RokBlokz Mud Flap Kit for 2020+ Chevrolet Silverado 2500HD & 3500HD: Ultimate Protection and Style

Your 2020+ Chevrolet Silverado 2500HD & 3500HD is built for tough jobs and rugged adventures, but its large, aggressive tires can kick up mud, rocks, and road debris that damage your truck’s paint and undercarriage. The RokBlokz Mud Flap Kit offers the perfect solution, delivering unmatched protection and durability while enhancing your truck’s aggressive stance.

Premium Materials for Maximum Performance

Unlike traditional rubber or plastic mud flaps, Rokblokz flaps are CNC laser-cut from a proprietary polymer blend, offering an ideal balance of flexibility, rigidity, and impact resistance. They won’t crack in freezing temperatures, warp in extreme heat, or break under stress—making them perfect for off-road trails, heavy-duty towing, and daily driving alike.

Sleek Fender Trim Cap for a Clean Finish

To complement the Silverado’s bold design, this kit includes the RokBlokz Fender Trim Cap, a precision-fit piece designed to replace the OEM splash guard trim. This addition creates a seamless, polished look while ensuring your truck maintains its factory lines and aerodynamics.

Key Features:

✔ Durable & Flexible Material – Resists cracking, warping, and fading
✔ Enhanced Protection – Blocks rocks, mud, and road spray from damaging your truck
✔ Sleek Fender Trim Cap – Provides a clean, finished look after removing OEM splash guard trim
✔ Easy Installation – Uses factory mounting points for a hassle-free setup
✔ Built for Any Environment – Performs in extreme cold, heat, and rough terrain
✔ Made in the USA – Designed and manufactured for top-tier quality
