Corrosion Resistance for Marine Use

This trailer hub-and-drum assembly has a zinc coating that resists corrosion, making it ideal for use on your boat or snowmobile trailer. All GAL-DEX hubs and drums 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"

Cheap junk. One of the hubs was not properly coated. Will not recommend this to anybody. Cheap junk from China. Photos will be attached.




by:

Shipping was pretty fast and packaging nice and secure. The drums and brake backing assembly were a breeze to install without instructions. I was a bit surprised though that the back kit did not come with 4 new bolts to secure onto the flange. I used the old ones. The drum kit comes with new lug nuts though. I have no real complaints, I would definitely use etrailer again. Excellent pricing and quality. I installed these brakes the next day after receiving them. I used marine grease from autozone to pack the new bearings. The brakes are bled and adjusted as per the sticker on the kit...adjust til you cannot turn by hand and 10 clicks out. All that's left is to test drive it.

We had a break down on Saturday when we picked our boat up from storage. Went online and ordered the necessary parts to repair the trailer and forgot about it for a couple hours. Etrailer called to notify us that the selected parts would not arrive as hoped based on the shipping I had chosen. They went out of their way to locate the suitable parts and verify that they would arrive by the time I needed them so we could get the trailer repaired and back on the road. Thank you Etrailer for the excellent customer service!!! I look forward to my next order with you!




by:

Stripping down a 16 year old 21 ft. salt water use trailer - from end to end. The folks @ etrailer were very knowledgeable, and helpful in my decision making. From placing the order, to tracking the order, to the way the items were packed for transit. Other distributors could learn from these people; in regards to customer service, following up, both office and warehouse. Unloaded the products last night, nothing short, all quality in regards to their products, with great pricing. The installation videos are a big bonus, and something I'll be taking advantage of, during the restoration. Will follow up with picture, (before and after) when I'm done




by:

Everything purchased worked exactly as expected and continues to do the job I needed of them. I have and will continue to purchase all my trailer products from E-Trailer...

I'm just getting around to installing
my drums, thanks for promptly getting them to me, they look great!

I'm wondering if this product has the free backing feature or if I need to manually lock out the brakes when backing up. Any information is appreciated.




by:

High quality and very easy to install!




by:

Bought the galvanized drum brakes for a 6000# boat trailer used strictly in salt water. With rinse off after use they seem to be holding up pretty good.




by:

Excellent resources to help determine the exact parts I needed for my trailer project. Great product descriptions and videos. Competive prices and quick shipping! Thank you very much!




by:

I would highly recommend etrailer if they have what you need. These people really care about filling your order properly and followup with anything you order from them. They assume nothing!

This is a class AAA business to do business with.




by:

So far so good! Wish it would have come with new castle nut and washer. Fast delivery!




by:

I used these on my salt water boat trailer. The product works very well and have stood up to the salt water quite well.
I am happy with the results and ease of use.




by:

Perfect replacement for my old worn out Hub/Drum. I went with the galvanized becasue of use in saltwater.

Thanks E-Trailer.




by:

  • Can Electric Brakes be Added to a 5 by 10 foot Utility Trailer
    Yes they can, if you check out the link I attached you will see a page that has a guide on how to add electric drum brakes to a trailer. Basically you are going to need to know what spindle you have on your trailer so that you can determine what brake drum/hub would fit it and then build it from there.

  • New Hubs Do not Fit Over Brake Shoes On Trailer
    If the hub you are replacing has 8-247 stamped on it as you mentioned, the part # 8-247-50UC3-EZ, should be the correct replacement. You mentioned the hub will not fit over the brake shoes.

You will need to turn the adjusting star wheel to move the shoes in or out for adjustment. I have attached a video that shows how brakes are installed, and at about...

  • Solution for 2007 Keystone Springdale 249 5th Wheel Needing Replacement Spindle
    Since you need a new spindle too and installing spindles is a specialized job that usually costs more than just replacing an axle typically in your situation it's best to just replace the entire axle. This will be easier, more cost-effective and will give you all new axle components for both sides of the trailer. You are going to need to measure your current axles in a few places to get the correct one as we don't have access to what your numbers reference. You will need to measure from...

  • Recommended Replacement Hub/Brake Drum for Boat Trailer Axle
    I'd almost be willing to bet the farm that your inside bearing is actually a L44649 with an inner diameter of 1.063 inches. A typical 3500 lb axle will have a L68149 inner and a L44649 outer bearing. If that's the case, the Dexter # 8-247-50UC3-EZ galvanized hub/drum you looked at would work well for you. The hub includes the bearings, races, 10-19 grease seal, grease cap and lug nuts.

    For the price of replacement brake pads and shoes it's almost always a better solution to go ahead and just replace the entire brake assembly. And in your situation with the current condition of your assemblies I would strongly recommend you do that based on how much rust is there. In order to pick out assemblies you need to know the diameter of the assemblies and the width of the brake brake pads. I can tell by the pics you have the standard 4 bolt mounting flange.

  • What Would Cause Wheel Studs of Dexter Hub 8-247 to Sheer Off
    Sometimes with all the studs of a hub sheer off it's because one lug nut started to come loose which then caused others to work loose and with enough play the impact on the stud as the wheel turns eventually sheers off the stud. The replacement wheel studs you need for hub part # 8-247-50UC3 would be part # 7-262.

  • Will 3,500 lb Dexter Hub/Drum Fit 3,500 lb Axle that Had Oil Bath Setup
    Yes, the Dexter hub/drum part # 8-247-50UC3 does fit your 3,500 lb axle spindle and will work great. It doesn't require anything beyond install of the hub and packing with grease to convert to a grease hub also. The best grease is the Lubrimatic LMX Red Grease part # L11390.

  • Is 84656UC3-EZ 10 Inch Hub Drum a Direct Replacement for Dexter 8-247
    You are correct. The # 84656UC3-EZ hub/drum you'd looked at with the 6 on 5-1/2 inch bolt pattern uses the same L44649 outer/L68149 outer wheel bearings and 10-19 grease seal as the 8-247 hub/drum like the # 8-247-50UC3-EZ you'd looked at. Since the inner and outer bearings and ID of the grease seal match up, the # 84656UC3-EZ would be a compatible replacement.
