Description

Product Description:
These Chevy/GMC dually rear mud flaps feature a drill-less installation and are built for long-term durability and protection. Measuring approximately 20 inches wide by 3/8-inch thick, they are available in two lengths:

Standard Length: Hangs 11 inches below the rear fender
Long Length: Hangs 13 inches below the rear fender

To choose the correct length, measure from the ground up to the painted surface of your rear fender, then subtract either 11 or 13 inches to determine how far the flaps will hang from the ground.
We recommend at least 7 inches of clearance from the ground to help avoid contact with curbs and parking barriers.

Application:
Fits the REAR of all 2015 – 2019 Chevy and GMC Dually trucks.

Mounting:
DuraFlap’s mounting system is drill-free, utilizing existing factory holes and attachment points. Brackets are made from stainless steel or aluminum, while all other mounting components are anti-corrosive and rust-resistant.

Hardware:
All necessary hardware and brackets are included for a secure, hassle-free installation.

Serviceability:
These flaps are pre-drilled to ensure easy and precise alignment with no additional drilling required. Engineered for dually truck owners who want maximum protection for their vehicle and anything they’re towing.

Recommendations:
We highly recommend upgrading to stainless steel weights across the bottom of the flaps. These weights help maintain flap shape and reduce curling from long-term highway driving.

Ensure your mud flaps maintain at least 2–3 inches of clearance from your exhaust pipe. If not, the exhaust may need to be repositioned. We offer an optional stand-off bracket that mounts to the exhaust pipe to prevent contact—please let us know if you’d like to include this with your order.
