Corrosion Resistance for Marine Use

This trailer hub 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 - 8-213-51 Review

Today we're going to take a look at the Dexter Galvanized Trailer Hub for 6,000-pound axles. This has a 6 on 5-1/2-inch bolt pattern. This is a marine-grade trailer hub that will fit on either axles. This does come with the inner and outer bearing races pre-installed. You can see the inner bearing race right there and the outer bearing race right there. Now, to install this onto your axle, it will require both inner and outer bearings. It will require a grease seal, a grease cap, and lug nuts.

All of those items we do sell separately on our website. Now, this hub does have a gal-dec 00:00:30 zinc plating, which has a 500-hour salt spray rating. This product is able to withstand 500 hours of constant exposure to the saltwater mist. This 500-hour salt spray rating will indicate that this product is not only durable enough to last in fresh water environments, but it can also be used on trailers that come into contact with salt water. It's ideal for use on boat or snow mobile trailers and durable enough for salt water applications. This is designed to fit on a 6,000-pound axle. The bolt pattern again is a 6 on 5-1/2-inch bolt pattern.

The wheel studs are 1/2 inch diameter, so they do use 1/2 inch by 20 size lug nuts. Weight capacity on this hub is 3,000 pounds, so when this is used with one on the other side of the axle, it'll meet the 6,000-pound maximum capacity. Now, just to give you some part numbers for the bearings and all those parts that are required to install this. The inner bearing it uses is part number 25580. The outer bearing that goes in here is 15123. The grease seal that's used on the back is either part number 10-10 or 10-36.

The grease cap that would go on the outside here, you can use either the F001520 or the DC250L-DCRP, and then the lug nuts, the 1/2 inch by 20 lug nuts that fit on these studs would be part number X1023R. That should do it for the review on the Dexter Galvanized Trailer Hub for 6,000-pound axles with the 6 on 5-1/2-inch bolt patter.

See what our Experts say about this Dexter Axle Trailer Hubs and Drums



  • How to Determine Trailer Axle Rating from Axle Diameter and Bearings Used in Hubs
    Often an axle's weight rating will appear on a sticker or plate on the axle beam itself, or sometimes the trailer's main identification sticker will include axle ratings. This is helpful unless of course the axles have been replaced during the trailer's lifetime. Axle diameter can get us at least in the right weight capacity neighborhood. An axle with 3-inch diameter typically has a 6K or 7K weight rating. One that is 3-1/2-inches in diameter is usually rated for 8K. In rare instances...

  • Can a Hub/Drum Be Switched Out For An Idler Hub On a 6,000 Lb Trailer Axle
    Yes, you can replace the hub/drum that you have on your trailer with a standard idler hub assembly. In order to determine if the Dexter Trailer Idler Hub Assembly part # 8-213-51UC1-EZ is correct you will need to verify that your spindle uses a 25580 (1.75" inner diameter) inner bearing, a 15123 (1.25" inner diameter) outer bearing, and a GS-2250DL (2.25" inner diameter) grease seal. This may require you to read part numbers or measure to verify. If the above is true then you will be...

  • Bearing Buddy Size for Dexter 6K Trailer Hub Assembly # 8-213-51UC1
    The hub assembly you referenced, Dexter 6K Trailer Hub Assembly # 8-213-51UC1, has a hub bore of 2.430 inches. I pulled a sample from our warehouse and took a measurement with a precision digital caliper. Based on this hub bore the correct Bearing Buddy is part # BB2441. This set of bearing protectors includes rubber covers.

  • Idler Hub for Use on Tie Down Axle Part 46648 from Venture Trailer
    I was able to find some details about the Venture square axle part 46648 in my research. This square axle is indeed rated for 5200-lbs, is 98-inches long overall including spindles, is galvanized and works with spring centers of 72- or 75-inches. A bit more digging allowed me to determine the bearings required for the included spindle are inner bearing # 25580 and outer bearing # 15123. Since these are the same bearings used in the hub # 8-213-51UC1-EZ it will fit on your spindles. This...

  • What Hubs Will Work with the Timbren Heavy-Duty Axle-Less Trailer Suspension Part # ASR35HDS02
    The Timbren Heavy-Duty Axle-Less Trailer Suspension part # ASR35HDS02 uses a 25580 (1.750") inner bearing, 15123 (1.250") outer bearing, and 10-10 (2.125") grease seal. As long as the hub you are wanting to use has these bearings/seals then yes it will work for you. The bearing numbers should be stamped into the bearing but if not you can use a digital caliper like part # PTW80157 to measure them. If you are looking for just an idler hub and your wheels use a 6 on 5-1/2" bolt pattern,...

  • Determining Correct Replacement Bearings, Races, and Seals For 2013 Discount Boat Trailer
    Based on the grease seal part number you found on the grease seal on your 2013 Discount Boat trailer you will need the # GS-2250DL, but for the bearings and races you will need to remove on of your hubs. The grease seal you have is commonly used on 5200-8000lb axles of which there is quite a few different bearing combinations. The easiest way to find your bearing combination is by removing one of your hubs and looking for the bearing numbers stamped in both the inner and outer bearings...

  • Can I Use Idles Hubs Instead of Drums on the Timbren Axle-Less Trailer Suspension
    Yes the Dexter Trailer Idler Hub Assembly for 6,000-lb E-Z Lube Axles part # 8-213-51UC1-EZ will work with the Timbren Heavy-Duty Axle-Less Trailer Suspension part # ASR35HDS05. I was able to confirm that they use the same bearings. The reason that they say they are for drums is that typically there are brakes on larger trailers like what the spindles are designed for.

  • Availability of 6k Trailer Hub with 6 Lug Bolt Pattern Pre-Greased
    We have pre-greased 6k trailer hubs with 6 on 5-1/2 inch bolt patterns like the etrailer part # AKIHUB-655-6-K but we do not have any that are galvanized. This would still work great in a marine application though.

  • Can I Use a Timbren Axle-Less System on a Boat Trailer That is Used in Salt Water
    Yes. Timbren Axle-Less Suspension systems like the # ASR35HDS05 have a thick powder coating on them, so they could be used on a boat trailer that gets submersed into salt water and do just fine. The spindle uses # 15123 outer and # 25580 inner bearings and you'll want to use hubs with either a dacromet plating or a galvanized finish. The hubs I recommend would be the Dexter Trailer Hub and Drum Assembly - 6,000-lb Axles - 12" Diameter - 6 on 5-1/2 - Galvanized # 8-201-51UC3 which would...

  • Replacement Hub for Tie Down Engineering 81091
    Yes, the Dexter Trailer Idler Hub Assembly # 8-213-51UC1-EZ will work as a direct replacement for your Tie Down Engineering 81091 hub. Based on my research your 81091 hub is rated to be used on 6,000 lb axles, has a 6 on 5-1/2" bolt pattern, uses Inner Bearing # 25580, Outer Bearing # 15123 and Grease Seal # GS-2250DL. This is also what the galvanized Dexter Hub # 8-213-51UC1-EZ uses so it will work as a replacement.

  • Replacement Idler Trailer Hub Assembly For 2002 Load Rite 6 Lug Tandem Axle Boat Trailer
    You are needing either the Galvanized Dexter Trailer Idler Hub # 8-213-51 or Stainless Steel Kodiak Trailer Hub # KH42655S. Of these I recommend the stainless steel for superior corrosion resistance. You will need a Inner Bearing # 25580, Outer Bearing # 15123 and Grease Seal # GS-2125DL for each hub.

  • Which 6 Lug Trailer Hub Does Best in Saltwater Application
    Since the # AKIHUB-655-6-K is just painted steel it would not be my first choice for a saltwater application as it would pretty quickly start to corrode. The absolute best option would stainless steel like the Kodiak part # KH42655S as stainless steel won't corrode. Next best option would be the galvanized part # 8-213-51UC1 which won't be as resistant to corrosion as stainless but would do a much better job than just paint as it's a zinc coated steel which does a pretty decent job with...

  • Replacement Spindle And Hub For 6,000 lb Axle on Boat Trailer
    The information was helpful, thank you, and spindles are replaceable, they just need to be welded on by a qualified professional. In regards to the hub, there are a couple of options, depending on your current hub's bolt pattern. Basically, just if your current wheels fit hubs with 6 lugs or 8 lugs. So for a replacement spindle and accompanying hub for a 6,000 lb axle, here is what you will need: - #42 E-Z Lube Spindle with Flange for 5.2K to 7K Trailer Axles # TRU37FR - 6 on 5-1/2"...

  • Dexter Axle Hub Conversion for 14.5 Inch or 15 Inch Wheels on Equipment Trailer
    Thanks for the information on your trailer. For your axle with brakes I recommend the Trailer Hub and Drum Assembly - 5,200-lb and 6,000-lb E-Z Lube Axles - 12" - 6 on 5-1/2 # AKHD-655-6-EZ-K if you have the spindles with the integrated grease zerk. If you have standard spindles, I recommend # AKHD-655-6-K which have the standard grease cap instead. These assemblies will fit perfectly with your axles based on the bearing and seal information you gave as well as 14.5 inch wheels. Then...

  • Recommended Compatible Hubs for Use with Timbren Off-Road Suspension System ASR35HDS02
    In order to use 6-on-5-1/2-inch bolt pattern hubs on a Timbren axle-less suspension system those hubs will have to use the same bearing set as the hubs intended for that system. In the Timbren system # ASR35HDS02, for example, which has 4-inches of lift and is rated for 3500-lbs and off-road tires, the bearing set is inner bearing # 25580 and outer bearing # 15123.
