These Chevy/GMC dually mud flaps are a drill-less installation. These are approximately 20 inches wide by 3/8″ thick and come in two lengths. Standard length will hang 11″ below the rear fender, Long length will hang 13″ below the rear fender. It is best to measure your truck to figure out what length will work for you. Measure from the ground up to the painted surface of the rear fender and minus off the lengths (11, 13,) to determine how far off the ground the flaps will hang. We recommend to be at least 7″ off the ground to keep from backing up against curbs and parking guards.

We suggest ordering the dually mud flaps with the stainless weights across the bottom. The weights will help to prevent these wide mud flaps from taking a curl over years of highway driving.
You will also want to make sure your flaps are at least 2 to 3″ away from your exhaust pipe. If not, it will have to be moved. We do offer a stand off bracket to drill into the exhaust pipe that keeps the mud flap from touching it. Let us know when ordering if you need this.
