The Arma V3 [paid link] rear shock by EXT is a high-performance component designed to offer exceptional comfort, control, and durability for riders looking to push their bikes to the limit. However, like any advanced piece of equipment, regular maintenance and fine-tuning are required to keep the Arma V3 [paid link] functioning at its best. By performing some simple maintenance tasks and adjustments, you can significantly extend the lifespan of your rear shock and maintain peak [paid link] performance.

Tools Required

  • 8mm Allen wrench [paid link]
  • Torque wrench [paid link]
  • Soft cloth
  • Isopropyl alcohol
  • Bike stand [paid link]
  • Air shock pump
  • Grease
  • Shock oil (according to manufacturer specifications)
  • Shock pump sealant (if required)
  • Replacement seals and O-rings

Installation of the Arma V3 Rear Shock

Before installing the Arma V3 rear shock, ensure that your bike frame is compatible with the shock’s mounting dimensions. The shock features a specific eye-to-eye length and stroke length that must match your bike’s requirements.

  1. Prepare the Frame:
    • Clean the shock mounts on your bike frame with a soft cloth to remove dirt and debris.
    • Inspect the mounts for any wear or damage, ensuring that they are in good condition.
  2. Insert the Shock:
    • Place the shock onto the frame mounts, ensuring the shock’s eyelets align with the mounting holes.
    • Install the mounting bolts into the eyelets and tighten them with an 8mm Allen wrench [paid link]. Be sure to follow the recommended torque settings from the manufacturer to avoid damaging the shock or the frame.
  3. Set Sag:
    • Before you start riding, set the correct sag for your weight and riding style. Use an air shock pump to adjust the air pressure in the shock. Generally, 25-30% of the total shock travel should be used for sag.
  4. Final Check:
    • Double-check that all bolts are torqued to the correct specifications and that the shock is securely mounted. This will ensure that there are no unwanted movements or noises during riding.

Adjustment of the Arma V3 Rear Shock

The Arma V3 rear shock offers a variety of adjustments to fine-tune the suspension for different riding conditions and rider preferences. Here’s how you can adjust the shock’s features:

Rebound Damping Adjustment

The rebound damping controls the speed at which the shock returns to its original position after compression. Too fast a rebound can cause the shock to bounce back too quickly, affecting control. Conversely, too slow a rebound can cause the bike to feel sluggish.

  1. Locate the Rebound Knob:
    • The rebound adjustment knob is located at the base of the shock body.
  2. Make Adjustments:
    • Turn the knob clockwise for slower rebound (slower return).
    • Turn it counterclockwise for faster rebound (quicker return).
  3. Test and Fine-Tune:
    • After each adjustment, test ride the bike to check the rebound performance. Make incremental adjustments until the ride feels balanced and responsive.

Compression Damping Adjustment

Compression damping controls the shock’s resistance to compression, which is critical for how the shock absorbs impacts from the terrain. You can adjust the low-speed compression for smooth trails and the high-speed compression for rough, aggressive riding.

  1. Locate the Compression Knob:
    • The compression knob can usually be found near the top of the shock.
  2. Low-Speed Compression:
    • Adjust the low-speed compression for small bumps or trail chatter. Turning the knob clockwise increases resistance, and counterclockwise decreases it.
  3. High-Speed Compression:
    • High-speed compression helps with larger hits and drops. Adjust it as needed for improved control on rough trails.
  4. Test the Ride:
    • Ride on varying terrain and adjust the compression settings until you find the ideal balance for comfort and control.

Maintenance of the Arma V3 Rear Shock

Regular maintenance is crucial for keeping your Arma V3 shock in top condition. Here are some essential tasks you can perform to keep your shock working efficiently:

Cleaning the Shock

  1. Wipe Down After Rides:
    • After each ride, use a soft cloth to wipe down the shock. This prevents dirt, mud, and other debris from accumulating and causing wear.
  2. Inspect for Damage:
    • Check the shock body and mounting hardware for signs of wear, scratches, or cracks. If you notice any damage, it’s essential to address it immediately to prevent further issues.

Lubing the Shock

  1. Apply Grease to Mounting Points:
    • Apply a small amount of grease to the shock mounting points. This will help prevent squeaks and ensure smooth movement. Be careful not to over-grease, as excess grease can attract dirt.
  2. Shock Shaft Care:
    • Use a light oil or lubricant designed for shock shafts to keep the shaft sliding smoothly. This prevents dirt buildup and ensures long-term smooth operation.

Seals and O-rings

  1. Check and Replace Seals:
    • The seals and O-rings are critical components in preventing dirt and moisture from entering the shock. Regularly inspect the seals for wear or damage. If you notice any cracks or tears, replace the seals immediately.
  2. Clean and Lubricate the Seals:
    • Use isopropyl alcohol to clean the seals and O-rings, ensuring that no dirt or old lubricant remains. Apply a thin layer of lubrication to the seals to keep them functioning properly.

Air Pressure Check

Regularly check the air pressure in the shock. Over time, air can escape [paid link], causing the shock to lose its performance. Use a shock pump to add air as necessary to maintain the correct pressure for your weight and riding conditions.

Troubleshooting Common Set-Up Issues

Shock Feels Too Stiff or Too Soft

If your shock feels either too stiff or too soft, the issue may be related to the air pressure or damping settings. Follow these steps to resolve the issue:

  • Too Stiff: Decrease the air pressure slightly to allow more travel. You may also need to adjust the compression settings to soften the shock’s response.
  • Too Soft: Increase the air pressure for more support. If the sag is too deep, it can cause the shock to feel overly soft. Make sure you have the correct sag setting based on your weight.

Unwanted Noises or Creaking

Creaking sounds often result from loose bolts, inadequate lubrication, or worn-out seals.

  • Check Bolts: Ensure that all mounting bolts are tightened to the correct torque.
  • Lubricate Mounts: Apply grease to the shock mounts and ensure that the shock shaft is properly lubricated.
  • Inspect Seals: Check the seals for wear and replace them if needed.

Customization and Optimization for Better Performance

To get the most out of your Arma V3 rear shock, consider adjusting its settings for your specific riding style and terrain.

  • Set Up for Climbing: If you primarily ride uphill, adjust the low-speed compression to provide extra resistance and minimize bobbing.
  • Set Up for Descending: For downhill or aggressive riding, increase the high-speed compression damping to improve control during big impacts and fast descents.

Experiment with the various settings to find the balance that works best for your style of riding. Regularly maintaining and optimizing the shock based on your riding conditions will ensure it continues to perform at its best for years to come.

Conclusion

Maintaining and optimizing the Arma V3 rear shock doesn’t have to be difficult. By following these simple DIY hacks for installation, adjustment, maintenance, and troubleshooting, you can keep your shock running smoothly and extend its lifespan. Regular care will not only enhance your riding experience but also help you get the most out of your investment in this high-performance rear shock.
