- Pistons: Different piston designs for varied damping curves.
- Valves: Assorted valves for fine-tuning shock performance.
Refer to the specific instructions provided with your QA1 26/27 Series Monotube Shocks for detailed identification and application of each component.
3. Setup and Installation
The QA1 TK08 Monotube Tuning Kit is intended for use by experienced individuals or professional technicians. Proper installation and valving require specialized tools and knowledge of shock absorber mechanics. Incorrect assembly or valving can lead to poor vehicle handling, component damage, or safety hazards.
General Installation Steps (Consult your shock manual for specifics):
- Preparation: Ensure the vehicle is safely supported and the shocks are removed. Clean the work area and all shock components thoroughly.
- Disassembly: Carefully disassemble the QA1 26/27 Series Monotube Shocks according to the manufacturer's instructions. This typically involves depressurizing the shock and removing the shaft assembly.
- Valving Selection: Based on desired performance characteristics (e.g., firmer compression, softer rebound), select the appropriate disc valves, pistons, and other components from the TK08 kit. Refer to QA1's valving guides or consult a suspension specialist for recommendations.
- Assembly: Install the selected valving components onto the shock shaft assembly. Ensure all O-rings are properly seated and lubricated with appropriate shock fluid.
- Reassembly: Reassemble the shock absorber, ensuring all components are correctly aligned and torqued to specifications. Recharge the shock with nitrogen to the recommended pressure.
- Installation on Vehicle: Reinstall the shocks onto the vehicle, ensuring all mounting hardware is secure.
It is highly recommended to consult the official QA1 shock absorber manual for detailed, model-specific disassembly, assembly, and valving procedures.
4. Operating and Tuning
The TK08 kit provides the components necessary to modify the internal damping characteristics of your QA1 Monotube Shocks. "Operating" in this context refers to the process of selecting and installing the correct valving to achieve desired suspension performance.
Tuning Principles:
- Compression Damping: Controls the rate at which the shock compresses. Stiffer compression valving resists suspension compression more, often used for handling heavy loads or aggressive driving.
- Rebound Damping: Controls the rate at which the shock extends after compression. Stiffer rebound valving slows down the extension, preventing excessive body roll or wheel lift.
- Valving Stacks: The combination and order of disc valves create a "valving stack" that dictates the shock's damping curve. Experimentation and data logging are often required for optimal tuning.
Begin with a baseline valving setup recommended by QA1 or a suspension expert. Make small, incremental changes and test the vehicle's behavior after each adjustment. Keep detailed records of valving configurations and their effects on performance.
5. Maintenance and Storage
Proper maintenance and storage of the TK08 kit components will ensure their longevity and readiness for future use.
Maintenance:
- Cleaning: After use, clean any components that came into contact with shock fluid using a suitable solvent or cleaner. Ensure they are completely dry before storage.
- Inspection: Periodically inspect O-rings and other soft components for signs of wear, cracking, or degradation. Replace as necessary.
- Lubrication: When installing O-rings, always lubricate them with clean shock fluid or a compatible lubricant to prevent damage during assembly.
Storage:
- Organized Storage: Always return unused components to their designated compartments within the provided storage case. This prevents loss and damage.
- Environment: Store the kit in a cool, dry place away from direct sunlight, extreme temperatures, and corrosive chemicals.
- Security: Ensure the case latches are securely fastened to prevent accidental opening and spilling of components.
6. Troubleshooting
This section addresses common issues that may arise during or after the valving process. Note that this kit provides components for tuning, and issues often stem from incorrect valving choices or improper shock assembly.
| Problem | Possible Cause | Solution |
|---|---|---|
| Shock feels too stiff/harsh | Excessive compression damping; too stiff valving stack. | Reduce compression valving stiffness. Consult valving charts for softer options. |
| Shock feels too soft/bouncy | Insufficient compression or rebound damping; too soft valving stack. | Increase compression and/or rebound valving stiffness. Ensure proper nitrogen pressure. |
| Shock leaking fluid | Damaged or improperly seated O-rings; incorrect assembly. | Disassemble, inspect all seals and O-rings. Replace damaged ones and reassemble carefully, ensuring proper lubrication. |
| Inconsistent damping | Air in shock fluid; damaged internal components; incorrect fluid level. | Professional service recommended. Ensure proper bleeding during assembly and correct fluid volume. |
For complex issues or if you are unsure about any procedure, it is strongly advised to contact QA1 technical support or a certified suspension specialist.
