2. Safety Information
Always prioritize safety when working on vehicle suspension systems. Improper installation or handling can lead to serious injury or vehicle damage.
- Professional Installation Recommended: Installation of automotive suspension components should ideally be performed by a qualified mechanic with experience in vehicle suspension systems.
- Use Proper Tools: Ensure you have the correct tools for the job, including a reliable vehicle lift or jack stands, torque wrench, and appropriate sockets/wrenches.
- Wear Personal Protective Equipment (PPE): Always wear safety glasses, gloves, and appropriate work attire to protect against potential hazards.
- Secure Vehicle: Before beginning any work, ensure the vehicle is securely supported on a level surface using jack stands. Never rely solely on a jack.
- Consult Vehicle Service Manual: Refer to your specific vehicle's service manual for detailed instructions on shock absorber removal and installation procedures, including torque specifications.
- Spring Compression: Be aware that coil springs can store significant energy. If spring compression is required, use a certified spring compressor tool and exercise extreme caution.
- Inspect Components: Before installation, inspect all components for damage or defects. Do not install damaged parts.

4. Installation Guide
This section provides a general guide for installing the REKUDO 68-72 A-Body Front Shock Adjustable. Always consult your vehicle's specific service manual for detailed, model-specific instructions and torque specifications.
4.1. Preparation
- Park the vehicle on a firm, level surface.
- Engage the parking brake.
- Loosen the lug nuts on the front wheels.
- Safely lift the front of the vehicle using a hydraulic jack and support it securely with jack stands placed under the frame rails. Ensure the vehicle is stable before proceeding.
- Remove the front wheels.
4.2. Removal of Old Shock Absorber
- Locate the upper and lower mounting points of the existing front shock absorber.
- Carefully remove the nuts and bolts securing the shock absorber to its mounting points. You may need to hold the bolt head while loosening the nut.
- Once both mounting points are disconnected, carefully remove the old shock absorber from the vehicle.
4.3. Installation of New Shock Absorber
- Before installing the new REKUDO shock, ensure it is fully extended or compressed as needed for proper fitment.
- Install the new shock absorber by aligning its upper mounting point with the vehicle's upper shock mount. Insert the bolt and loosely secure with the nut.
- Align the lower mounting point of the shock with the vehicle's lower shock mount. Insert the bolt and loosely secure with the nut.
- Once both mounting points are aligned and loosely secured, tighten the upper and lower mounting bolts to the torque specifications provided in your vehicle's service manual. Do not overtighten.

4.4. Post-Installation
- Reinstall the front wheels and tighten the lug nuts hand-tight.
- Carefully lower the vehicle to the ground.
- Torque the lug nuts to the vehicle manufacturer's specifications using a torque wrench.
- Perform a test drive in a safe area to ensure proper function and no unusual noises.
5. Operation and Adjustment
The REKUDO 68-72 A-Body Front Shock is designed to be adjustable, allowing for fine-tuning of your vehicle's ride characteristics. While specific adjustment mechanisms can vary, adjustable shocks typically feature a knob or a series of detents that can be turned to alter the damping force (rebound and/or compression).
- Understanding Adjustments: Adjusting the shock typically changes its stiffness. A firmer setting provides more control and reduced body roll, while a softer setting offers a more comfortable ride.
- How to Adjust: Locate the adjustment mechanism, usually at the top or bottom of the shock body. Follow the manufacturer's specific instructions for the number of clicks or turns for desired stiffness.
- Symmetry: Always adjust both front shocks to the same setting to maintain balanced handling and prevent uneven wear.
- Test and Refine: After making adjustments, test drive the vehicle in a safe environment to evaluate the changes. Make small, incremental adjustments until the desired ride quality is achieved.

6. Maintenance
Proper maintenance can extend the life and performance of your REKUDO shock absorbers.
- Regular Inspection: Periodically inspect the shocks for signs of leakage, damage, or wear. Check the mounting bushings for cracks or deterioration.
- Cleanliness: Keep the shock bodies clean, especially around the shaft and seals, to prevent dirt and debris from causing premature wear.
- Check Mounting Hardware: Ensure all mounting bolts and nuts remain tight and secure. Re-torque if necessary according to vehicle specifications.
- Avoid Harsh Chemicals: Do not use harsh solvents or abrasive cleaners on the shock body or shaft, as they may damage seals or finishes.

7. Troubleshooting
If you experience issues with your REKUDO shock absorbers, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Excessive Bouncing / Poor Ride Quality | Worn out shock, incorrect adjustment, or damaged internal components. | Inspect for leaks. Adjust damping settings. If severe, replacement may be necessary. |
| Clunking or Rattling Noise | Loose mounting hardware, worn bushings, or internal shock damage. | Check and re-torque mounting bolts. Inspect bushings for wear and replace if needed. |
| Oil Leakage from Shock Body | Damaged seal or internal component failure. | This indicates a failed shock absorber. Replacement is required. |
| Uneven Ride Height | Incorrect spring installation (if applicable), or a failed shock/spring on one side. | Inspect springs and shocks on both sides. Ensure adjustments are symmetrical. |
If troubleshooting steps do not resolve the issue, it is recommended to consult a professional automotive technician.
