About this part

2-Inch Pocket Fender Flares, fitment-checked

Pocket flares for the 2020-2026 GMC Sierra 2500 HD and 3500 HD in 4WD and RWD, adding 2 inches of coverage with a 6.5-inch flare height. Dually models are not compatible — check your rear axle before ordering. Installation uses factory mounting points with no drilling, and a downloadable installation guide is available. Shipping weight: 18 lb.

This set works across the 2020-2026 Sierra 2500 HD and 3500 HD in rear- and four-wheel drive, covering Pro, SLE, SLT, AT4, AT4X, Denali, and Denali Ultimate. The single hard exclusion is dually models — the dual-rear-wheel fenders are a different shape and this application does not cover them. Coverage measures 2 inches outward with a 6.5-inch flare height, which fits an HD running a wider tire. The riveted face installs at factory mounting points without drilling, and the tri-blend ABS shell is UV-protected and paintable to your truck's color code.
