They fit my 2019 Silverado 1500 perfectly. I needed spacers for the new wheels because the brake calipers on the new Silverados were bigger. I bought 1.5 inch and they are great. It doesn't look huge or ghetto like, but it gives the truck a nice muscular look. The only problem was that I was stupid and thought it was four packs. Ok, I ordered a second set and it arrived the next day. For the price and quality I couldn't be happier.
