1. Product Overview
The INJORA High Clearance Links Set (Model 4M-73) is an upgrade component designed for 1/18 scale RC crawlers, specifically the TRX4M High Trail K10 and F150 models. This set replaces the factory plastic links with durable CNC anodized aluminum links, featuring bent designs for increased ground clearance during climbing. The inclusion of brass link balls further enhances performance and durability.

2. Key Features
- CNC Anodized Aluminum Construction: Provides superior durability and long-lasting performance compared to stock plastic links.
- High Clearance Design: Bent links are engineered to offer increased ground clearance, improving climbing capabilities and obstacle navigation.
- Lightweight: Each link set weighs approximately 19g (0.67oz), minimizing added weight to the vehicle.
- Enhanced Stability and Precision: Upgrading to these links contributes to improved vehicle stability, precision, and overall crawling performance.
- Brass Link Balls: Utilizes brass link balls for a snug yet flexible fit, ensuring smooth articulation.

3. Compatibility
This High Clearance Links Set is precisely designed for the following 1/18 scale RC crawler models:
- TRX4M High Trail K10
- TRX4M F150
Important Note: This set is not compatible with TRX4M Defender and Bronco models.
4. Package Contents
The package typically includes a complete set of high clearance aluminum links and corresponding brass link balls required for a full vehicle upgrade. The exact number of links may vary based on the specific vehicle configuration (e.g., front and rear upper/lower links).

5. Setup and Installation
Installation of the INJORA High Clearance Links Set requires basic RC tools, such as small hex wrenches and possibly needle-nose pliers. It is recommended to work on a clean, well-lit surface.
- Preparation: Ensure your RC crawler is powered off and the battery is disconnected. Place the vehicle on a stable surface.
- Identify Links: Carefully identify the stock plastic links that will be replaced. Note their position and orientation (upper/lower, front/rear). The new links come in various lengths and some are bent for clearance. Match the new links to the old ones based on length and intended position.
- Remove Stock Links: Using appropriate tools, carefully remove one stock link at a time. This helps maintain the chassis geometry during the process.
- Install New Links: Attach the new INJORA aluminum links, ensuring the brass link balls are properly seated. For bent links, ensure the bend is oriented to provide maximum clearance (typically bending upwards or away from the chassis).
- Secure Fasteners: Tighten all screws securely, but do not overtighten, as this can strip threads or restrict movement.
- Repeat for All Links: Continue this process for all remaining links, working systematically.
- Final Check: Once all links are installed, gently articulate the suspension to ensure all components move freely without binding. Check for any loose connections.

6. Operating Considerations
After installing the high clearance links, you should observe improved performance in challenging terrains. The bent design allows the chassis to clear obstacles more effectively, reducing hang-ups and increasing the vehicle's capability on rocks and uneven surfaces. The enhanced rigidity of aluminum links over plastic also contributes to more precise handling and stability.
7. Maintenance
To ensure the longevity and optimal performance of your INJORA High Clearance Links, regular maintenance is recommended:
- Cleaning: After each use, especially in dirty or wet conditions, clean the links to remove dirt, mud, and debris. A soft brush and mild soap with water can be used, followed by thorough drying.
- Inspection: Periodically inspect the links for any signs of wear, bending, or damage. Check the brass link balls for smooth movement and ensure they are not seized or excessively worn.
- Fastener Check: Verify that all screws attaching the links are tight. Vibrations during operation can sometimes loosen fasteners.
- Lubrication: While not typically required for the links themselves, ensure any associated pivot points or suspension components are adequately lubricated according to your RC vehicle's manual.
8. Troubleshooting
- Links Bending: While made of durable aluminum, extreme impacts or falls can cause links to bend. If a link is bent, it should be replaced to maintain proper suspension geometry and performance. Avoid excessive force during operation.
- Restricted Suspension Movement: If the suspension feels stiff or binds after installation, re-check all fasteners to ensure they are not overtightened. Also, verify that the brass link balls are properly seated and moving freely within their sockets.
- Incorrect Clearance: Ensure that the bent links are installed with the correct orientation to maximize ground clearance. Incorrect installation may negate the high-clearance benefit.
