3. Setup and Installation
Installation of these running boards is designed to be straightforward with no drilling required for most applications. All necessary mounting hardware is included.
- Preparation: Park your vehicle on a level surface and engage the parking brake. It is recommended to have a second person assist with the installation to ensure proper alignment and safety.
- Thread Cleaning: Before attaching the brackets, it is highly recommended to clean out the factory threaded holes on your truck's frame. An M8x1.25 tap can be used to clear any debris or rust, which will significantly ease the installation of bolts.
- Bracket Installation: Attach the mounting brackets to the designated points on your vehicle's frame using the provided hardware. Do not fully tighten bolts at this stage.
- Running Board Attachment: Carefully position the running boards onto the installed brackets. Secure them with the remaining hardware, ensuring proper alignment and spacing.
- Final Tightening: Once both running boards are correctly aligned, progressively tighten all bolts to the manufacturer's specifications. Double-check all connections for security.

5. Maintenance
Regular maintenance will help prolong the life and appearance of your running boards.
- Cleaning: Wash the running boards regularly with mild soap and water to remove dirt, road salt, and other contaminants. Avoid abrasive cleaners or harsh chemicals that could damage the powder-coated finish.
- Inspection: Periodically inspect all mounting hardware for tightness. Re-tighten any loose bolts to prevent rattling or instability. Check the running board surface for any signs of wear, damage, or corrosion.
- Finish Care: While the product features an anti-corrosion primer and powder coating, prolonged exposure to harsh environmental conditions (e.g., road salt, extreme UV) can affect the finish over time. Address any chips or scratches promptly to prevent moisture ingress and potential corrosion.

6. Troubleshooting
If you encounter any issues with your running boards, consider the following:
- Loose or Rattling Boards: Check all mounting bolts and ensure they are securely tightened. Over time, vibrations can cause bolts to loosen.
- Paint Flaking or Corrosion: While designed for durability, environmental factors can impact the finish. Ensure regular cleaning and inspection, especially in areas exposed to road salt or harsh weather. Minor chips can be touched up to prevent further damage.
- Difficulty with Installation: Re-verify vehicle compatibility. Ensure all factory threads are clean and free of obstruction. A second person can greatly assist with alignment during installation.
