Brand new, never installed 1/2" wheel spacers for 2011-2026 Chevrolet and GMC HD trucks with 8x180 bolt pattern.
The are made by Bora which is the best in the business. They are hub centric to avoid any vibrations and come anodized black.
My cost was over $400 + tax but sold the truck before I ever used.
If the like your stock wheels but think they stick in too far or need to change the offset, this is the solution
