Are Rock Tamers 2 and 2-1/2 Inch Hubs Interchangeable

Question

Question:

I have a set of rock tamer mud flaps with the 2 1/2inch hub but want to know if I bought the 2inch hub if everything would attach. That way I can have both hubs and interchange the rest of the parts?

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!

I have a 2 1/2 inch hitch ordered a 2 1/2 inch hub. How do I know if it’s going to securely fasten my rock tamers to the hitch? I also ordered a 2 1/2 inch hub because I thought I had a 3 inch hub as the bolts were not long enough to reach my 2 1/2 inch hitch. Please help I gotta get back on the road.

@OnA Hello On A, Yes, if you have a 2-1/2" hitch and you’ve ordered the 2-1/2" # ERT057 Rock Tamers hub, that should be the correct match. The hub clamps securely around the shank of the ball mount that slides into your 2-1/2" receiver. If the previous bolts were too short, it could be because the hub was oversized (possibly for a 3" hitch), and now the new 2-1/2" version should fit snugly and allow proper bolt engagement. Where are you headed once you get back on the road?

Hey Kelly! It looks like our information shows your tire size is 205/75R14. However, I would double check the tire size on the side of your existing tires to see if that matches. Are you looking for just a tire or a wheel and tire combo? Assuming you…

Answer 6

Some wiggle is actually pretty normal. It's not recommended to have a pin that fits exact to the hitch pin hole as it would make it very difficult to line up the hitch pin and the hole in the shank of the hitch accessory.
