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 2016. Matched with a set of EBC pads and now I have to replace the rotor again. I've practically used up the slots on these things and am very disappointed that they didn't even last a full year and a half. I never expected them to last as long as the original equipment given the performance of this product, but come on, that's too much. I will look for SSBC next, hopefully they make a product that works AND lasts.
