I have a set of four hub centric wheel spacers I bought from Fred Goeske. They are 1.5in adapters. They bolt on to current hub, and provide its own. It's a 6 Lug to 6 Lug. Was on a silverado for less then 1000mi. Its a great product with superb quality, beats anything else on the market. Selling due to swapping out wheels. I had bought some with wrong backspacing, company wouldn't take back wheels at first, then after a few complaints they changed there mind for an exchange which is why I'm selling them. Pictures are available if you would like to see. $300 obo
