1. Product Overview
This manual provides instructions for the HAIBOXING All Metal Shock Absorber Set, model 16HOP1 (M1882). This set includes four all-metal dampers designed to enhance the suspension performance of compatible 1/16 scale RC cars, including models HBX16889, 16890a, 16889A, and 16889PRO. These shocks are intended as an upgrade to improve handling and stability.

2. Compatibility
The HAIBOXING 16HOP1 shock absorber set is designed for use with 1/16 scale RC cars. Specifically, it is compatible with the following HAIBOXING models:
- HBX16889
- HBX16890a
- HBX16889A
- HBX16889PRO
These shocks may also be compatible with other 1/16 scale RC cars that utilize similar shock dimensions and mounting points. Always verify dimensions before installation.

3. Installation Guide
Before beginning installation, ensure your RC car is powered off and the battery is disconnected. It is recommended to work on a clean, flat surface to prevent loss of small parts.
3.1 Tools Required
- Small Phillips head screwdriver
- Hex wrench (if applicable for existing shock mounts)
- Pliers (optional, for stubborn fasteners)
3.2 Step-by-Step Installation
- Remove Existing Shocks: Carefully unscrew the mounting screws that secure the top and bottom of each existing shock absorber to the chassis and suspension arms of your RC car. Keep these screws organized, as some may be reused.
- Prepare New Shocks: The HAIBOXING 16HOP1 shocks come pre-assembled. Inspect each shock for any visible damage or loose parts. Ensure the included mounting screws are ready for use.
- Mount New Shocks:
- Align the top mounting eyelet of a new shock with the corresponding mounting point on the RC car's chassis. Secure it with a screw. Do not overtighten.
- Align the bottom mounting eyelet of the same shock with the corresponding mounting point on the suspension arm. Secure it with a screw. Do not overtighten.
- Repeat this process for all four shock absorbers.
- Check Suspension Travel: Once all shocks are installed, gently compress and extend each suspension arm to ensure smooth movement and full travel without binding. The shocks should compress and rebound freely.
- Final Inspection: Verify that all screws are securely fastened and that the shocks are properly seated.

4. Operation and Performance
After successful installation, the HAIBOXING 16HOP1 all-metal shock absorbers will provide improved damping and suspension response compared to standard friction shocks. These oil-filled shocks are designed to absorb impacts more effectively, leading to enhanced stability and control during driving, especially over rough terrain or during jumps.
- Improved Handling: Expect better traction and reduced chassis roll during turns.
- Smoother Landings: The oil-filled design helps dissipate energy from impacts, resulting in softer landings after jumps.
- Increased Durability: The all-metal construction offers greater resistance to wear and tear compared to plastic components.
The performance of the shocks can be further tuned by adjusting the spring preload (if applicable) or by changing the internal shock oil viscosity (advanced users).
5. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your shock absorbers.
- Cleaning: After each use, especially in dusty or muddy conditions, clean the exterior of the shocks with a soft brush or cloth to remove dirt and debris. Avoid using harsh chemicals that could damage seals.
- Inspection: Periodically check for signs of oil leakage around the shock shafts and caps. Inspect the springs for any deformation or damage. Ensure all mounting screws remain tight.
- Shock Oil Replacement (Advanced): Over time, shock oil can degrade. For advanced users, replacing the shock oil can restore damping performance. This typically involves disassembling the shock, draining old oil, refilling with new oil of appropriate viscosity, and bleeding air. Refer to specialized RC maintenance guides for detailed steps on shock rebuilding.
- Shaft Condition: Keep the shock shafts clean and free of scratches. Scratches can damage the O-rings and lead to leaks.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Poor damping performance / Bouncy ride | Low shock oil level, incorrect oil viscosity, damaged O-rings, bent shock shaft. | Inspect for leaks. If leaking, replace O-rings and refill with appropriate shock oil. Consider heavier weight shock oil for stiffer damping. Check shock shafts for bends. |
| Oil leakage from shocks | Damaged O-rings, loose shock caps, scratched shock shaft. | Tighten shock caps. Replace O-rings. If shaft is scratched, it may need replacement. |
| Shocks not fully extending or binding | Bent shock shaft, debris inside shock body, incorrect mounting. | Disassemble and clean shocks. Check for bent shafts. Re-check mounting to ensure no binding. |
| Excessive body roll | Springs too soft, insufficient damping. | Consider stiffer springs or heavier weight shock oil. |
