I am not sure if that would work. That fitment was not tried. They are working on the front replacements as well. The 4 needed to be finished to allow for aftermarket flap installation.
They will not. The caps are designed specifically for the Sierra. The Sierra slash guards when removed leave a large gap to fill. The Silverado doesn't have that issue. But I would love to get you in some of the Gatorback no drill flaps. :)
They will not, the Sierra 2500 has much different angles on the body when they are removed. Gatorback was not able to get a finishing cap to work on the Sierra HD
Here is the 6 piece set. These parts are in bound to our warehouse and should be ready to ship in the next week. https://www.sharptruck.com/2019-2021-gmc-sierra-1500-finishing-caps-6-piece
They will not fit. Gatorback is working on getting a cap for the HD created. It should be done by the end of the year. If you go here, https://docs.google.com/forms/d/1Zmq-jNvCc00dTpAnCm4VlBu9GcFRrFZY1dWmJz9zT58/
We will notify you when it is ready to order.
No, they only work on the 1500. Gatorback is putting finishing touches on the caps for the Sierra HD trucks. If you go here, https://docs.google.com/forms/d/1Zmq-jNvCc00dTpAnCm4VlBu9GcFRrFZY1dWmJz9zT58/ you can sign up to be notified when these are ready to ship out.
Yes, you would use the 6 piece set, https://www.sharptruck.com/truck-hardware-fc003k-2. This will include the finishing caps for in front of the rear wheel.
