   If you’re replacing an old shock, first remove it by loosening the bolts on the shock mount with an 8mm Allen wrench [paid link]. Ensure you support the shock with one hand while loosening the bolts to prevent the shock from falling or causing damage.
3. Install the New Float SL Performance Rear Shock
   Place the new shock into the mount with the correct orientation. Attach the top and bottom mounting bolts, ensuring they align correctly with the shock’s eyelets. Tighten the bolts using a 5mm Allen wrench [paid link], and be sure to follow the recommended torque settings listed in the product manual to avoid over-tightening or under-tightening.
4. Check for Proper Clearance
   Once the shock is secured, check for any interference between the shock and frame. Ensure that the shock moves freely through its full range of motion without obstruction.
5. Inflate to Recommended Pressure
   Using the shock pump, inflate the Float SL Performance to the recommended pressure based on your weight and riding style. Refer to the shock’s specifications for precise air pressure settings.
6. Test the Installation
   Before heading out for a ride, perform a static test by pressing down on the bike’s saddle and watching the shock compress. This helps confirm that the shock is functioning correctly and is properly mounted.

Adjusting the Float SL Performance Rear Shock

The Float SL Performance Rear Shock comes with several adjustable features that allow riders to fine-tune the suspension to their specific needs. Adjusting the shock for optimal performance involves tweaking air pressure, rebound, and compression settings.

Air Pressure Adjustment

The air pressure in the Float SL Performance is critical for ensuring the shock works effectively under different riding conditions. To adjust the air pressure:

• Use a shock pump to add or release air based on your weight, riding style, and terrain.
• Refer to the shock’s manual for recommended air pressure ranges.
• Keep in mind that higher pressure is typically needed for heavier riders, while lighter riders may need less.

Rebound Adjustment

Rebound controls how quickly the shock returns to its original position after compression. To adjust rebound:

• Locate the rebound adjuster, typically a red or black knob at the bottom of the shock.
• Turning the knob clockwise slows down rebound, while turning it counterclockwise increases the rebound speed.
• Test the rebound settings by compressing the shock and observing how it returns. The goal is to achieve a balance where the shock doesn’t return too quickly or too slowly.

Compression Adjustment

The compression adjustment affects how the shock reacts to impacts. There are typically two settings: low-speed compression and high-speed compression.

• Low-speed compression affects the shock’s behavior during slower, more controlled movements such as climbing or riding on smoother terrain.
• High-speed compression influences how the shock performs under faster, more aggressive impacts, such as hitting a rock or a jump.

Adjust these settings to your preference by turning the compression knob or dial (usually located near the shock’s air valve).

Maintaining the Float SL Performance Rear Shock

Proper maintenance is crucial to keep your Float SL Performance Rear Shock working at its best. Follow these guidelines to ensure the longevity and reliability of your shock:

1. Regular Cleaning
   After each ride, especially in muddy or wet conditions, clean the shock with a damp rag. Remove any dirt or debris from the shock’s seals and body to prevent wear and tear. Be careful not to damage the air valve or adjustment knobs while cleaning.
2. Inspect the Seals
   The shock’s seals protect the internal components from dirt and moisture. Periodically inspect the seals for signs of wear or damage. If you notice any issues, consider replacing the seals to maintain optimal shock performance.
3. Check for Leaks
   If you notice a loss of air pressure, the shock may be leaking. Check for air leaks by spraying a soapy water solution around the air valve and seals. If bubbles form, it’s a sign that the shock may need servicing.
4. Rebuild and Service
   Fox recommends servicing the Float SL Performance every 50-100 hours of ride time. During the service, the internals should be inspected, and any worn parts should be replaced. Consider sending the shock to an authorized Fox service center for this process.

Troubleshooting Common Set-Up Issues

Despite its high performance, the Float SL Performance Rear Shock may occasionally present set-up issues. Here are some common problems and solutions:

1. Shock Not Compressing Properly
   • Check the air pressure and adjust it according to your weight and riding style.
   • Ensure that the shock mount is properly installed and there are no obstructions.
2. Rebound or Compression Not Functioning Correctly
   • Revisit your rebound and compression adjustments. Make small changes and test the shock’s performance before making further adjustments.
   • If the settings are not responsive, check for oil leaks or damage to the internals, which may require a professional rebuild.
3. Noise During Compression
   • Some noise is normal, but excessive noise could indicate a problem. Clean the shock thoroughly, and inspect the seals for wear. If the noise persists, the shock may need servicing.

Customization and Optimization for Better Performance

One of the standout features of the Float SL Performance Rear Shock is its ability to be customized for varying riding conditions. To optimize the shock for better performance:

• Fine-tune the air pressure to suit your riding style and terrain. Riders who frequently tackle rocky, technical trails may want a firmer setup, while those who enjoy smoother rides may prefer a softer feel.
• Adjust the rebound and compression settings to match your needs. If you ride aggressively or tackle large drops, higher compression and slower rebound settings will provide better control.
• Use a custom shock tune if you’re looking for a specific ride feel. Fox provides custom shock tuning services, allowing riders to receive a shock that is fine-tuned to their unique needs.
