Rough Country Mud Flap Delete Kit for GMC Sierra 2500HD/3500HD (2020-2026) — Front & Rear Tri-Blend ABS, Adds Tyre Clearance

Rough Country’s Mud Flap Delete Kit replaces factory mud flaps on 2020–2026 GMC Sierra 2500HD/3500HD trucks for a cleaner wheel-well appearance and extra tire clearance. This full front-and-rear kit is engineered to cover the openings left behind after mud-flap removal, delivering a seamless, factory-finished look while increasing space for larger tires and aggressive offsets. Made from a UV-stable Tri-Blend ABS material, the panels are built to resist fading, cracking and surface wear so the truck maintains a smooth profile over time. The set ships ready for at-home installation and can be returned to the original configuration if needed.

How does the delete kit improve the truck's appearance and clearance?

The kit fills the void left by factory mud flaps so you get a streamlined, finished wheel-well without unsightly gaps or exposed mounting points. Removing the flaps also frees up several millimeters of clearance around the tire, useful for larger wheel-and-tire packages or more aggressive suspension travel.

• Smooth, gap-free coverage where factory flaps were removed.
• Provides additional room for wider tires and aftermarket wheels.
• Makes the truck look cleaner and more modern from the side and rear angles.

Is installation something I can do at home, and what tools are needed?

Yes — the kit is designed for DIY installation and usually takes about one hour. Minimal cutting of existing material is required, and the job uses common hand tools plus a metal-cutting saw for trimming. Clear, prepared painted surfaces and follow fitment steps to achieve a factory-grade finish.

• Estimated install time: ~60 minutes for both front and rear.
• Tools: common hand tools and a metal-cutting saw for minor trimming.
• Can be reversed to stock if you keep the original mud flaps and hardware.

What materials and durability can I expect from the Rough Country delete panels?

The panels use a Tri-Blend ABS formulation that’s UV-protected to slow fading and maintain color and texture under sun exposure. The material resists rust and cracking better than metal alternatives and is suited for road debris, normal cleaning, and seasonal use. Rough Country backs the product with a limited lifetime replacement warranty against manufacturer defects.

• Tri-Blend ABS construction for toughness and flexibility.
• UV protection to reduce sun fading and surface breakdown.
• Limited lifetime replacement warranty for structural and workmanship issues.
