3. Installation Guide
The SERBNOPG Metal Upgrade Kit is designed for direct replacement of existing parts. Follow these general steps for installation. It is recommended to refer to your RC car's original manual for specific disassembly and assembly procedures if needed.
3.1. Preparation
- Ensure your RC car is powered off and the battery is disconnected.
- Gather necessary tools, such as small screwdrivers and pliers.
- Work on a clean, well-lit surface to prevent loss of small parts.
3.2. Replacing Swing Arms and Steering Cups (Front)
- Carefully remove the front wheels and any associated body panels to access the suspension components.
- Unscrew and detach the original plastic front swing arms (upper and lower) and steering cups. Note the orientation and placement of all screws and pins.
- Install the new metal front swing arms and steering cups, ensuring all pivot points and linkages are correctly aligned.
- Secure the new components using the provided screws or the original fasteners if compatible and in good condition. Do not overtighten.

3.4. Final Checks
- Once all new parts are installed, gently move the suspension components to ensure smooth operation and no binding.
- Double-check all screws and fasteners to ensure they are tight but not overtightened.
- Reattach wheels and body panels.
4. Maintenance
To ensure the longevity and optimal performance of your metal upgrade parts, regular maintenance is recommended:
- Cleaning: After each use, especially in dirty or dusty conditions, clean the metal components to remove dirt, debris, and moisture. Use a soft brush or compressed air.
- Inspection: Periodically inspect all metal parts for signs of wear, bending, or damage. Check screws for tightness.
- Lubrication: While not always necessary for these specific parts, if any pivot points or moving joints show signs of friction, a small amount of RC-safe lubricant can be applied. Avoid over-lubrication, which can attract dirt.
- Storage: Store your RC car in a clean, dry environment to prevent corrosion of metal parts.
5. Troubleshooting
If you encounter issues after installing the upgrade kit, consider the following:
- Binding or Stiff Movement: Ensure all screws are not overtightened. Check for any misaligned parts or debris obstructing movement.
- Loose Components: Re-check all fasteners. If a screw repeatedly loosens, consider using a thread-locking compound (blue Loctite, for example) specifically designed for small metal screws.
- Unusual Noises: Investigate the source of the noise. It could indicate friction, a loose part, or incorrect assembly.
- Part Does Not Fit: Double-check the compatibility of the kit with your specific RC car model. Ensure you are using the correct part for the correct location (e.g., front vs. rear, upper vs. lower).
