Review on Dynofit 2015 2019 Expedition One Piece Anti Rusting by Brian Unruh

These replacement nuts are great quality, they were used on the 2016 F-150 xlt crew cab, do yourself a favor and get rid of the original nuts that Ford fitted two pieces because one day you will run into problems trying to take them off and it's never the right time to do it. This is a one piece 21mm head to attach or detach. They fit perfectly and look very sharp over time just tell how they hold up to rust or corrosion I don't know yet but they seem to have a nice chrome finish. Good luck with your decision.
