GMC Sierra 1500/2500/3500 HD STEPBACK (3rd Gen) 2015+ Mud Flaps

**CLICK ON PHOTO FOR MORE PICTURES**

RokBlokz mud flaps for the GMC Sierra SRW Truck are CNC laser cut from a proprietary material specifically designed to endure the harshest environments. 

The unique blend of polymers in our mud flaps give them the specific characteristics that make them highly effective at protecting your truck.

Specifically the combination of extreme durability, flexibility, light weight, and rigidity that all come together to allow the flaps to extend out from the fender's edge enough to be effective, to hold their shape at speed and to block the most damaging kind of tire spray. RokBlokz mud flaps will bend, flex, give, and even scrape and drag without breakage. Doesn't matter if you're exploring the frozen tundra or the scorching hot desert, RokBlokz mud flaps will perform.

MADE IN THE U.S.A.

FITMENT:
Each RokBlokz mud flap set for the 3rd Generation 2015-2019 GMC Sierra comes with 4 Brackets and flaps (FRONT and REAR), stainless steel and rust resistant mounting hardware, and instructions for mounting.
