About this part
Pocket Fender Flares, fitment-checked
Riveted pocket styling for the 2020-2026 Sierra HD, with a simulated bolt-on face that reads as off-road hardware rather than a trim strip. Fitment covers Sierra 2500 HD and 3500 HD in 4WD and RWD, from Pro and SLE to Denali Ultimate. The flares extend 2 inches with a 6.5-inch height. Dually models are excluded.
The riveted, simulated bolt-on face is what separates this set from a smooth flare — it matches the look of aftermarket bumpers and steps on an HD truck. Fitment runs the 2020-2026 Sierra 2500 HD and 3500 HD in both drive configurations, including AT4 and AT4X. The flare extends 2 inches with a 6.5-inch height, and it mounts using factory points, so there is no drilling and no permanent modification. Tri-blend ABS handles impact and sun exposure, and the surface takes paint. Dually models are not part of this application. A downloadable installation guide is available.
