Exact replacement… Awesome
As always Amazon is the best. Fast shipping. Arrived exactly when they said it would. The rotor was an exact match to the original. AC Delco has OEM replacement parts for most if not all vehicles. Chevrolet, GMC Cadillac vehicles for sure. You can never go wrong when choosing AC Delco. I highly recommend this product and all AC Delco products for your replacement needs. The installation was easy. The new rotor fixed the vibration problems I was having. Perfect fit, same thickness and smoothness. Overall excellent quality product.
