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"

Installed easily, glad it's pre-greased. Great deal! Shipping from e-trailer was fast. Other websites didn't provide enough info to know if I was ordering the right part. etrailer did a good job of describing what was being purchased so they won my business. 610020

Item arrived exactly as described, assembled, greased and ready to be installed. I literally took it out of the box, removed the plastic protective caps, and slipped it over the axle stub. It fit perfectly and works great. Very pleased with product cost, fast shipping and ease of installation. 523174

I was looking for idler hub assemblies for my 6' x 12' utility trailer. Apparently 5 studs on 5" circle is not that common. Most trailers are 5 on 4.5. The entire experience with etrailer was great. They helped me with the selection of the idler hub assemblies and assured me I was selecting the correct hub assembly based on the bearing numbers that came out. The ordering was slick, especially with PayPal, and the least expensive delivery method was fast. Ordered them on a Thursday and UPS delivered them Monday morning. Excellent quality and a fair price. Will definitely use trailer.com again. 598022

Went on smooth, no issues so far, the cover was a little tough getting on, so I'm sure it'll be fun taking back off to grease. Still, I'd rather have a tight seal. Quality of the bearings, and hub seem to be above par. 607638

This was a complete kit, all the pieces were included and there were no surprises. This was part of an axle replacement, the entire job of bolting on the axle and the hubs took less than 2 hours. I chose this hub so that I can use the truck spare tire for the trailer, too. 288421

Thats an awesome trailer! Exactly what Id like to build to pull behind my JK. Im hoping these 5 on 5 hubs are the Jeep wheel pattern so I only need one spare?

-- comment by: Phil P - 03/17/2015

As long as the hubs/wheels on your JK are 5 lugs on a 5-1/2 inch pattern, these hubs should be fine. The only other thing to consider is the pilot hole on the wheel clearing around the center of the hub.

I needed to replace a hub with a 5x5 pattern. The only choice in this pattern was the star shaped hub. This seems to be a sturdy hub but I wish it was a full hub, seems heavy built though, time will tell if it holds up. I like that it comes complete with bearings, dust cap, seal and lug nuts. 118191

  • Recommendation for Converting Fleetwood Neon Pop-Up to Axle-Less Suspension System with Jeep Tires
  • To convert your offroad trailer to the Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle w/ Brake Flange - 5,200 lbs # TASR5200S03 you will either use a crossbrace for your trailer frame at the axle location or you will add a 2 inch square tube between the assemblies (not included) into the integrated holes of the assemblies. This will give you much more ground clearance than a standard axle and will also include the suspension needed. Unfortunately that 5,200 lb Timbren...

  • Timbren Axle Less System and Hub with 5 on 5 inch Bolt Pattern Recommendation
  • First thing you will need to know to determine the correct Timbren system will be the total axle capacity you would need for your trailer. We have ones that range from 1,200 lbs up to 7,000 lbs. We don't have a ton of hubs with a 5 on 5 inch bolt pattern, but if you went with a 3,500 lb Timbren system like part # ASR3500S06 you could use the part # 84556UC3 for a hub/drum or part # 84550BX for just a hub. The # ASR3500S06 has a 4 inch lift built into it so it would be great for an...

  • Replacement Hubs for Retired Army Kassel Mfg 3/4 Ton Cargo Trailer
  • Unfortunately I can't confirm a fit for your trailer. You will need to pull a hub and get the bearing numbers or measure the spindle with a digital caliper for me to be able to confirm a fit. If you pull the hub and look at the face of the bearings, you should be able to see a number printed. That number on the inner and outer bearing of a hub will help me get your spindle compatibility. If you can't see the numbers on the bearings, then you will need to use a digital caliper like...
