Buying Guide: Fender Flares For Dually-Equipped Trucks
What should you consider when choosing fender flares for a dually truck?
- Fitment: Confirm whether the flare set is designed for duallies or if it targets single-rear-wheel configurations. Mismatches can cause rubbing or improper gaps.
- Material: Polypropylene (PP) is common for durability and flexibility. Avoid cheaper ABS if you want UV resistance and long-term shape retention.
- Finish and style: Textured black, pocket rivet, or smooth rivet styles affect appearance and maintenance needs. Consider your vehicle’s trim and color.
- Coverage vs. clearance: Larger tires require wider coverage, but ensure the flares don’t interfere with wheels, suspension, or mud flaps.
- OEM vs aftermarket: OEM-style flares tend to fit tightly and retain factory aesthetics; aftermarket options can offer broader fitment and style options.
Installation and maintenance tips
Follow the manufacturer’s instructions for alignment and mounting. Regularly inspect mounting points for loosening hardware and check for paint chipping caused by flare edges.
