2Pc 6x5.5 Hub Centric Wheel Spacers 13mm For Chevy GMC 1500 Silverado 6x139.7

Does not fit stock 2019+ Chevrolet Silverado Trail Boss black 18" wheels. These spacers match up perfectly with the hub and lugs, but the center ring is slightly too wide in diameter to fit inside the wheels. I had to take these spacers to a machinist, along with a 5th wheel (which I use as my spare and run a 5 tire rotation every 5,000 miles for my truck), for them to be trimmed in order to fit. That ran me $129 in addition to the $131 ($65.50×2 so I could have 4 spacers), thereby doubling the cost of these. I'm now looking into having them recoated to prevent corrosion associated with having 2 different bare metals in contact with each other and exposed to the elements. Therefore, I've already paid double what this company charges for them and still have more cost to sink before I can use them. If you have this truck and wheel setup I do not recommend these spacers. They might work with other OE wheels, but I have no way of checking. Buyer beware.
