4. Setup and Installation
4.1 Tools Required
- Small Phillips Head Screwdriver (for removing existing shocks)
- Hex Key (included, for mounting new shocks)
- Small Pliers or Tweezers (optional, for spring changes)
4.2 Installation Steps
Follow these steps to install your new INJORA shocks:
- Prepare Your RC Crawler: Ensure your RC crawler is powered off and placed on a stable surface.
- Remove Existing Shocks: Carefully unbolt and remove the stock shocks from your RC crawler. Keep track of any small parts.
- Select Spring Rate: The INJORA shocks come with three sets of springs: Soft (Black), Medium (Silver), and Hard (Gold). Choose the spring rate that best suits your driving style and terrain. For initial setup, the pre-installed springs (typically medium) are a good starting point.
- Install New Shocks: Align the mounting holes of the INJORA shocks with the mounting points on your RC crawler's chassis and axle. Use the provided screws and hex key to securely fasten the shocks. Do not overtighten.
- Check Clearance and Articulation: Once all shocks are installed, gently compress and extend the suspension to ensure there is no binding and that the full range of motion is achieved. Verify that no components interfere with the shock's movement.

5. Operating Guidelines
The INJORA 32mm shocks are designed to improve the crawling performance of your Axial SCX24. The internal spring design provides consistent damping. Experiment with different spring rates to fine-tune your vehicle's suspension for various terrains and weight distributions.
5.1 Spring Rate Adjustment
Changing the springs allows you to adjust the stiffness of your suspension:
- Soft Springs (Black): Provide maximum articulation and flex, ideal for technical crawling over uneven surfaces where maximum grip is required.
- Medium Springs (Silver): Offer a balanced performance, suitable for general trail driving and moderate crawling.
- Hard Springs (Gold): Reduce body roll and provide a firmer ride, beneficial for higher speed sections or when carrying additional weight.
To change springs, carefully unscrew the top cap of the shock body, remove the existing spring, and replace it with your desired spring. Ensure the cap is securely re-tightened.
6. Maintenance
Regular maintenance will help preserve the performance and lifespan of your INJORA shocks:
- Cleaning: After each use, especially in dirty or wet conditions, clean the shocks with a soft brush and a damp cloth to remove dirt and debris.
- Inspection: Periodically inspect the shock shafts for bends or scratches, and check the mounting points for any looseness or damage.
- Lubrication: While these are internal spring air dampers, a small amount of silicone shock oil can be applied to the shock shaft if you notice any friction or sticking during compression. Avoid petroleum-based lubricants as they can damage plastic components.
- Spring Check: Ensure springs are not bent or fatigued. Replace if necessary.
7. Troubleshooting
Here are solutions to common issues you might encounter:
- Shocks Feel Too Stiff:
- Ensure you have the softest springs (Black) installed.
- Check for any binding in the suspension linkage or chassis components.
- Apply a small amount of silicone shock oil to the shock shaft for smoother operation.
- Shocks Feel Too Soft / Excessive Body Roll:
- Install harder springs (Silver or Gold) to increase damping and reduce body roll.
- Verify that all mounting screws are tight.
- Shock Binding or Sticking:
- Inspect the shock shaft for any debris or damage. Clean thoroughly.
- Ensure the shock is mounted straight and not at an extreme angle causing friction.
- Lubricate the shaft with silicone shock oil.
