Basic Installation and Setup of the Van RC Performance Rear Shock

Installing the Fox Van RC Performance rear shock requires attention to detail to ensure it’s done correctly. Whether replacing an old shock or upgrading to this model, follow these steps for a smooth installation.

Step 1: Removing the Old Shock

  • Use a 5mm Allen wrench [paid link] to remove the bolts securing the old shock to your frame. Ensure that you keep track of any washers or spacers used.
  • Gently remove the shock from the frame, being cautious not to damage any other components in the process.

Step 2: Installing the New Shock

  • Position the Fox Van RC Performance rear shock into place on the frame.
  • Align the shock mounts with the holes on the frame and insert the bolts. Use a torque wrench [paid link] to tighten the bolts according to the manufacturer’s recommended torque specifications.
  • Make sure the shock is securely fastened, with no play or movement in the shock mount.

Step 3: Setting the Air Pressure

  • Attach a shock pump to the air valve on the rear shock.
  • Adjust the air pressure according to your body weight and riding style. For a general starting point, refer to the pressure guidelines provided by Fox.
  • Check the air pressure regularly as it can fluctuate over time due to temperature changes and riding conditions.

Maintenance Tips for Prolonging the Life of Your Van RC Performance Rear Shock

Regular maintenance ensures your rear shock continues to perform at its best. Performing simple maintenance tasks can prevent premature wear and tear, saving you money in the long run.

Regular Cleaning and Lubing

  • Clean your shock after every ride to prevent dirt and debris from accumulating in the seals. Use a rag soaked in isopropyl alcohol to wipe down the shock body and the air sleeve.
  • Apply a light layer of suspension grease to the shock mount areas to minimize friction and ensure smooth movement.

Checking for Leaks

  • Examine the seals and air sleeve of the shock for any visible leaks. If you notice oil residue around the seals, it may be time to replace them. Leaking air or oil can cause the shock to lose performance and could eventually damage the internals.

Air Pressure Adjustments

  • Check and adjust the air pressure every few rides to maintain the correct setup. If you notice any sag or harsh bottoming out, it’s time to either reduce or increase the pressure accordingly.
  • Always use a reliable shock pump to make precise adjustments.

Rebuilding the Shock (If Necessary)

  • If the shock is not performing as expected or you notice significant wear on the seals, consider a full rebuild. This includes replacing the seals, oil, and possibly the air spring components.
  • Always use genuine Fox components for the rebuild to ensure the shock operates as intended.

Troubleshooting Common Van RC Performance Rear Shock Issues

Despite its high-quality build, your Fox Van RC Performance rear shock may face some common issues over time. Here’s how to troubleshoot and address them effectively.

Lack of Rebound or Compression Dampening

  • Cause: The internal oil may have degraded, or the rebound/compression adjusters might be set incorrectly.
  • Solution: Inspect the shock’s internals for oil leakage or contamination. Refill the shock with fresh oil if necessary. If the adjustment knobs are not responding, ensure they are turned fully to their respective settings.

Bottoming Out or Harsh Ride

  • Cause: Insufficient air pressure, poor shock tuning, or damaged components.
  • Solution: Check and adjust the air pressure according to your riding conditions and body weight. If the shock is still bottoming out, consider tuning the compression settings or rebuilding the shock to replace any damaged components.

Noisy Shock

  • Cause: Dirt buildup, lack of lubrication, or dry seals.
  • Solution: Clean the shock thoroughly and lubricate the mounting hardware. Ensure that the shock seals are in good condition and replace them if necessary.

Customization and Optimization of Your Van RC Performance Rear Shock

Optimizing the Fox Van RC Performance rear shock to suit your riding style can make a world of difference. Here are some tips for customization:

Tuning the Rebound and Compression Settings

  • The Fox Van RC rear shock features both rebound and compression adjustment. Begin by setting the rebound to a neutral position (typically 12-15 clicks out from fully closed).
  • Adjust the compression to suit your riding terrain. For smoother trails, a more open setting is ideal, while rougher terrain might benefit from a firmer compression.

Fine-Tuning Air Pressure

  • The Fox Van RC Performance shock uses air spring technology, which can be customized for different rider weights and riding styles. Increase the air pressure for a firmer ride or decrease it for more comfort and smoother performance.

Spring Rate Selection

  • If you’re looking for a more advanced customization, you can swap out the air spring or adjust the shock’s coil spring to match your preferred ride quality. This may involve experimenting with different spring rates based on your riding conditions and body weight.

Compatibility with Other Drivetrain Components

Ensuring that your Fox Van RC Performance rear shock works seamlessly with your other drivetrain components is vital for optimal performance. Here’s how it fits within your bike’s overall setup:

  • Frame Compatibility: Ensure your bike frame is compatible with the dimensions and mounting system of the Fox Van RC rear shock. The shock is typically designed for a wide range of mountain bike frames, but it’s important to double-check the specific fit for your bike.
  • Linkage and Suspension Design: Your bike’s linkage system will also affect how the rear shock performs. Some linkage designs are better suited for certain types of shock damping, so consider how your bike’s geometry interacts with the shock’s settings.
  • Other Suspension Components: If you are running a front suspension fork, it is recommended to match the travel of the rear shock to the fork to maintain consistent suspension performance across your bike. The balance between front and rear suspension will directly influence handling and stability.

Conclusion

The Fox Van RC Performance rear shock is a robust and reliable component that can significantly enhance your ride when maintained properly. By following the installation and maintenance tips provided, addressing common issues, and customizing the shock to suit your needs, you can maximize its lifespan and performance. Whether you are a recreational rider or a seasoned racer, keeping your rear shock in top shape is essential for getting the most out of your bike and ensuring a smooth, enjoyable ride.
