Tools Required

Before starting any maintenance on your Van RC Performance Rear Shock, make sure you have the following tools:

  • 5mm Allen wrench [paid link]
  • 8mm wrench
  • Torque wrench [paid link]
  • Shock pump
  • 15mm socket wrench (for removing the shock)
  • Clean, lint-free cloth
  • Suspension fluid
  • Grease (specifically designed for suspension parts)
  • Teflon tape
  • Replacement seals (if necessary)

Installation of the Van RC Performance Rear Shock

Installing the Van RC Performance Rear Shock is a straightforward process that requires precision and the correct torque values. Follow these steps to ensure a proper installation:

  1. Prepare the Frame and Rear Shock Mounting Points:
    • Clean the shock mounting points on both the frame and the shock itself to remove any dirt, grease, or old lubricant.
    • Apply a small amount of grease to the mounting hardware to ensure smooth installation and prevent creaking.
  2. Align the Rear Shock with the Mounting Points:
    • Slide the shock into the rear suspension frame. Align the mounting holes on the shock with the mounting points on the bike’s frame.
  3. Insert the Mounting Bolts:
    • Insert the bolts into the mounting points and tighten them slightly by hand to hold the shock in place.
  4. Torque the Bolts to Specification:
    • Using a torque wrench [paid link], tighten the bolts to the manufacturer’s recommended torque value (usually around 150-200 in-lbs, depending on the specific model).
  5. Check the Alignment and Movement:
    • Before fully tightening everything, check the shock’s alignment to ensure it moves freely within the frame’s suspension. There should be no resistance or binding.
  6. Final Tightening:
    • After confirming the alignment, torque the bolts to the final specifications. Double-check for any play or unwanted movement.

Adjustment of the Van RC Performance Rear Shock

Proper adjustments to your Van RC Performance Rear Shock can significantly affect the comfort and efficiency of your ride. This shock features compression and rebound adjustments that should be tuned based on your weight, riding style, and terrain. Here’s how to adjust both:

Compression Adjustment

  1. Locate the Compression Dial:
    • The compression dial is usually located near the top of the shock, typically on the right-hand side. This dial controls how the shock responds to bumps and impacts.
  2. Adjust for Your Weight and Riding Style:
    • Start by turning the compression dial to a middle setting. For a firmer ride with less suspension movement, turn the dial clockwise to increase compression damping.
    • For more comfort and a smoother ride, turn the dial counterclockwise to decrease compression damping. If you are riding on rough terrain, you may want to decrease damping for better shock absorption.
  3. Fine-Tune the Setting:
    • Once you’ve selected your starting point, ride the bike to see how the shock behaves. Make small adjustments to the compression to achieve the desired level of comfort and control. A well-tuned compression setting will give you a responsive feel without bottoming out.

Rebound Adjustment

  1. Locate the Rebound Dial:
    • The rebound dial is typically found at the bottom of the shock. This controls the rate at which the shock returns to its original position after compressing.
  2. Adjust for Terrain and Rider Preferences:
    • Turning the dial clockwise slows down the rebound, which can be useful for rougher terrain or for riders who prefer more control.
    • Turning it counterclockwise speeds up the rebound, making the shock return faster. This is typically better for smoother trails where quick response is needed.
  3. Test the Settings:
    • After adjusting the rebound, ride the bike and observe how the shock behaves when it returns. If the shock rebounds too quickly, it may cause the bike to become bouncy and less stable. If it rebounds too slowly, the shock may feel sluggish and unresponsive.

Regular Maintenance of the Van RC Performance Rear Shock

Maintaining the Van RC Performance Rear Shock involves regular cleaning, lubrication, and servicing. The frequency of these tasks depends on your riding conditions, but as a general guideline, perform the following steps every few months or after heavy use.

Cleaning the Shock

  1. Remove Excess Dirt and Debris:
    • Use a clean, lint-free cloth to wipe down the shock after each ride. Remove any dirt, mud, or grit that may have accumulated on the shock’s body and seals.
  2. Check the Seals:
    • Inspect the seals for any wear, tears, or leaks. If you notice damage, it’s time to replace them to prevent dirt from entering the shock and affecting its performance.

Lubrication

  1. Apply Suspension Fluid:
    • Using suspension-specific oil, lightly lubricate the shock’s moving parts. Apply fluid to the stanchions and any areas where friction occurs, ensuring that the shock moves freely without any grinding or sticking.
  2. Grease the Mounting Points:
    • Before re-installing the shock, apply a small amount of grease to the mounting hardware and bolts to ensure smooth movement and prevent corrosion.

Seal Maintenance and Replacement

  1. Inspect Seals Regularly:
    • Seals should be inspected at least once a year or more often if you’re riding in harsh conditions. Look for any signs of oil leakage or wear.
  2. Replacing Seals:
    • If the seals are compromised, it’s crucial to replace them to prevent contamination of the shock’s internals. Replace seals with OEM parts to ensure proper fitment and performance.

Troubleshooting Common Issues with the Van RC Performance Rear Shock

While the Van RC Performance Rear Shock is a durable and high-performance component, like any piece of gear, it may encounter issues over time. Here are a few common problems and how to address them:

Shock Not Rebounding Properly

  • Possible Cause:
    • The rebound adjustment is set too slow, or the shock fluid has degraded.
  • Solution:
    • Adjust the rebound dial to a faster setting. If that doesn’t resolve the issue, it may be time for a fluid change or internal servicing.

Shock Bottoming Out

  • Possible Cause:
    • The compression adjustment is set too soft for your weight or riding style.
  • Solution:
    • Increase the compression damping by turning the dial clockwise. This will reduce the shock’s travel and prevent it from bottoming out under heavy impacts.

Noisy Shock

  • Possible Cause:
    • Dirt or debris inside the shock, or inadequate lubrication.
  • Solution:
    • Clean and lubricate the shock, ensuring that all moving parts are free of contaminants and properly oiled.

Customization and Optimization for Better Performance

To optimize your Van RC Performance Rear Shock for specific riding conditions or personal preferences, consider the following adjustments:

Air Pressure and Volume Adjustments

  • Adjusting the air pressure in your shock’s air chamber is an effective way to fine-tune the shock for your weight and riding style. Lighter riders may want to reduce the pressure for better comfort, while heavier riders should increase it for better support and responsiveness.
  • Volume spacers can also be added or removed to modify the shock’s progression. More spacers increase the firmness toward the end of the stroke, which can be beneficial for riders looking for a more controlled ride on steep descents.

Tuning for Terrain

  • For aggressive downhill riding, you might want to use a softer setting for compression and rebound, allowing the shock to absorb the harsher impacts. Conversely, for cross-country or climbing, you may prefer a firmer compression and faster rebound to maximize efficiency.

Compatibility with Other Drivetrain Components

The Van RC Performance Rear Shock is compatible with most modern mountain bikes with an appropriate rear shock mount. However, always verify the shock size, stroke length, and mounting hardware compatibility with your bike frame before purchasing. This will ensure that the shock works optimally with your bike’s other drivetrain components.

Conclusion

Proper installation, adjustment, maintenance, and troubleshooting of the Van RC Performance Rear Shock will significantly enhance your riding experience. By following these steps and making small adjustments based on your specific needs, you can ensure that your shock provides the best performance possible. Whether you’re tackling challenging trails or enjoying a leisurely ride, keeping your rear shock in top condition is essential for a smooth and efficient bike setup.
