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"

Item was shipped and delivered very quickly. Shipping container was damaged, but items were fine. Top quality product at a Great Price. 4 stars because shipping container was to big for heavy drums. Drums were able to move freely. Corner of box had a large tear in it (open). Nothing fell out of container, drums had some rub wear marks. Thanks for the fast shipment and quality product.

  • 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.

    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.

  • 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...

    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.

  • Rubbing Noise After Hub/Drum Install
    Thank you for the feedback, we sure do appreciate it! It's hard to say what the rubbing noise you are hearing is but I suspect the shoes on the backing plate are coming into contact with the drum which is completely normal but don't forget to adjust them prior to towing. I would then start with lubrication. In addition to packing each of the bearings before assembly you will also need to fill them with the right amount of grease. I would also make sure no dirt got into the grease and the...

  • Should Grease Be Added to EZ Lube Trailer Hubs if the Bearings were Manually Packed with Grease
    On EZ lube hubs and axles you would want to add grease until it is full (when you see it flow out). When that happens it indicates that the proper amount of grease is in the hub. Having the bearings packed and the little bit of grease you have added is probably fine but it is better to be safe and fill 'em up!

  • How Tight Should Trailer Bearings Be When Installing on a Spindle
    Trailer bearings can fit pretty tight to the spindle, but they would not ever need to get pressed on. They should not be so tight that you have to really pound on them to fit but they can require a little bit of effort to get them to slide onto the spindle. When installed there should be no play between the inner surface of the bearing and the spindle. I have attached a link to a video that shows how to remove and reinstall trailer hub components you can check out.
