These parts are for a 2010 Chevy Silverado, brand new pads and rotors. They may fit other years, up to buyer to determine this. The pads are Wagner ceramic and the rotors are better daily driver, but they are not drilled or slotted. Better brake parts for a typical daily driver, minus the shipping charges and tax. Never been installed. I was asked if these would fit a 4WD and my research says that they will fit.
