Compatibility: Yikong 1/7 Rear Axle DF7 Desert Fighter RC Crawler.
Material: High-quality Aluminum Alloy.
Included Components: 1 x Link Lifter (as described in product details).
Setup and Installation
Before beginning installation, ensure your Yikong 1/7 Desert Fighter RC Crawler is powered off and stable. It is recommended to have a clean workspace and appropriate small tools (e.g., hex wrenches, small screwdrivers) for RC model assembly.
- Identify Existing Part: Locate the rear upper link mount base on your RC car's rear axle. This is the component that will be replaced.
- Remove Old Part: Carefully unscrew and remove the existing rear upper link mount base. Keep track of all screws and small parts.
- Position New Part: Place the SERBNOPG Aluminum Alloy Rear Upper Link Mount Base Riser into the designated position on the rear axle. Ensure proper alignment with the mounting holes.
- Secure New Part: Use the original screws (or compatible screws if provided with the upgrade part) to securely fasten the new aluminum alloy part. Do not overtighten, as this can strip threads.
- Reattach Links: Reconnect the upper links to the newly installed mount base. Ensure all connections are firm and allow for proper suspension movement.
- Final Check: Verify that the new part is securely installed and that all links are properly attached. Gently test the suspension movement to ensure no binding or obstruction.

Operating Considerations
Once the SERBNOPG Aluminum Alloy Rear Upper Link Mount Base Riser is correctly installed, your Yikong 1/7 Desert Fighter RC Crawler will operate as usual. This upgrade part is designed to provide increased durability and structural integrity to the rear axle's upper link mounting point. No specific operational changes are required for the RC car's controls or driving style due to this component.
Maintenance
Regular maintenance helps ensure the longevity and performance of your RC car and its upgrade parts.
- Cleaning: After use, especially in dusty or dirty conditions, clean the part to remove any accumulated dirt, mud, or debris. A soft brush or compressed air can be used.
- Inspection: Periodically inspect the link mount base for any signs of wear, bending, or damage. Check that all screws remain tight. If any damage is observed, consider replacement to maintain optimal performance and prevent further issues.
- Fastener Check: Ensure all screws securing the link mount base and the suspension links are properly tightened. Loose fasteners can lead to poor performance or component failure.
Troubleshooting
If you encounter issues after installing the SERBNOPG Aluminum Alloy Rear Upper Link Mount Base Riser, consider the following:

- Loose or Wobbly Part:
- Ensure all mounting screws are securely tightened. Avoid overtightening.
- Inspect the mounting holes on both the RC car and the upgrade part for any damage or manufacturing defects.
- Suspension Binding:
- Confirm that the suspension links are reattached correctly and are not interfering with other components.
