Review on ECCPP 1.5-inch 8 Lug Wheel Spacers 8x6.5 to 8x6.5 130mm CB | Silverado, Sierra, Yukon HD | Fits 2500 3500 HD, 1500 2500 3500 with 14x1.5 Studs by Jonathan Brendemuehl

You jumped in half! Don't buy this! This brand has changed in recent years and now uses inferior aluminum. The second set I bought shows a lot of stress and pressure points on the outside of the gasket under each nut after it's fully tightened. In addition, the nuts are no longer properly hardened and the threads are deformed after they are fully tightened.
