Installation Instructions

Tools Recommended: Phillips head screwdriver, flathead screwdriver (for prying clips), small wrench/socket set, drill (optional, if new holes are required).

Important Note: Installation is generally straightforward, utilizing existing factory mounting holes. However, some users have reported that rear flap mounting holes may not perfectly align with existing vehicle holes, potentially requiring minor adjustments or drilling new holes in the flap or vehicle body. Proceed with caution and ensure proper alignment before securing.

Step 1: Prepare the Vehicle

  1. Park the vehicle on a level surface and engage the parking brake.
  2. For easier access, it is recommended to turn the steering wheel fully to one side when installing front flaps, and remove the wheel for rear flaps if necessary, though often not required.
  3. Clean the area where the mud flaps will be installed, ensuring it is free of dirt and debris.

Step 2: Install Front Mud Flaps

  1. Identify the front mud flaps. They are typically marked or shaped to fit the front wheel wells.
  2. Position the front mud flap against the fender liner and body panel.
  3. Align the holes on the mud flap with the existing factory mounting holes on the vehicle.
  4. Secure the mud flap using the provided screws and clips. Do not overtighten.
  5. Repeat for the other front wheel.

Step 3: Install Rear Mud Flaps

  1. Identify the rear mud flaps.
  2. Position the rear mud flap against the fender liner and body panel.
  3. Carefully align the holes on the mud flap with the existing factory mounting holes on the vehicle.
  4. Attention: As noted by some users, the top two holes on the rear flaps may not perfectly align with existing body holes.
    • If holes align, secure the mud flap using the provided screws and clips.
    • If holes do not align, you may need to drill new holes in the mud flap to match existing body holes, or carefully drill new small pilot holes in the vehicle body if absolutely necessary and you are comfortable doing so. Ensure proper placement to avoid damage to vehicle components.
  5. Secure the mud flap using the provided screws and clips. Ensure a snug fit without deforming the flap.
  6. Repeat for the other rear wheel.

Step 4: Final Check

  1. Once all four mud flaps are installed, visually inspect each one to ensure they are securely attached and properly aligned.
  2. Confirm that there is no interference with tire movement or suspension components.
