What's in the Box
Your package should contain the following items:
- 2 x Oil-Filled Shock Absorbers (70mm red)
- Mounting Screws (quantity as needed for installation)
Please inspect all components upon receipt. If any items are missing or damaged, contact customer support immediately.
Setup and Installation
Follow these steps to properly install your RCJUMPANT Oil-Filled RC Shocks:
- Remove Old Shocks: Carefully remove the existing shock absorbers from your RC vehicle. Refer to your RC vehicle's manual for specific instructions on shock removal.
- Inspect New Shocks: Before installation, ensure the new RCJUMPANT shocks are in good condition and that the oil is properly filled. The shocks are pre-filled, but a visual check is recommended.
- Mount New Shocks: Attach the new shocks to your RC vehicle using the provided mounting screws. Ensure they are securely fastened but do not overtighten. The top and bottom mounting points should align correctly.
- Adjust Pre-Load: The threaded shock bodies allow for pre-load adjustment. Rotate the spring collar to compress or decompress the spring. Increasing pre-load (compressing the spring) will raise the ride height and stiffen the suspension. Decreasing pre-load will lower the ride height and soften the suspension. Adjust all shocks evenly for balanced performance.
- Test Suspension: After installation and initial adjustment, gently compress the suspension of your RC vehicle to ensure smooth movement and proper rebound. Make further adjustments as needed.

Operating Guidelines
Once installed, your RCJUMPANT Oil-Filled RC Shocks will provide improved handling and stability. Consider the following for optimal performance:
- Driving Conditions: Adjust your shock settings (pre-load) based on the terrain. Softer settings are generally better for rough, uneven surfaces, while stiffer settings are preferred for smooth tracks and high-speed driving.
- Observation: Pay attention to how your RC vehicle handles after adjustments. Observe for excessive bouncing, bottoming out, or lack of traction, and fine-tune the shocks accordingly.
- Break-in Period: New shocks may require a short break-in period. Operate your RC vehicle gently for the first few runs to allow the seals and oil to settle.
Maintenance
Regular maintenance will extend the life and performance of your RCJUMPANT Oil-Filled RC Shocks:
- Cleaning: After each use, especially in dirty or dusty conditions, clean the exterior of the shocks with a soft brush and a damp cloth. Avoid using harsh chemicals that could damage the seals or finish.
- Inspect for Leaks: Periodically check for any signs of oil leakage around the seals. While designed to be leak-proof, extreme conditions or damage can compromise seals. Address any leaks promptly.
- Shaft Inspection: Ensure the shock shafts are clean and free of nicks or scratches, which can damage seals and cause leaks.
- Oil Replacement: Over time, shock oil can degrade. For competitive use or after extensive operation, consider replacing the shock oil. This typically involves disassembling the shock, draining the old oil, and refilling with fresh 100CPS shock oil. Refer to online resources or professional guides for detailed shock rebuilding procedures.
- Spring Tension: Regularly check and adjust spring pre-load to maintain desired ride height and suspension characteristics.
Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Excessive Bouncing / Poor Damping | Low shock oil level or degraded oil. | Check oil level and condition. Refill or replace shock oil. |
| Shocks Bottoming Out Easily | Insufficient spring pre-load or too soft springs. | Increase spring pre-load by rotating the collar. Consider stiffer springs if necessary. |
| Oil Leakage | Damaged O-rings or seals. | Disassemble the shock and replace damaged O-rings or seals. Ensure proper assembly. |
| Uneven Ride Height | Uneven pre-load settings across shocks. | Adjust pre-load evenly on all shocks. Measure ride height for consistency. |
