Installation of the DHX2 Factory Rear Shock

Preparation

Before starting the installation of the DHX2 Factory rear shock, ensure that your bike frame is compatible with the shock’s specifications, such as eye-to-eye length and stroke. Additionally, check that you have all the necessary tools and components for a smooth installation process.

Tools Required

  • 5mm Allen wrench [paid link]
  • 6mm Allen wrench [paid link]
  • Torque wrench [paid link]
  • Suspension grease
  • Shock mount hardware (compatible with your frame)
  • Isopropyl alcohol or degreaser
  • Clean rags
  • Shock pump

Step-by-Step Installation

  1. Remove the Old Shock: Begin by removing the existing rear shock from the bike frame. Use the 5mm and 6mm Allen wrenches [paid link] to undo the bolts holding the shock in place. Ensure the shock is fully detached from the frame.
  2. Clean the Mounting Points: Before installing the new DHX2, clean the shock mounting points on both the frame and the shock. Use isopropyl alcohol or a degreaser to remove dirt and grime, ensuring a smooth surface for the shock mounts.
  3. Install the DHX2 Shock: Place the DHX2 Factory rear shock onto the mounting points. Apply a small amount of suspension grease to the shock hardware to ensure smooth pivoting. Install the mounting hardware and tighten the bolts to the manufacturer’s recommended torque settings. Ensure that the shock is properly aligned and securely fastened.
  4. Set Initial Air Pressure: Using a shock pump, set the air pressure to match the rider’s weight and intended use. Start with the suggested base air pressure from the manual, and fine-tune from there based on feel.
  5. Check for Play: Once the shock is installed, check for any side-to-side play. If there is any movement, recheck the mounting hardware and tighten the bolts accordingly.

Adjustment of the DHX2 Factory Rear Shock

The DHX2 Factory rear shock offers a wide range of adjustments that can be made to tailor the suspension to the rider’s specific preferences. These adjustments allow you to dial in the shock for various riding styles, terrain types, and conditions.

Rebound Adjustment

The rebound adjuster on the DHX2 Factory allows you to control how quickly the shock returns to its starting position after being compressed. A slower rebound setting is ideal for rougher terrain where control is essential, while a faster rebound can be used for smoother trails.

  • To Adjust: Turn the rebound knob clockwise to slow the rebound, or counterclockwise to speed it up. Start with a neutral setting and test the shock to determine the best rebound speed for your riding style.

Compression Adjustment

The compression adjustment lets you fine-tune how the shock responds to impacts and bumps. The DHX2 features both high-speed and low-speed compression adjustments.

  • Low-Speed Compression: This adjustment controls the shock’s behavior during slower impacts, such as landing from jumps or riding over rough, uneven terrain.
    • To Adjust: Turn the low-speed compression dial clockwise for a firmer feel or counterclockwise for more plushness.
  • High-Speed Compression: This adjustment is for faster impacts, like hitting rock gardens or large drops. It helps prevent bottoming out by controlling how the shock compresses under rapid load.
    • To Adjust: Turn the high-speed compression dial to find the right balance between smoothness and support.

Air Spring Pressure

The DHX2 Factory allows you to adjust the air pressure in the shock to suit your body weight, riding style, and preferences.

  • To Adjust: Use a shock pump to increase or decrease the air pressure. Heavier riders or those seeking more support may need to increase the pressure, while lighter riders or those looking for a softer feel may prefer to decrease it.

Maintenance of the DHX2 Factory Rear Shock

Proper maintenance is crucial to ensuring that the DHX2 Factory rear shock performs at its best over time. Regular cleaning, inspection, and servicing will extend the lifespan of the shock and keep it performing optimally.

Regular Cleaning

  • Frequency: After every ride, especially on muddy or wet trails, clean the shock and the mounting points with a damp rag. Avoid using strong solvents that can damage the seals or cause wear to the shock.
  • Lubrication: Apply suspension grease to the mounting hardware every few rides to prevent rust and ensure smooth movement.

Servicing the DHX2 Factory

The DHX2 Factory shock requires periodic servicing to maintain its performance. Fox recommends having your shock serviced every 50-100 hours of riding, or at the end of each riding season.

  • DIY Servicing: If you have the proper tools and knowledge, you can perform basic maintenance like changing the oil and cleaning the internals. Fox provides detailed service manuals for DIY enthusiasts.
  • Professional Servicing: For more complex tasks, such as replacing seals or the air can, it is best to bring your shock to a certified Fox service center or a qualified bike shop.

Troubleshooting Common Issues

While the DHX2 Factory rear shock is built for durability and performance, like any mechanical component, it can encounter issues that affect its functionality. Here are some common problems and how to address them:

Problem: Lack of Rebound Control

  • Possible Cause: The rebound adjuster may be incorrectly set, or the shock may have an internal issue.
  • Solution: Adjust the rebound setting to ensure proper performance. If the issue persists, a full shock service might be needed to check for internal problems such as oil leaks or air can issues.

Problem: Shock Bottoming Out

  • Possible Cause: Low air pressure or improper compression settings.
  • Solution: Increase the air pressure slightly and adjust the high-speed compression setting to prevent bottoming out.

Problem: Noisy Shock

  • Possible Cause: The shock may be dirty or have insufficient lubrication on the mounting points.
  • Solution: Clean the shock and apply a small amount of suspension grease to the mounting hardware. If noise persists, check for any internal damage or need for a service.

Customization and Optimization for Better Performance

The DHX2 Factory rear shock offers numerous options for riders looking to fine-tune their suspension. Customizing your shock setup will ensure you get the most out of your ride, whether you’re racing, trail riding, or descending.

  • Fine-Tune Air Pressure: By adjusting the air pressure based on rider weight and terrain, you can achieve the ideal balance of comfort and control.
  • Compression Tuning: Experiment with the low-speed and high-speed compression settings to balance smoothness and support, particularly if you ride on mixed terrain.
  • Rebound Speed: Adjusting the rebound speed will prevent the shock from feeling too sluggish or too bouncy, depending on your riding style.

Comparison with Similar Models

The DHX2 Factory rear shock is designed for aggressive mountain biking, offering more advanced features than the standard DHX2 model. Compared to other shocks in the Fox lineup, such as the Float X2, the DHX2 is often preferred for its durability and adjustability in rougher conditions. The Float X2, however, is lighter and more suited for cross-country riding, whereas the DHX2 excels on more challenging, technical trails with its robust design.

Compatibility with Other Drivetrain Components

The DHX2 Factory rear shock is compatible with most modern mountain bike frames. However, compatibility can vary depending on the specific setup of your bike, including the type of mounting hardware and the size of the shock. Always check the specifications of your frame to ensure proper fitment.

In addition, the shock’s adjustable settings make it versatile [paid link] across a wide range of riding styles. Whether you are pairing it with a single-speed, 1x, or 2x drivetrain, the DHX2 Factory will provide a stable and controlled ride. Always ensure that your drivetrain components are also tuned and maintained for optimal performance when adjusting your shock settings.
