Good question, Dale!

It took me a few minutes of back and forth between the two Hydrastar disc brake kits to figure it out, but the only difference is that # HYD44VR uses all Dacromet coated parts and the # HYD74VR uses mostly Dacromet coated parts, but stainless steal calipers. Other than that, they are exactly the same.

I see you ordered the full Dacromet # HYD44VR option and it will work perfectly fine with your 5th wheel. Have you done this kind of install before?
