After spending several hours cleaning my white Silverado of tar and rail dust, I decided fenders were a must. I chose them after researching on the internet. It only takes a few minutes to fit to any wheel arch and the fit is great! Don't be a wimp and drill a 1/8" hole for the third bolt on the rear wheels. The extra bolt makes a HUGE difference. There are no wheels/tires to remove. Just use a socket wrench with a torx bit ". If you do this, the OEM tires will have enough clearance... and the cut side will be obscured by the fenders anyway. It's a minor inconvenience, but certainly something anyone can easily do. End of the wrench to hold onto. Mine were slightly misaligned but they snap when you tighten them they look OEM which I prefer and they seem very sturdy I am very happy.
