Ok so I originally bought 4 half moon mud flaps from Sharp truck for my 2017 GMC Sierra 1500. What I needed to purchase was the full sized rear. one phone call and I had the correct bracket and flap delivered. Great Customer service and will purchase again in the future.
The mud flaps did not fit the brackets and to modified as well as hanging freely I did not like! SO we screwed them to fender wells. If you like them swing freely they can hit and rub the tires no thanks.
The brackets had to modified due to the fact the holes that hold the brackets to the body of the truck were out of linement! Which made the mud flaps hang over the outside by over an inch. They looked nasty!
Fit and finish were great. Stainless steel fasteners were perfect. I really like the looks of the flaps. Set off the truck and keeps the mud off the factory running boards. No more dirty back of pants legs. I recommend these for full functionality and great looks.
