As a new buyer of automotive accessories I was impressed with the RockyParts mud flaps I ordered .they were easy to install and fit my 2007 Silverado perfectly. As a result of my tests, i determined that these mud flaps significantly reduced the amount of dirt and debris that kicked up onto my truck. The only downside was the price, but I believe the quality justifies the cost. Overall, I am very satisfied with my purchase and would recommend these to other Silverado owners..
