91 f350, i want the biggest fender flares out which im guessing is the cut outs?? is there any actual cutting involved with installing them,or can they just be screwed to the body of the truck?? ive got 9" of lift and 38.5's so not worried about any clearence issues so....

 

Yes, you have to cut out the fender a bit with the cut outs. There is another option that is similar to the cut outs, called pocket flares. The pockets have almost the same coverage, the bolt look and do not require trimming the sheet metal.

 

ok ill look into the pocket flares ,thnx
