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"

Comments
I hate to see that parts arrived damaged out of the hub assembly. I will have out customer service team reach out.
-- Etrailer Expert Jenny N - 08/13/2022


by:

Very well detailed order recap. I like how the videos and parts details are shown with the current order. Well done.




by:

The hubs are great, easy install and perfect fit. Can't wait to try out them and the new electric brakes I installed.




by:

These are to replace old 7 1/4" brakes on an older pop up camper frame that I built a small camper on. Looks they will work perfectly with the new Dexter 7" brake assembles I have.




by:

Erica at etrailer.com was extremely helpful in helping me select the right breaks for my trailer application. The ship time was incredibly fast installation was a breeze and customer service is top notch!!!




by:

Seal is bent a bit. I can still use it.




by:

I had to replace one hub on my pop-up camper and decided I should do both wheels. The parts I ordered came very quickly (3 days), without having to pay extra for quick shipping. The parts matched perfectly and the job went very smoothly. My only complaint is that one of the hub covers/grease seals was dented and bent. It looks like it was damaged during shipment as it was not packaged separately but instead was taped to the outside of the hub. Luckily one of my old seals was reusable and everything worked out.




by:

corect part, good quality.




by:

Not sure if these hubs are going to work. Spent a hour today installing and found small size differences between old and new ones. I thought kit was supposed to include everything, but it was missing cotter pins and bearing washers. This was not my first purchase from etrailer, but I could of used more information on hub dimensions. I was replacing surge brake hubs for a 1992 Jayco popup. I would suggest adding links to mechanical drawings with guidance on what and where to measure to get the best product.




by:

Ordered 4 parts as part of an update to my tandem axle trailer. The correct lip seal is included with 3 and one has the wrong lip seal(too wide and wrong ID). Compatibility information with other parts ordered (brake assemblies in this order) is valuable.




by:

A year ago I bought these as part of an overhaul for a 1976 coleman pop-up camper. Many parts on it were obsolete, so I had to change the drums along with the entire suspension. I am pleased to say they work great with my electronic brakes! We've taken our refurbished trailer on 2 long-distance trips (including one into the mountains) and the brakes and drums perform very well!




by:

Everything in one package taped to the hub. I would have offered more protection for shipping to the bearing and seal then just taping it to the hub but it did arrive unscathed. Quality seemed good. Went together easy. Lost the first dust cap on my first trip around the block for a brake adjustment test. Lost the second on the second trip (about 10 miles). I ordered replacement dust caps and the tap on tool. Not sure if I didn't have them on well enough or if there is a product problem there. I have done a lot of these and never had a problem before.




by:

First of all, the product description on the eTrailer website was very detailed and very complete. With all the different axle sizes and types out there, it was nice to have the specs to make sure I was ordering the right part.

I like the shipping tracker. It's easy to use, and I knew where the shipment was, and when to expect delivery. That was nice, because my hub arrived a day later than I thought it would. (When you order on Good Friday, on Easter weekend, 3 day shipping might take an extra day. I should have expected that.)

I thought that rebuilding the existing hubs would be a good idea. And it was. But while driving the new bearing race into place, I let the race get crooked, and I cracked the hub.

The old hub uses bolts to mount the wheel. The new hub has studs and lug nuts, which makes tire changing much easier. The new hub comes with the race pre-installed, just have to apply grease and tap in the rear seal. very easy.

All things concidered, I'm very happy with the entire process, and will probably order a roof rack for my pop up camper from etrailer in the near future.




by:

I received my parts, packed the bearings, installed the brakes and backing plates assemblies. installed the drum and hubs, adjusted the brakes and on the road we go. It took 1 hour to do both sides and they fit perfect. Thanks etrailer.com




by:

The first 2 drum and hub combos i got were machined crooked and the second set had to be turned on a drum lathe before the brakes would work properly. I lost time and money being broke down and paying to have the drums checked and turned at a machine shop. Maybe made in China? The people at e trailer were helpfull and prompt no complaints there, just the quality of product.




by:

Electric Brake kit for trailer this time.
The parts are very acceptable and the service is supreme.
Couldn't get any better service anywhere. I've bought a lot of items from etrailer for a couple years now. I have had great experiences with each and every order.

  • Replacement Brake Drum for a 1998 StarCraft 2408 Pop Up Trailer
    When trying to find the correct drum brakes, a measurement of the inside drum diameter and the depth of the drum will be needed. See attached picture. The drum that you referenced, # 8-173-16UC3, measures 7 inches in diameter and 1-3/4 inches deep. Also this drum will have a 4 on 4 bolt pattern. If your drum has this measurement and your current shoes measures 1-1/4 inches wide, then this will be the correct part and work it well for your pop up camper. I have also attached an article...

  • Picking Out Replacement Axle for 2005 Coachman Clipper
    That picture of your wheel is pretty crazy! I hope the damage was minimal and no one got hurt! If you damaged a bearing there's a pretty good chance you also damaged the spindle it rides on. You'd need to inspect the spindle to make sure it's free of damage. If it's damaged it's probably a good idea to just replace the axle since you are already at the point of replacing most of the axle. Especially if the hubs are currently pretty rusty on both sides most likely. You are going to need...

  • Recommended 7-Inch Hub And Drum Assembly For Electric Brakes
    We do offer just the 7-inch hub and drum without bearings, seals, and races for hydraulic brakes but we do not sell the hub and drum for electric brakes without those components. The hub and drum assembly I recommend is part # 8-173-16UC3. This does come with the bearings, races, grease seal, grease cap, and lug nuts and is rated for 2,000-lb axles. This assembly does have a 4 on 4-inch bolt pattern.

  • Can Electric Trailer Brakes be Added to a Harbor Freight Kit Trailer
    Neither of those Harbor Freight trailers has brake mounting flanges on the spindles. To add electric brakes you would have to have brake mounting flanges welded on. This is a precision job that requires a special jig and someone with experience in welding on flanges. I have included a link to the flanges we carry to the right. You would also need to replace the idler hubs on the trailer(s) with hub and drum assemblies. The problem with that is the Harbor Freight trailers use uncommon bearings...

    Sounds like you have an electric over hydraulic actuator on your second trailer. Some brake controllers like the Prodigy P2 brake controller part # 90885 can be switched into EOH mode and will work to control the brakes easily. Some actuators have adapters that will allow any electric brake controller to be used with them but these aren't always reliable. Your best option would be to go with a brake controller that is confirmed to work on EOH brake systems like your trailer has like the...

    In order to find a replacement axle for your Harbor Freight trailer you will need to take some measurements to determine the correct axle length. The most important measurement is the distance from hub face to hub face. Additionally, you can measure the spring center distance. When 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 these measurements.

  • Can 7 x 1-1/4 Inch Electric Trailer Brakes be Used w/Hydraulic Brake Hub for 7 x 1-3/4 Inch Brakes
    Hub and drum assembly # 8-276-5 is not a proper fit for 7 x 1-1/4 inch brake assemblies and should not be used with them. I know you are looking to save some money but believe me, you can spend a little now on the correct hub and drum assembly, # 8-173-16UC3, or a lot later after the additional length of the hub stress the bearings and spindles and you are looking at replacing the axles.

The outside diameter of the hub for the # 8-276-5 hub measures 2.06 inches.

    It sounds as if the wheels that are on your trailer are hub piloted, meaning that the center of the wheel is mated to the outer diameter of the hub not on the mounting studs. In this case the dimension of the hub protrusion is critical for balance of the wheel and tire. At this time we do not carry hub piloted hub and drum assemblies.

The Kenda 205/65-10 Bias Trailer Tire with 10" White Wheel part # AM3H410 will be a great option for this.
