Corrosion Resistance for Marine Use

This trailer hub assembly has a zinc coating that resists corrosion, making it ideal for use on your boat or snowmobile trailer. All GAL-DEX hubs undergo a test in which they are sprayed with a 5-percent salt solution to determine corrosion resistance over time. These products are able to withstand 500 hours of constant exposure to the saltwater mist. This 500-hour salt spray rating indicates that a product is not only durable enough to last in freshwater environments, but it can also be used on trailers that come into contact with saltwater.


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"

Video Transcript for Dexter Axle Trailer Hubs and Drums - Hub - 8-213-51UC1 Review

Today we're going to review part number 8-213-51UC1. This is the Dexter Trailer Hub Assembly for 6000-pound axles. It has the 6 on 5-1/2-inch bolt pattern and the GAL-DEX finish on it. This marine gray trailer hub assembly will fit on idler axles. It includes everything shown on the table here, both the inner and outer bearing are included. The hub assembly right here is included. Now the bearing races are actually pre-installed.

There's the outer bearing race. There's the inner bearing race. It also includes the grease seal, the grease cap and six of the 1/2-inch lug nuts. This trailer hub assembly has a zinc GAL-DEX coating on it which will resist corrosion. It makes it ideal for use on your boat or snowmobile trailer. All of the GAL-DEX hubs undergo a test in which they're sprayed with a 5% salt solution to determine the corrosion resistance over time. These products are able to withstand 500 hours of constant exposure to that salt water mist so this 500-hour salt spray rating will indicate that the product's not only durable enough to last in fresh water environments but it can also be used on trailers that are used in salt water environments. Again, the application on this is 6000-pound axles.

The bolt pattern, again, is 6 on 5-1/2-inches. The wheel stud diameter is 1/2 inch so they included 1/2-inch lug nuts that will used to hold your wheels and tires to this hub. Now the weight capacity on this hub assembly is 3000 pounds. When this is used with one on the other side of the axle, it'll meet your 6000-pound weight capacity for that axle. Now, again, everything shown here is included. That should do it for the review on part number 8-213-51UC1, the Dexter Trailer Hub Assembly for the 6000-pound axles with the 6 on 5-1/2-inch bolt pattern.

The hubs were mostly good. A couple of the races had spots of surface rusting that needed attention before install. The packaging had no weather protection from moisture. 151703
