I bought these full metal wheel spacers for a 2008 Chevrolet 3500. PRO: The price is cheaper than anywhere else on the web. CONS: I had to cut off the "hub ring" that was welded onto the spacer. This small ring had a weld that prevented the seal from slipping over the hub. The thickness of the "hub ring" would also prevent the outer wheel from fitting properly onto the spacer. SOLUTION: I used a flathead screwdriver and a hammer to "pound" the ring out of the spacer. I then used a 3" cutting wheel to remove the rest of the weld/material.
