This is a pre-configured product; what you see in the photo is the design you will get.
Design: GMC AT4 mud flaps with AT4 logo with gloss black powder coat weight with red and white color backing
Application: REAR of the 2020 – current GMC 2500/3500 trucks with the factory trim guard in place. Does not fit Chevy trucks.
The 12″ mud flap will work only with the narrow splashguard. If you have the wider splashguard you will want to use our 14″ mud flap.
Mounting: DuraFlap mounting hardware is made of stainless steel where available. Other mounting products are made of anti-corrosive and rust resistant materials. Our drill-less mud flaps are custom designed to utilize existing factory holes and other mounting points available on your truck. Instructions included.
These mud flaps will be installed in front of the factory trim guards. The trim guards need to stay in place to avoid the gap in the lower panel behind the fender well.
Hardware: All required hardware and brackets are supplied with these mud flaps.
Serviceability: These mud flaps are pre-drilled and require no drilling of additional holes in your truck. Allows for easy & precise alignment.
Most orders without custom weights ship in 3-5 business days.
