Shipping SpecialTrailer hub-and-drum assembly includes lug nuts, inner bearing (25580) and race, outer bearing (14125A) and race, grease cap and grease seal. Fits 5,200-lb to 7,000-lb axles with spindles that require a 2-1/8" ID grease seal.
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.
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.)
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.)
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.

Today were going to review part number 8-219-4UC3. This is the Dexter Trailer Hub and Drum Assembly with an 8 on 6-1/2-inch bolt pattern for 1/2-inch studs. This trailer Hub and Drum Assembly will include your eight 1/2-inch cone seat lug nuts. It will include the inner bearing, part number 25580, it will include the outer bearing part number 14125A, it will include the grease seal which is a 2-1/8 inch diameter grease seal, and will also include the grease cap which goes over the hub right there. Now the bearing races are included also. They are already installed, pressed into the hub.
There is the outer, and when I spin this around youll be able to see the inner race right there. The application on this Hub and Drum Assembly will fit the 5200 to 7000-lb Dexter axles. It has a drum dimension of 12 inches by 2 inches wide. The stud diameter for the wheel studs is 1/2 inch. The bolt pattern is an 8 lug 6-1/2 inch pattern.
Now the capacity on this Hub and Drum assembly is 3500 lbs. So when this one is used with another Hub and Drum Assembly on the other side of the axle it will give you the max of 7000 lbs. I do want to give you a few dimensions. The bolt pattern which we mentioned is 8 lugs 6-1/2 inch. So basically the way you would measure that is on a Hub and Drum that has an even amount of lugs which in this case would be eight, you just take one or pick any of the studs and measure from the center of that to the one directly across from that.
So if you go from center to center it will be 6-1/2 inches and that will give you the 8 lug 6-1/2 inch bolt pattern. The other dimension I would want to give to you is the drum size. It is 12 inches. Thats the measurement of the inner of the drum. And then the width will be 2 inches.
So this Hub and Drum assembly will work with 12-inch by 2-inch brake assemblies. And that should do it for our review on part number 8-8-219-4UC3.
