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"

  • How to Determine Axle Capacity on Old Trailer
    I do have a way to give you an idea as to what the axle capacity is for your trailer but I called Dexter Axle and they were not able to look up the number, "021362" that you provided due to its age. If you have a leaf spring axle then what you are going to want to do is measure the diameter of the axle tube. Once you measure the axle tube you can then use the chart below to give you an idea of what the weight capacity is. If you have a torsion axle then your next best option would be to...

  • Trailer Idler Hub that Uses Bearings 25580 and LM67048 with a 2-1/8 Inch Inner Diameter Seal
    For an idler hub that takes inner bearing # 25580 and outer bearing # LM67048 you can use # 8-213-5UC1 which is rated for 5,200 to 6,000 pound axles and has a 6 on 5-1/2 bolt pattern. This is the only regular idler hub we have that takes those bearings and a seal with 2-1/8 inch inner diameter. I have linked a video review of this hub for you.

  • How to Increase Trailer Tire Weight Capacity
    A trailer can be fitted with higher-capacity axles (or hubs, or wheels or tires) to increase the weight capacity safety margin but this does not increase the overall trailer weight rating. Changing a trailer's tires to a higher weight load range is a popular and much easier way to add weight safety margin. In your tire size 235/80-16 we offer radials in either Load Range E or Load Range G. Please refer to the linked page. The Provider ST235/80R16 Radial Trailer Tire # PRG80235 is rated...

  • If a Hub Fits 5K to 7K Axles, What Makes a 7K Axle More Heavy Duty than a 5K Axle
    A hub such as # 42866UC3 fits on the spindle which is welded to the axle and spindles can have different capacities as well. The camber or bow of an axle, its length, the quality of materials, the diameter, and many other factors go into its capacity rating. So in a way, yes, it is all in the axle tube, that and other factors as mentioned above. Ideally you will get parts that are rated the same as the axle. Otherwise you can end up with a poor ride or tracking problems. Adding higher...

  • Recommended Hub w/ a 8 on 5-1/2" Lug Pattern and a 28580 Inner Bearing
    Thanks for the information. For a 8 on 5-1/2" lug hub with a item # 28580 inner bearing you'll want the Dexter Trailer Hub and Drum Assembly item # 42866UC3. This is a 12" diameter hub that fits 5,200 lbs to 7,000 lbs axles. It fits a item # 14125A outer bearing.

  • Is There An 8 On 6-1/2 Bolt Pattern Hub/Drum That Uses A 25580 Inner Bearing And 15123 Outer Bearing
    Having the 8 on 6-1/2 bolt pattern and the # 25580 inner bearing is completely normal, but having the # 15123 outer bearing with this definitely is not. However, the # 15123 bearing will have an inner diameter of 1.25", which happens to be the exact same as the # 14125A bearing. The # 25580 inner bearing and # 14125A outer bearing is commonly found on a hub with the 8 on 6-1/2 bolt pattern and a 5,200 to 7,000 pound axle. With all that said, the Dexter Trailer Hub and Drum Assembly # 42866UC3...

  • Replacement Hub Assembly for Axle with 1-1/4 Inch Diameter Outer and 1-3/4 Inch Inner Bearing
    If you do not need electric brakes on your axle, I recommend the Dexter Trailer Hub Assembly # 42865-KIT. This assembly includes the # 25580 inner bearing, the # 14125A outer bearing, and a grease seal with a 2-1/4 inch inner diameter needed for the spindle on your existing axle. Also included with the assembly are the races, grease cap, wheel bolts, and lug nuts. The hub has a 8 on 6-1/2 wheel bolt pattern. One hub assembly is included for the part number.

  • Would Trailer Hub # 42865-KIT and Hub & Drum Assembly # 42866UC3 Work Well Together
    Yes, the Trailer Hub Assembly # 42865-KIT and the Trailer Hub & Drum Assembly # 42866UC3 would work well together for having a brake axle and an idler axle. The both have the same bolt patterns, weight capacities, and use the same bearings so they would work very well together. I would recommend you install the brake axle on the axle closest to your tow vehicle. I attached a video of how to remove and re-install hubs from a spindle.

  • Hub and Drum Assembly Needed for a 1979 Featherlite Horse Trailer with 6000lb Axles
    It sounds as if you will need the trailer hub and drum assembly # 42866UC3, which has an 8 on 6-1/2 bolt pattern and uses the # 25580 inner bearing (1.75 inch inner diameter) and # 14125A outer bearing (1.25 inch inner diameter). This assembly works with a 12 x 2 inch brake assembly like left hand electric brake assembly # 23-105, and with wheels that use 1/2 inch studs. There are numerous other possibilities, like 12 x 2-1/4 inch brake assemblies, different bearing part numbers, and...

  • Recommended Hub And Drum And Brakes For Tri-Axle Gooseneck Trailer With 7,000 Axles

I have attached a link to the hub and drums we have that are designed for a 7,000 lb axle you can check out. If you do not have EZ-Lube axles I recommend part # 42866UC3. These come with the bearings, races, seal, grease cap, wheel bolts and lug nuts. If you do have EZ-Lube axles I recommend part # 42866UC3-EZ. These are the same hub and drum but have...

  • Comparing Dexter K08-219-90 and K08-219-9B Hub and Drum Assemblies
    The only difference between the # 42866UC3 and # 8-219-4UC3 is the grease seal. The # 8-219-4UC3 uses a # GS-2125DL grease seal with an inner diameter of 2.125" and outer diameter of 3.376". The # 42866UC3 uses a # GS-2250DL grease seal with a larger 2.25" inner diameter.

  • Replacement Hub/Drums and Brake Assemblies for 2018 Jayco Eagle 336FBOK
    Since your 2018 Jayco Eagle 336FBOK has a 6k axle the correct drum brake assemblies would be the part # 23-458-459. It sounds like you are also looking for replacement hub/drums as well. For that the correct part number is # 42866UC3. You should note that the brake assemblies are sold as a pair, one for each side of the axle, and the hubs are sold individually.

  • What is Hub Bore of Dexter Trailer Hub with 8 on 6-1/2 inch Bolt Pattern
    The pilot hole for your wheel will need to be 4-3/4" or more to be used with Dexter Trailer Hub and Drum Assembly # 42866UC3. Since your wheel has a center bore of 4.9 inches it would easily fit on this hub.

  • What Information is Needed to Pick Out the Correct Replacement Hub and Drum
    In order to determine which replacement hub and drum you would need to replace your current parts, you will need to either get the numbers that are stamped on your bearings, or you will need to get some precise measurements from your spindle. The measurements you need will be where the seal and bearings ride. Check out the picture I attached to see which measurements are needed.

    The brakes you mentioned are for 7,000 lb axles and are 12-inch assemblies, similar to the Dexter Electric Trailer Brake Kit # 23-180-181, but that is just one part of the equation in regard to determining the correct hub and drum.

These hubs are for agricultural applications and are rated for 3,000 lbs axles and have a 4 on 5 bolt pattern. This kit is sold individually so you will need to purchase two.

The inner bearing # 25580 is the same for both this assembly and what you currently have, and the # 14125A outer bearing has the same inner diameter as the # LM67048, so it will still be compatible with your spindle. You can make this conversion without issue. For idler hubs I recommend the Dexter # 8-231-9UC1-EZ. These particular hubs...

    For your 2990 lb rated axle with the same 2-3/8 inch diameter as 3500 lb axles, there may be other factors such as the outer wall or bearing sizes that ultimately reduce the rating of your particular axle below 3500 lbs.

  • Recommended Dexter Hub/Drum Assemblies for 5,200 lb and 6,000 lb Axles
    Some of the Dexter hub/drum assemblies are rated for 5200 lb axles and some are rated for 5200 to 7000 lb axles. The only difference is bolt pattern. There are 6 on 5-1/2 assemblies that will only be compatible with 5200 lbs where the 8 on 6-1/2 inch bolt pattern will stretch to the other weight capacities. The most common hub and drum for your axle size is the Dexter Trailer Hub and Drum Assembly - 5,200-lb to 7,000-lb Axles - 12" Diameter - 8 on 6-1/2 # 42866UC3. If you have the EZ...
