Yes, they are wheel adaptors that I believe are original to the vehicle.

Hey
I don't think those adapters are original. I think someone put on different rotors. Somewhere I saw there are two kinds of rotors that go on the one ton chassis. If you had a one ton pickup non daully the rotor assembly was not as offset
T. The dually front rotors were the same brake caliper wise. But the hat stuck out farther. It was so the front wheels tracked in the same place as the outside rear tire. You may want to check into that. I only say this because you got a lot of weight and force on those adapters. Not so much the outer wheelbearing. It's probably pretty close to the original tracking. My 325 does not have those. Could be the po had an issue and solved it with the adapters. These ten bolt rotors are not something you just pop into the parts store for. Maybe all he could get was the one ton pickup rotors. Everything would bolt up the same I think just the wheels would be inboard about 3 inches. Anyway. Good luck. DJ

That’s good information DJ. Thanks.
The PO had the entire front end rebuilt and He says he spent a lot of money doing so. Maybe the rebuild kit included these spacers/adapters. I’ve driven several thousand miles on this set up and have had all the wheel bearings examined with no issues. Unless you or someone else is adamant that this is unacceptable, I am comfortable as installed. Again, great information. Thanks for your interest and concern.

I would be curious to know the dimensions(width) of the replacement rotor/adapter and compare with the original. If someone with a front wheel off, could possibly post it and you can compare.
The original 5 stud front rotor assembly is to the best of my knowledge NLA. The Rotor has to be bought separately and the eight rusty bolts have to be removed to split the 2 components. It would make me wonder why that was not done on your rig, since the adapter is very expensive, versus just replacing the rotor, which I believe is part Number ACD 18A274A.
Confirmation of this part number from someone how has done it would be appreciated.

Hey.
I don t think there's much of a problem with your setup. I m just curious as to why he or she.... did it that way. Maybe it was easier to just buy the adapters than to try to split the thing apart. Be a whole lot easier. The only concern I'd have doing that would be weight. These things are heavy as a small dump truck. Hitting bumps drives a lot of weight onto the front suspension. Just me. Somebody out there got 2 10 bolt hats assemblies laying around anyway good luck on the ride. Remember to always paint t calipers red. Not only does it stop faster it increases mileage and.... it looks cool cool trumps all proof. Corvettes Audi's mustang's and chargers have red calipers...DJ

Are they aluminium spacers and are they fitted front and rear? I'd be interested in the part number.

What tires are you running on the coach? I know that spacers are sometimes fitted to resolve the known issue around metric tyres rubbing on the rears.

Keith Fossey in the UK (Keith is on the forum) was making spacers to push the wheels out towards the edge of the wheel wells (and better fill the wheel arches). May be this is for the same reasoning?
