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"

  • Replacement Bearings for Dexter Axles with 12000-lbs Capacity
    The Replacement Trailer Hub Bearing # 3984 has an inner diameter of 2.625", so it's possible that it will work on your 12,000-lbs Dexter axle, but you'll need to know what bearings are in your hubs to confirm this is the correct replacement bearing. This bearing is designed to fit in Dexter hubs with part numbers: 8-216-5, 8-214-8, 8-217-5 and 8-272-5; the only hub we currently have available out of that group is the 8-214-8 with part # Dexter Trailer Idler Hub Assembly for 12,000-lb Axles...

  • What Weight Capacity is an Axle with 8 Lugs
    There really is a wide range of axles that could potentially be on this trailer. We carry hubs with 8 on 6-1/2" bolt patterns that can be used on axles anywhere from 5200-lbs capacity, like the # 8-219-4UC3-EZ all the way up to 12000-lbs like the # 8-214-8UC1. The best way to determine the axle capacity is going to be checking the spec sticker/plate that can be found towards the center of the axle. If you can't find a spec sticker, knowing the bearings, races and seals also may provide...

  • Hub Assembly for Big Tex Trailer With Tandem 12k Axles
    We do offer one 12,000 lb idler hub assembly which is the Dexter # 8-214-8UC1. This uses # 3984 inner and # 28682 outer bearings. Assuming you're using over the hub rotors like what is found in the # K2R1258L12 these will work as a replacement.

  • Parts Needed to Add Electric Brakes to Trailer With 12,000 Pound Air Brakes
    More than likely you will be able to just add a brake flange and won't need to swap out the spindles. If by 12k air brakes you mean you have tandem 6,000 lb axles then you could use the Brake Mounting Flange for 3" Round Axle # 4-44-1. You will want to take this to an axle shop for installation since they will need the proper equipment to mount it. If you actually have 12,000 lb axles then we do not have a brake flange or spindle/brake flange that large. If you can't find either then your...

  • Will Dexter Idler Hub for 12k Axles Fit Lippert Axle
    More than likely your Lippert axle uses the standard # 3984 inner and # 28682 outer bearing. I would double check to be sure. Assuming that is correct, the Dexter Trailer Idler Hub Assembly for 12,000-lb Axles # 8-214-8UC1 will fit.

  • How to Remove the Rotor on 12k Dexter Disc Brake Kit
    When removing the rotor on your 12k Dexter disc brakes, all you need to do is pull it off of the hub assuming you have already removed the caliper. The only thing that secures it to the studs is the wheel and lug nuts when you put the wheel on. It is possible that yours is giving you some difficulty if dirt or rust has built up in some way, but you should still be able to take it off. Just be careful to not damage anything else when trying to break it loose. I have attached a video from...

  • Converting from Electric to Hydraulic Disc Brakes on 2019 Big Tex Trailer With 12,000 Pound Axles
    The Kodiak Disc Brake Kit # K2R1058D11E is for 9,000-10,000 lb Dexter axles. Assuming you have a standard duty Dexter or Lippert 12,000 lb axle, the correct kit would be the Kodiak Disc Brake Kit - 11" Rotor - 8 on 6.5 - Raw Finish - Leaf Spring - 12K - Dexter/Lippert # K2R1258L12. This kit fits an idler hub assembly like the # 8-214-8UC1. You will need to verify which axles you have in order to make sure this will work, it is not for use with 12K HD axles. In addition to the disc brake...

  • Disc Brake Assemblies For Changing A 12,000LB Dexter Axle To Hydraulic Disc Brakes
    We have the Kodiak Disc Brake Kit # K2R1258L12 that is designed to fit your 12,000lb Dexter axle.
