Rock Tamers Mud Flaps - RT34FR Review

Today we're going to take a look at the replacement hub for the Rock Tamers Heavy-Duty, Adjustable Mud Flap System for three inch hitches.Now, this part will replace the center hub on your Rock Tamers Heavy-Duty, Adjustable Mud Flap System. We do sell that system separately on our website. It's part number RT54FR.This hub is a forged aluminum construction, has a UV protected black matte powder coat finish to it. It is designed to slide onto the shank of your three inch ball mount or tow bar. If I put the ruler on, you can see there's your three inch by three inch dimension.The side arms do attach right here. Now the side arms, we do sell separately on our website, they're listed on this product page as a related product.

And it'll tighten down with the clamp bolts again, which are sold separately, they're part number ERT052, and this is for a quantity of one replacement hub.But that should do it for the review on the replacement hub for the Rock Tamers Heavy-Duty, Adjustable Mud Flap System for three inch hitches.

I have a F350 2021 Super Duty with the 3" hitch. Is there enough space to mount to directly to the 3" class 4 hitch without a ball hitch? CUrrently I have a 2" slide in hitch to a 2.5 to 3" sleeve.

It sounds like you're wanting to install this hub directly to the hitch receiver? If so, that will not work. This replacement hub has a 3 inch by 3 inch inner diameter, which is designed to fit around a ball mount or accessory shank that installs inside the receiver. The other diameter of the receiver is larger than 3x3, so the hub would not fit around it. If your 3 inch to 2-1/2 inch reducer sleeve has at least 1 inch of clearance, like shown in the diagram on the Rock Tamer # RT54FR product page, then this 3 inch hub would allow you to install the Rock Tamers on that sleeve.
