Good product but expensive. Written Instructions are not very clear. Read the instructions and watch the youtube video before you start the install. Good coverage with 35x12.50 tires. Adjusted the hole positions slightly to position the flap out further to provide more coverage.
I have a 2000 Ford F250 super duty and these Gatorback 12"x23" Powerstroke Mud Flaps are perfect. Got them on really easily and they look good and preform great. Drove through lots of mud and the back end of my truck stayed totally clean thanks to the new flaps.
These are the best I have ever seen on the market. Material is heavy duty yet flexible and the installation is very easy which took very little time. Just not sure for the amount of money they didn't have black washers and bolts vs. bright silver. I painted all of mine so they did not stand out.
