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

Built for Work & Adventure

We offer shipping to most countries around the world. Shipping times may vary depending on the destination country and shipping method selected at checkout. We typically process orders within 1-2 business days of receiving payment, and we will send you a tracking number once your order has been shipped.

Standard Shipping:
Our standard shipping option is available for most countries and typically takes between 7-14 business days to arrive, depending on the destination.

Express Shipping:
We offer express shipping to select countries. This shipping option typically takes between 3-7 business days to arrive, depending on the destination.

Customs and Fees:
Please be aware that some countries may charge customs duties, taxes, or other fees on imported goods. These fees are not included in our prices or shipping costs, and are the responsibility of the customer. We are not responsible for any delays or additional fees incurred due to customs clearance processes.

Delivery Time - Domestic

Typically, your package should reach you within 2-9 days of placing an order. 

The answer to this question depends on what shipping service is used or selected. Included shipping is most often done through USPS Priority or FedEx which is not a guaranteed service but estimated at 2-4 days depending on how far away from Utah it is traveling. For larger packages, we use FedEx/UPS GROUND or SUREPOST. These services are estimated at 3-5 days and 5-7 days respectively. 

We do offer expedited shipping options, but please remember that those estimations are not including the processing time, which is usually 24 hours or less except on weekends. However, those times can be affected by weather.

Delivery Time - International

Internationally, this depends on multiple factors such as destination, carrier and selected service. Our normal handling time is about 24 hours, except on weekends and Holidays when we are not in the office. With any shipping service, domestic or international, weather can cause delays in shipping. This type of delay is with the Carrier.

FedEx is a great option for most parts of the world. The fee includes clearance through customs and is pretty fast. In most cases it is around 3-5 days for delivery. Please note that you will still be responsible for any import taxes.

UPS is a great option to Canada, but quite pricey for other parts of the world. The standard service is estimated at about 9 business days. UPS offers faster services that can be delivered in as little as one day. If an expedited service is selected, please note that it is only guaranteed if UPS processes it through Customs. If you assign a different agent, the service is no longer a guaranteed service. There is an additional clearance fee as well as import taxes. 

***Please note that with all international shipments, import taxes are the responsibility of the buyer. 

We try to help when delays in delivery happen, but we cannot issue a refund on any portion of shipping unless the carrier approves a refund on shipping charges paid on our end.

Our fulfillment team does its best to adapt order changes when requested well ahead of the start of the following business day; however we are unable to guarantee that updates will be made prior to shipping.
