Video Transcript for Review of Rock Tamers Mud Flaps - Replacement Center Hub - ERT057

Hello, everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this replacement hub for the Rock Tamers heavy-duty adjustable mud flap system for 2 1/2 inch hitches. Now this part here will replace the center hub for the Rock Tamers heavy-duty adjustable mud flap system. That system we do sell separately on our website, and it's part number ERT00110. I did wanna pop up an insert just to show you the system that we're talking about, if you notice, you can see this part is in the very middle there, that'll slide onto the shank, and you see the mud flaps on each side. So the Rock Tamer fully adjustable mud flaps, they're heavy-duty rubber mud flaps that'll slide onto your ball mount or tow bar and they adjust horizontally and vertically for a custom fit on your vehicle.

This part here is for just the hub portion that the side arms it'll attach to and it allows you to slide mud flaps onto the shank of your 2 1/2 inch ball mount or tow bar. Now the side arms that go right in here on each side, now those are not included. They are sold separately. They're part number ERT039 and ERT040. And then this hub will tighten down onto your shank with the clamp bolts, which go right in here.

And again, they're not included. We sell those separately, part number ERT052. This this for a quantity of one replacement hub. And then just to give you the measurement, this fits on 2 1/2 inch by 2 1/2 inch hitches, so you can see the center portion is 2 1/2 inches by 2 1/2 inches. But that should do it for the review on the replacement hub for the Rock Tamers heavy-duty adjustable mud flap system for 2 1/2 inch hitches..

Once again etrailer to the rescue. I moved from a 2” to a 2-1/2” hitch setup and they had all the parts I needed to get the job done efficiently and very cost effectively. Not to mention prompt delivery.

Thanks!

Great buy, attractive and effective and easy to store and install on my hitch. No rock damage since purchasing it.



by:

I went from a 2" receiver hitch to a 2.5" and I bought this worked really good for the new hitch definitely would recommend this product



by:

Product is direct replacement



by:

Easy change over from the 2.0" to the 2.5"
Perfect
fit and quality product.

As always etrailer came through with flying colors. Replacement hub is already mounted - no issues. Only complaint with this order was having to deal with an etrailer rep that supports the St. Louis Cardinals (I’m from Chicago). Thank goodness she has a great sense of humor. Thank you etrailer... and Sharon O.

So much better than dealing with a 2” shank w sleeve. Thanks etrailer.



by:

The replacement hub for the 2 1/2 inch hitch is a must, works great.

Still happy with the products, they work great.



by:

Works just like it’s supposed to!



by:

Oh my goodness! The best part was customer service. She knew exactly what I needed and where it was in their site. Very helpful and knowledgable.
I had to convert my 2" hitch to a 2 1/2" to tow my travel trailer after buying a new pickup. The part is an original brand name part for the 'Rock Tamer'.
Purchasing the parts cost a fraction of the cost of replacing the entire items.
No problem swapping out, no modification needed.



by:

Just the item to update to the new larger receivers.

Great. no problems at all.



by:

I needed one for my 2" hitch and my 2 1/2" hitch. I would have thought it would have come with the bolts that secure it to the hitch but I will get some at the local hardware store. I do really like the mud flaps.



by:

Already had the Rocktamers, just needed to upgrade to 2 1/2" hitch for my new F350. Quick shipping and fair price. Thanks!



by:

I upgraded from a 2" receiver to a 2.5". I simply bought this larger sleeve to accommodate the larger receiver. Works great!



by:

Very happy with them. Easy to use and durable. I bought an extra hub so I'd be able to use it with both 2" and 2.5" shanks, depending on what I was towing. Glad I bought them.



by:

When I upgraded our truck didn’t take into consideration hitch size. I’m glade this was available. Thanks eTrailer for helping me out.



by:

Always excellent service from the folks at etrailer. Extremely friendly and knowledgeable. I wish all online venders had their business attitude. Thank you again



by:

Super fast shipping!!

Etrailer. Great company.



by:

The replacement hub fit perfectly and was easy to install.



by:

We found a NIB set of RockTaners on Marketplace for a great price. The hub on that set was too small so we ordered this part. It works great!

I do not tow my boat without it, it works that well. Today’s fiberglass bass boats cost a small fortune so having the Rock Tamers is added insurance to protect my poor choice of investment, haha



by:

Exactly what I needed when I got my HD truck.



by:

Quality stuff

Received just as described. Perfect. Thank you

Great product and price. Purchase arrived quickly.

    We certainly do have a replacement 3 inch hub for the Rock Tamers Mud Flap systems. You'll need part # RT34FR.

  • Will the Rock Tamers Mud Flap System Work with a Weigh Safe True Tow WD System
    The Replacement Hub for Rock Tamers Heavy-Duty, Adjustable Mud Flap System for 2-1/2" Hitches, part # ERT057, is designed to fit around 2-1/2" accessories. Your Weigh Safe True Tow WSWD8-2.5 has a shank for 2-1/2" shank, so fitting around the shank will be no problem. As for having enough space, that is something that I could not confirm since I could not get the measurements of your shank. However, if there is a distance of at least 1" between the lip of your receiver and the closest...

  • Are Rock Tamers 2 and 2-1/2 Inch Hubs Interchangeable
    Yes, both the 2 inch hub, # ERT034, and the 2-1/2 inch hub, # ERT057, attach to the same side arms, # ERT039 and # ERT040, and use the same clamp bolts, # ERT052. So the 2 inch hub will work with the same parts currently on your 2-1/2 inch system!

  • Does The Rock Tamers Heavy-Duty, Adjustable Mud Flap System ERT00110 Require a Ball Mount?
    Yes, the Rock Tamers Heavy-Duty, Adjustable Mud Flap System for 2-1/2" Hitches # ERT00110 does require a 2-1/2" Ball Mount # BWBMHD30210 with at least 1" of space for the Hub # ERT057 to fit without any gussets. It will also fit with 2-1/2" adjustable ball mounts as long as you have the 1" space for the hub. I recommend using a BOLT Trailer Hitch Receiver Lock # BL7023582 to secure the assembly in your receiver. This lock will key to your trucks ignition key so there is no need for carrying...

  • Rock Tamers Needed For A 2024 GMC Sierra 2500 With Blue Ox WDH
    Hi David, Rock Tamers require an inch of space on the ball mount shank in order to mount. If the portion of the shank exposed where you'll be installing the Rock Tamers is 2" x 2" then you'll want # ERT00108, for 2.5" x 2.5" you need part # ERT00110. The WDH shank should be what you're going off of so 2" is more likely what you'll need. Rock Tamers offers a bolt-on heat shield # RT76FR to help protect the flaps from the exhaust. If you ever change out the WDH with something that has a...

  • Hitch Pin Hole Distance On Blue Ox Adjustable Ball Mount # BLU89XR For Rock Tamers Mud Flap System
    The Blue Ox Adjustable Ball Mount # BLU89XR has a distance of 4-11/16" from the center of the furthest receiver hitch pin hole to the weld on the tube. The shorter hole is 3-7/16" from the center of the receiver hitch pin hole to the weld on the tube. Since the Hub # ERT057 for the Rock Tamers Heavy-Duty, Adjustable Mud Flap System for 2-1/2" Hitches # ERT00110 requires 1" of space you will need to measure the distance from the center of the hitch pin hole on your receiver to the collar...

  • What Does Replacement Hub for Rock Tamers Fit
    The Replacement Hub # ERT057 you referred to attaches to Hub Arms # ERT039 and # ERT040 which are part of the Rock Tamers Heavy-Duty, Adjustable Mud Flap System for 2" Hitches # ERT00108. So if you have Rock Tamers model # ERT00108 then Replacement Hub # ERT057 will work for you but this is the only 2" system I can confirm the hub will work on. Keep in mind you will need to tighten the hub with Clamp Bolts # ERT052.

  • Rock Tamer Hub Mounting Options
    Thanks for the pictures! I see what you are talking about. The collar on the OEM hitch receiver will not allow you to mount an accessory on the outside. I do have a solution for you that will allow you to use the Rock Tamer System with any of the three sizes of ball mount options you have available depending on which one you use. The Replacement Hub for Rock Tamers Heavy-Duty, Adjustable Mud Flap System for 2-1/2" Hitches item # ERT057 fits around the actual ball mount not the receiver...
