225/75R15 and a weight capacity of 2,830-lb max load at 80 psi and comes with 1 year roadside warranty.

  • Hub and Drum Recommendation for a 3,500 Dexter Axle
    First off thank you for all of the information you listed, that makes picking out a replacement hub much easier. Most likely you have the number 84 spindle as the dimensions you gave are pretty close to what that spindle has. You will need to double check your measurements though for the inner bearing as that should be 1.38 inches and not 1.475. If that all checks out the correct hub and drum you would need is the part # 84656UC3-EZ. It has the bolt pattern you need, the capacity you...

The "LC170-T" that you provided is not a valid serial number. The serial number will start with either a "V" or "NV".

  • How to Determine if a Trailer Hub with a 6 on 5-1/2 inch Bolt Pattern is a 3.5k or 6k Axle
    Trailer hubs with a 6 on 5-1/2 inch bolt pattern can have an axle weight capacity of between 3,500 and 6,000 lbs. The diameter of the axle will be your next place to look to narrow down the capacity. If it is 2-3/8 inches it's going to be a 3,500 lb capacity or if it's a 3 inch diameter it's going to be a 6,000. For an EZ lube 3,500 with the right bolt pattern you would need part # 84656UC3-EZ, or for a 6,000 lb you would need part # 8-201-9UC3-EZ.

  • Is 84656UC3-EZ 10 Inch Hub Drum a Direct Replacement for Dexter 8-247
    You are correct. The # 84656UC3-EZ hub/drum you'd looked at with the 6 on 5-1/2 inch bolt pattern uses the same L44649 outer/L68149 outer wheel bearings and 10-19 grease seal as the 8-247 hub/drum like the # 8-247-50UC3-EZ you'd looked at. Since the inner and outer bearings and ID of the grease seal match up, the # 84656UC3-EZ would be a compatible replacement.

  • Hub/Drum Assembly Recommendation with a 6 on 5-1/2 inch Bolt Pattern for a Timbren Axle-Less System
    Yes we do, you would want the Trailer Hub and Drum Assembly # 84656uc3. This hub and drum has a 6 on 5-1/2 inch bolt pattern and uses the exact same bearings that the Timbren Heavy-Duty Axle-Less Trailer Suspension # ASR2KHDS03 is compatible with so it should work perfectly for you. The # ASR2KHDS03 lists its spindle/hub compatibility as being designed for L68149 inner bearings and L44649 outer bearings, which is exactly what the # 84656uc3 comes with.

For a Timbren System part # ASR3500S05 would work well and then for a 6 on 5-1/2 inch hub to install on the spindle you would want part # 84656UC3.

  • Hub/Drum Recommendation for 1967 Oasis Trailer Getting Dexter 3,500 lb Hub/Drums
    Thanks for getting me all of the info listed. I can tell you really did your homework on this. But to answer your question there isn't a modern style of bearing that's going to allow you to reuse the hub/drums you have now since the bearings and dimensions do not match anything we offer now. So since you are going to a Dexter 3,500 lb axle and you have a bolt pattern of 6 on 5-1/2 inch the hub/drums you'd need are the # 84656UC3-EZ and you'd be set. This comes with the correct bearings...
