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 Review of Dexter Trailer Hubs and Drums - Idler Hub - 8-213-51

Hello everybody, this is Jeff at etrailer.com. Today I'm gonna take a look at this Dexter galvanized trailer idler hub for 6,000 pound axles. It has a 6 on 5-1/2 inch bolt pattern. Now, this is a marine-grade trailer hub which will fit idler axles. This has a nice zinc plating on it, gives you a 500-hour salt spray rating so it is ideal for use on a boat or snowmobile trailer and it is durable enough for saltwater applications. Now, this will include both the inner bearing race and the outer bearing race.

They are all pre-installed. It will require the bearings, the grease seal, the grease cap, and lug nuts which we do sell separately on our website. And we do list them on this product page of what part numbers you need. Now, this is a sturdy iron construction. This part is made in the USA.

Application, we mentioned this fits 6,000 pound trailer axles with the number 42 spindles. The wheel size that'll fit on this hub is 16 inches and larger. The bolt pattern is a 6 on 5-1/2 inch bolt pattern. And the wheel stud size is a half inch diameter. So the lug nuts you use on this will be the half 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 meets the 6,000 pound trailer axle rating. But that should do it for the review on the Dexter galvanized trailer idler hub for 6,000 pound axles with the 6 on 5-1/2 inch bolt pattern.

Dose this not come with the bearings?

Correct, the bearings do not come with this idler hub. It is just the hub, you will have to purchase the bearings separately. Check out part # BK3-110, this will have both the inner and outer bearings.

I carry one as a spare...you only break what you don't carry, right?

Dexter equipment is great stuff and worth every dollar.

  • Availability of Trailer Hub that has 6 on 5 inch Bolt Pattern
    The standard 6 lug bolt pattern for trailer is 6 on 5-1/2 inch like the part # 8-213-51UC1-EZ that you referenced. There isn't a 6 on 5 inch so my guess is what you have/need is actually a 6 on 5-1/2 inch hub like this one.

  • 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...

  • Replacement Galvanized Hubs For Dexter 8-213 on 5,200 lb Axle
    Dexter now uses hubs rated for 6,000 lbs for their 5,200 lb axles (as they are discontinuing that specific capacity), but the 6k rated Dexter 8-213 hub will fit the spindle on your 5,200 lb axle as they use the same bearings. The correct galvanized Dexter 8-213 hub for your 5,200 lb axle is the following: - Dexter Trailer Idler Hub Assembly # 8-213-51UC1-EZ If you want to verify you can do so by taking apart your current hub assembly and looking at the bearings themselves; wipe away the...

  • 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.

  • Is There An Idler Hub With 6 on 5-1/2" Bolt Pattern Which Will Fit a Mobile Home Axle?
    For a trailer using mobile home axles you will need the Trailer Idler Hub Assembly # 52655IEU to go with idler hubs. This will allow you to weld in a new spindle onto your axle tube which will give you the updated common sizes used on regular trailer axles. This has the same 6 on 5-1/2" bolt pattern as the Dexter Trailer Idler Hub Assembly 8-213- 51UC1 which we no longer carry. We do not carry a hub which fits the spindle used on mobile home axles since they were designed to be thrown away...

  • Recommended Replacement Wheel Stud For A Dexter Trailer Idler Hub Assembly # 8-213-51UC1-EZ
    The Dexter Trailer Idler Hub Assembly # 8-213-51UC1-EZ uses a 1/2" diameter x 2-1/4" long wheel stud. The closest option we offer to this size is part # 7-262 (1/2" diameter x 2-11/16"). If you have open ended lug nuts then you won't have any issues with the increased length.

  • 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...

  • 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 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.

  • 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...

  • 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...

  • 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.

  • 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...

  • 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...

    It looks like you have the Dexter Trailer Hub and Drum Assembly part # 8-174-5UC3 which is for old 6,000 lb to 7,000 lb axles that have the 5 on 5" bolt pattern. If that is the case then you can use the Trailer Idler Hub Assembly part # AKIHUB-655-6-K and the 10-10 Grease or Oil Double-Lip Seals part # RG06-090 to switch to a more common 6 on 5-1/2" bolt pattern. In order to confirm the above, you simply need to find the axle tag and look for the weight capacity and or serial number or...

  • 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"...

    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.

  • 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.
