  • Torque wrench [paid link]
  • 8mm and 10mm Allen wrenches [paid link]
  • 5mm and 6mm Allen wrenches [paid link]
  • Suspension fluid (Fox Float Fluid)
  • Clean rags
  • Grease (suspension-safe)
  • Needle-nose pliers
  • Seal kit (Fox service kit for DHX2)
  • Stanchion oil (Fox Float Fluid)

Installation of the Fox DHX2 Performance Elite Rear Shock

Installing the Fox DHX2 Performance Elite Rear Shock correctly is crucial for maximizing its performance and durability. Follow these steps to ensure a secure and functional setup:

  1. Prepare the Frame and Shock:
    • Clean the shock mounting points on your bike frame and the shock itself to remove any dirt or debris. This prevents contamination and ensures a smooth installation.
    • Apply a thin layer of suspension-safe grease to the shock eyelets. This will aid in preventing squeaks and facilitate easier removal in the future.
  2. Install the Shock:
    • Carefully position the DHX2 shock in the rear triangle of the bike, aligning the mounting hardware with the shock’s eyelets.
    • Tighten the bolts using a torque wrench [paid link] to the manufacturer’s recommended specifications (usually between 150-180 in-lbs). Over-tightening can cause damage to the shock or the frame, while under-tightening may result in the shock shifting or detaching during use.
  3. Set the Air Pressure:
    • Using a Fox shock pump, adjust the air pressure to the recommended settings based on your weight and riding style. Refer to the user manual for the exact pressure settings.
    • After setting the air pressure, check that the shock does not lose air over time. If the pressure drops quickly, check for leaks around the seals.

Adjustment Tips for Optimal Performance

To get the best performance out of your DHX2 Performance Elite Rear Shock, it’s important to adjust it to suit your riding preferences and terrain. Here are key adjustments to make:

Rebound Damping

  • The rebound damping controls how quickly the shock returns after compression. Set it by turning the rebound adjuster knob (located at the base of the shock) to your desired setting.
  • If you find that the shock feels too bouncy, slow the rebound by turning the knob clockwise. If the shock feels too sluggish or “stuck,” speed up the rebound by turning the knob counterclockwise.

Compression Damping

  • The compression damping adjustment allows you to tune how much resistance the shock offers as it compresses. This is vital for controlling the bike’s handling and comfort.
  • For smoother trails or lighter riders, decrease the compression by turning the adjuster counterclockwise. For more aggressive riding or rougher trails, increase the compression by turning the adjuster clockwise.

Bottom-Out Resistance

  • The bottom-out resistance controls how much resistance the shock provides when nearing full compression. This feature is essential for preventing damage to the shock and frame during harsh landings or deep hits.
  • Adjust the bottom-out by turning the high-speed compression adjuster, typically found on the shock’s body.

Maintenance for Longevity

Regular maintenance ensures that your Fox DHX2 Performance Elite shock continues to perform at its best. Follow these tips to keep your shock in top condition:

Clean the Shock Regularly

  • After each ride, wipe down the shock body with a clean rag to remove dirt and debris. Pay special attention to the shock stanchion (the upper part of the shock) to keep the seals free from contaminants. Contaminated seals can cause friction and wear, reducing the shock’s performance.

Check for Leaks

  • Inspect the shock for signs of oil leaks or air pressure loss. If you notice any, it’s crucial to replace the seals or contact a professional for servicing.
  • Apply a small amount of suspension-specific oil to the shock’s stanchion for lubrication and to prevent wear.

Perform Annual Servicing

  • Even with regular cleaning, the DHX2 requires an annual service to ensure the seals are intact, and the shock is properly lubricated. Fox offers service kits that contain the necessary seals and fluids for servicing your shock.
  • If you’re comfortable with DIY repairs, follow the Fox service manual to replace the seals and refresh the suspension fluid. This will maintain smooth performance and prevent internal damage.

Troubleshooting Common Issues with the DHX2

Occasionally, you may encounter issues with the Fox DHX2 Performance Elite shock. Here’s how to address some of the most common problems:

Air Pressure Loss

  • If you notice a significant drop in air pressure, inspect the shock for external damage or leaks at the seals. Check the Schrader valve for tightness. If the problem persists, the seals may need to be replaced.

Excessive Rebound or Stiffness

  • If the shock feels too slow to return or overly stiff, it could be due to improper rebound damping adjustment. Experiment with the rebound settings to find the ideal balance for your riding style.

No Compression Damping

  • If the compression damping seems ineffective, check the adjustment knob for any obstructions or internal damage. Over time, seals or the damping system may wear, requiring a professional rebuild.

Customization and Optimization for Better Performance

You can optimize the Fox DHX2 Performance Elite shock for specific riding conditions and personal preferences. Here are a few ways to fine-tune your shock further:

  • Air Spring Volume Spacers: Adding or removing air spring volume spacers can adjust the shock’s progression. Use fewer spacers for a more linear feel, or add more for a more progressive feel that resists bottoming out during big hits.
  • Custom Tuning: For riders who want to take their shock setup to the next level, consider working with a suspension technician to custom-tune the internal valving and shock oil weights based on your weight, riding style, and terrain preferences.

Compatibility with Other Drivetrain Components

The Fox DHX2 Performance Elite Rear Shock is designed to be compatible with a wide range of mountain bike frames and drivetrains. However, it’s important to check compatibility with other components such as your frame’s rear triangle and linkages. The shock uses a 40mm eyelet, so verify that your frame supports this before installation.

When tuning or replacing the shock, ensure that the frame’s geometry and suspension design align with the shock’s specifications. Using an incompatible shock can lead to poor suspension performance and potential damage to your frame or shock.

Conclusion

By following these maintenance, adjustment, and troubleshooting steps, you can significantly extend the life of your Fox DHX2 Performance Elite Rear Shock. Regular servicing and customization will keep your shock performing at its peak, allowing you to enjoy smoother, more controlled rides. Whether you’re an experienced rider or a beginner, these DIY hacks will help ensure that your shock continues to deliver top-tier performance over time.
