Perfect fit for my 2002 Silverado Base 2wd with transplanted 5.3 Boost. If you want to go fast, you better know how to stop! I've paired them with an EBC Greenstuff seal and am more than happy with the result, especially considering the poor quality Power Stop rotors I've had before (which incidentally tend to warp excessively despite subsequent break-in). Manufacturer). Stay away from the cheap stuff, bite the bullet and go for these! Update, bought/installed November 2014, now March 2016β¦
