I had the Bushwhacker extenda flares on mine for 4 years. In a nut shell there junk. ! Do not waste your money. !
1. The little rubber strip that is supposed to stop the flare from rubbing through the paint fails in time and the paint get rubbed through to the bare metal in areas eventually.
2. If you spend anytime on bush roads etc. brush and whatever other road hazards will tear them off the truck, and break the plastic at the same time. These flares are not held on by much in the first place, so it takes very little contact with brush to tear them off and break them. I lost count how many times mine were torn off, usually I never new it until someone handed it to me.
3. And probably most importantly. Road crud builds up in behind the flare betwween it and the body and settles to the lowest point. Being abrasive it wears through the paint and causes rust.
I sent my Bushwhackers to the dump. My truck is patriot blue and silver like Serria Rams. I had all the silver done in Linex including all around the wheel wells so it looks like I have flares. I would highly recommend this approach.
