I have a Super Duty with 324,000 miles; I only had to replace the rear fenders because I wasn't looking where I was going backwards :( I ordered them, only the rear ones because I thought they would last at least 324,000 miles longer and I haven't had any problems. The only what i had to make the job easier the back had to be lifted up and the wheels removed which made things a lot easier and they installed in about 5 minutes per side they fit perfectly! i have had husky products for about 22 years ( when Weathertech started hitting the market), but maybe I'll revisit the Husky for the next car.
