Was very pleased with these. They are well formed to the Titan Wheel wells, and installation was a piece of cake! No drilling involved at all. Simply either remove splash guards, or plugs if you don't have guards. Run screws into existing factory holes, and also supplied fender clips. Directions were very easy to follow, and can have a professional looking job, with the satisfaction of doing it yourself! I didn't purchase mine here, but have been told about this link where you can get them for $320.00 plus a $12.00 handling fee, FREE SHIPPING!
