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"

I’m very upset. I have ordered a lot of stuff from you, but this order really was bad. First off. It’s missing two Lugnuts. They gave me two that were too big as well. Also, dust covers do not fit. The solid ones do at least I think the ones with the rubber metal do not fit. I know they are hard to get in, and I am very experienced with putting them in and I could not get them to go in. Hopefully I haven’t tried them but the solid dust covers will work. If not, I will have to buy some bearing buddies. I don’t know if I will be using you again cheap Chinese stuff you’re selling

I am sorry that it came with missing hardware and that the grease caps are tough to tap into place. I will have our Customer Service team reach out to you.


Ordering was easy. I had some questions so I called. Tammie was very helpful and took my order. Hubs arrived in 2 days. Installed easily and works perfectly. etrailer is a great company to do business with.


They look good, will be installing and finishing a total light job, complete switch to electric brakes, safety trigger, battery by the end of next week. Thank-you etrailer!


Etrailer tech (George J) was great helping me pick this out for my trailer


Parts fit and worked as like they should. Fast shipping.


I put the new hub assembly on for my Lil' Hobo retro camper trailer. The hub assembly doesn't come with a washer and nut for the spindle, so you need to save your old ones or buy these separate if you don't have them. I put it on with new tires and wheels, upgrading from a four bolt to five bolt pattern.


Good price, right fit for my trailer per my research on your website. Short wait time on delivery. If product lasts, very pleased with overall experience with your company. Thank you.


Converted my trailer to 5x4.5 so I could use standard rims. Everything worked great. I ordered 2 drums and 2 hubs. Everything included.


Fast delivery
...the hub and bearing
set should include cotter pin had to replace them and for an additional couple of cent it far to Loews.
Thanks anyway


Got pre packed hubs for boat trailer they fit perfect just as described!! Fast shipping. Would recommend A plus


Not much to see, but here are pics of the installed new hub and Bearing Buddy.


My trailer originally had 5/ 4.75 hubs but decided to change to 5/4.5 hubs since my other trailer has the 5/4.5 hubs. Very happy with my purchase.


The hub is nice fit perfect. The included dust caps however had to be beaten in. Hard.


Just a quick note to say thank you to eTrailer for not only the quality of parts received but also to Melissa for the dedicated service and attention that was given to me when placing my order.

THANK YOU MELISSA for all of your help!
Looking forward to my next purchase!


Perfect fit. I can always count on Etrailer for all my trailer needs


I ordered the Idler hub (pre-greased) for the 3500 lb axle I have just installed it and it fit perfect


i told the person on the phone that both bearings were the same size and what was shipped was two different bearings. so i could not trailer my boat and missed out on the tournament. unexceptable


Worked like a charm great product


If you want a accurate review you may want to wait more than 2 hrs after delivery to request a review


Works great and fast shipping. Customer service is great too.


Product works great and was easy to install. I don't think it came with the castle nut pin, which might be problematic for some people who don't have hardware collections at their work space. It might help those who are unfamiliar with hub installation to get an install guide with the product. I could see someone over tightening the castle nut and ruining their new bearings.

Great! I checked them after about 250 miles of use and they were still tight and in great shape. They were exactly as described and perfect for my application.


Couldn’t have been more simple to purchase and install! A++


Super fast shipping, products always look well made.


Prefect fit!


Replaced hubs on 40 year old boat trailer. Cleaned up spindles with 350 grit sandpaper, packed bearings, filled remainder of wheel cavity with grease, assembled with new seal and old washer and hub nut. Good as new. I would have given them 5 stars if new washer and hub nut were included. I did learn that a dust cap driver can easily be made by cutting off a short piece of 2 inch sch. 40 pvc pipe. New lug nuts and dust cap were included.
