Key Product Information
Additional Information
| SYMPTOMS | Stone chips and paint damage behind the wheel arches; heavy road grime along the rocker panels and lower doors; spray thrown onto a towed trailer or following vehicle. |
| TROUBLESHOOTING | If a flap contacts the tire, confirm it is mounted at the correct wheel position and that the vehicle does not have oversized tires or a lift beyond the design range. If a flap sits crooked, loosen the fasteners, realign and retorque. Recheck fastener tightness after the first few hundred miles. |
| INSTALLATION | Clean the area behind the wheel opening. Turn the wheel for access. Align the flap with the existing factory mounting points and secure it with the supplied hardware. No drilling is required on no-drill applications. Repeat for the opposite side and verify clearance through full steering and suspension travel. |
| MAINTENANCE | Rinse with the rest of the vehicle. Periodically confirm fasteners remain tight, particularly after off-road use or winter driving. |
| GENERAL_NOTES | Fitment assumes factory ride height and original tire size. Lift kits, leveling kits or oversized tires can change clearance. |
| FAULT_CODES | |
| REPLACEMENTS | Replaces factory mud flaps or splash guards where equipped, using the original mounting locations. |
