This shock is a popular choice for riders looking to upgrade their suspension system, thanks to its advanced technologies and adjustable features. In this article, we’ll guide you through everything you need to know about installing, adjusting, maintaining, and optimizing the Float X Factory [paid link] rear shock, as well as troubleshooting common issues.

Installation of the Float X Factory Rear Shock

Preparation

Before installing your Float X Factory rear shock, ensure you have the proper tools and follow a few safety precautions.

Tools Required:

• Torque wrench [paid link]
• 8mm and 10mm hex keys [paid link]
• Fox shock air pump
• Lubricant
• Cleaning cloth
• 3mm Allen wrench [paid link]
• 15mm wrench (for mounting hardware)

Installation Steps:

1. Remove the Old Shock: Begin by removing your old rear shock from the frame. Use the appropriate hex keys [paid link] to loosen the bolts securing the shock to the frame and the swingarm. Keep the mounting hardware for reuse if it’s compatible with the Float X Factory.
2. Inspect the Mounting Hardware: Before proceeding, inspect the mounting hardware. The Float X Factory requires a specific set of mounting components. If your existing hardware is worn or incompatible, you will need to replace it.
3. Install the Float X Factory Shock: Place the shock into its designated mounting position on the frame and swingarm. Align the shock’s mounting eyes with the frame and attach the hardware, ensuring that the shock is centered.
4. Tighten the Bolts: Using a torque wrench [paid link], tighten the mounting bolts to the recommended torque specification as indicated in the shock’s manual. Be sure to tighten the top and bottom bolts evenly to avoid misalignment.
5. Set the Sag: Before fully tightening, you’ll need to set the air pressure in the shock using the Fox shock air pump. Set the sag according to your weight and riding style. The sag should be around 25-30% of the shock’s total travel.
6. Final Check: Once the shock is securely mounted and the air pressure is set, double-check all fasteners for tightness and ensure there’s no play or movement in the shock. Test the suspension by pushing down on the frame and verifying that the shock moves smoothly.

Adjusting the Float X Factory Rear Shock

The Float X Factory rear shock offers a wide range of adjustment options that allow you to fine-tune the suspension to match your riding style and terrain. Key adjustments include air pressure, rebound, compression damping, and low-speed compression.

Air Pressure

Air pressure plays a critical role in determining the performance and ride feel of your shock. Too much air pressure can result in a harsh ride, while too little can lead to bottoming out on rough terrain.

• Use a Fox shock air pump to add or reduce air pressure.
• Start with the recommended settings based on your rider weight and adjust from there.
• Check the sag after each adjustment to ensure proper setup.

Rebound Damping

Rebound damping controls how quickly the shock returns to its original position after compression. Adjusting the rebound allows you to fine-tune the suspension for different types of terrain.

• Turn the rebound dial on the bottom of the shock clockwise to slow down the rebound or counterclockwise to speed it up.
• Start with a middle setting and make small adjustments based on the terrain you’re riding.

Compression Damping

Compression damping controls the shock’s resistance to compression under load. The Float X Factory features both high and low-speed compression adjustments.

• Low-speed compression affects the shock’s response at lower speeds and on smoother terrain. Turn the low-speed compression dial to increase or decrease the damping.
• High-speed compression is for faster, more aggressive impacts. Adjust this setting if you find the shock is bottoming out during fast, hard hits.

Setting the Fine-Tuning Adjustments

Fine-tuning is essential for optimizing performance. After adjusting the main settings, take your bike out for a ride, paying attention to how the shock performs under different conditions. Make further adjustments as needed, keeping in mind that small changes can have a big impact on performance.

Maintenance of the Float X Factory Rear Shock

Routine maintenance is crucial for keeping your Float X Factory rear shock in top condition. Proper maintenance ensures longevity and consistent performance.

Cleaning and Lubrication

• Clean the shock regularly with a soft cloth to remove dirt and debris.
• Check the shock’s seals for wear and tear, especially after muddy or wet rides.
• Apply a small amount of lubricant to the shock’s shaft and seals to prevent friction.

Air Pressure Checks

Check the air pressure in the shock regularly, particularly before rides. Air can leak over time, which will affect the suspension’s performance. Adjust the air pressure as necessary, based on your weight and riding conditions.

Rebound and Compression Adjustments

Inspect the rebound and compression adjustments periodically. If you notice the shock isn’t reacting as expected, adjust the dials to restore performance.

Service Intervals

Fox recommends having the Float X Factory rear shock serviced every 100-150 hours of riding or annually, whichever comes first. Regular servicing helps keep the shock functioning smoothly and prevents major failures.

Troubleshooting Common Issues

While the Float X Factory rear shock is a high-performance component, like any mechanical part, it may experience some issues over time. Here are some common problems and troubleshooting tips:

Shock Bottoming Out

If the shock bottoms out on rough terrain, it may indicate insufficient air pressure or incorrect compression settings.

• Check Air Pressure: Make sure the air pressure is appropriate for your weight and riding style. Increase the pressure slightly if necessary.
• Adjust Compression Damping: Increase the low-speed compression to resist bottoming out.

Excessive Rebound

If the shock rebounds too quickly, it can lead to a jarring, uncomfortable ride. This can often be solved by adjusting the rebound damping.

• Slow Down the Rebound: Turn the rebound dial clockwise to slow the rebound and provide more control.

No Suspension Movement

If you notice the shock isn’t moving or compressing at all, it could be due to too much air pressure, a damaged seal, or an internal problem.

• Check the Air Pressure: Reduce the air pressure slightly to ensure the shock is able to compress.
• Inspect for Leaks: Check the shock’s seals for damage and replace if necessary.

Customizing and Optimizing the Float X Factory Rear Shock

The Float X Factory rear shock is highly customizable, allowing riders to optimize it for their specific needs. The wide range of adjustments and features enables fine-tuning for various types of riding, including cross-country, trail, and downhill.

Adjusting for Riding Style

• Cross-Country Riding: For lighter, faster rides, set the shock to a lower air pressure and softer compression damping. This setup provides better traction and comfort over longer distances.
• Trail Riding: Increase air pressure slightly and adjust the compression damping to handle a wider variety of terrain without bottoming out.
• Downhill Riding: For aggressive, fast rides, increase both the air pressure and high-speed compression damping to prevent bottoming out on rough landings and maintain control during high-impact scenarios.

Using Volume Spacers

Volume spacers can be added to the Float X Factory to adjust the shock’s progression. These spacers limit how much the shock compresses at the end of its travel, helping to prevent bottoming out on bigger hits. Experiment with different configurations to find the ideal setup for your riding style.

Compatibility with Other Drivetrain Components

The Float X Factory rear shock is designed to be compatible with a wide range of mountain bike frames and drivetrain systems. However, it’s essential to ensure that the shock’s specifications match your bike’s geometry and intended use.

• Frame Compatibility: The Float X Factory is compatible with most modern frames that support a 200mm or 210mm shock length. Always check your frame’s specifications before installation.
• Drivetrain Integration: The shock works well with a variety of drivetrain setups, including SRAM and Shimano systems. However, when choosing components, ensure that your frame’s geometry and suspension system are aligned with the specifications of the shock.

By understanding the Float X Factory’s key features and adjusting it to suit your needs, you can dramatically improve your bike’s handling and performance, whether you’re cruising through a cross-country trail or tackling the most technical downhill tracks.
