Common Float DPS Performance Rear Shock Issues
1. No Rebound or Slow Rebound
One of the more common issues encountered with the Float DPS Performance rear shock is insufficient or slow rebound. This can affect the shock’s ability to return to its neutral position, leading to an uncomfortable ride.
Possible Causes:
- Incorrect rebound damping setting: If the rebound adjustment knob is set too low, the shock may rebound slowly or not at all.
- Dirty or contaminated shock internals: Dirt and grime can enter the shock and impact its ability to function properly.
- Low shock air pressure: Insufficient air pressure can lead to slow or uneven rebound.
Troubleshooting:
- Check the rebound setting: Start by adjusting the rebound knob to a higher setting. Turn the knob clockwise to increase the rebound speed and counterclockwise to slow it down. Make sure you are within the recommended settings for your weight and riding style.
- Clean the shock: Use isopropyl alcohol or a degreaser to clean the exterior of the shock. If dirt has entered the shock body, it may require more extensive maintenance, such as oil changes or a complete disassembly.
- Inspect air pressure: Use a Fox shock pump to ensure the correct air pressure for your weight and riding conditions. Refer to the manufacturer’s guide for proper pressure recommendations.
2. Sticking or Loss of Travel
If you experience a feeling of the shock being “stuck” or not compressing fully, it may be due to friction or insufficient lubrication.
Possible Causes:
- Insufficient lubrication: The shock’s internal lubrication may have deteriorated, causing excessive friction.
- Debris inside the shock: Small particles of dirt or debris can enter the shock and affect its performance.
- Damaged seals: Worn-out or damaged seals may cause friction, reducing travel.
Troubleshooting:
- Lubricate the shock: Apply Fox suspension oil to the shock’s internal components to restore proper lubrication. Be sure to use only Fox-approved oils to avoid compatibility issues.
- Clean the shock: Carefully clean the shock with a soft cloth and isopropyl alcohol, removing any dirt or debris. This may require removing the shock from the bike and inspecting it closely.
- Check seals: Inspect the shock seals for any signs of wear or damage. If the seals appear to be compromised, they may need replacement. Refer to the Fox manual for instructions on replacing seals.
3. Sag or Bottoming Out
Sag, or the shock compressing too much under load, can lead to bottoming out, where the shock hits its travel limit during compression. This issue can make the bike feel sluggish and uncomfortable.
Possible Causes:
- Incorrect air pressure: Too little air pressure can cause the shock to compress too easily.
- Incorrect spring rate: If the shock’s spring rate is too soft for your weight, it may lead to excessive sag.
- Improper shock settings: If the shock’s damping settings are not properly tuned, it may cause the shock to bottom out.
Troubleshooting:
- Adjust air pressure: Use a Fox shock pump to adjust the air pressure. Increase the pressure slightly to reduce sag, but do not exceed the recommended limits. Check your user manual for precise air pressure guidelines.
- Recalibrate settings: Adjust the compression settings on the shock. The Float DPS Performance offers separate low and high-speed compression damping adjustments, which can help fine-tune the shock’s performance. Start with the factory settings and gradually adjust as needed.
- Check spring rate: If you consistently experience bottoming out, it may be worth considering a different spring rate for your shock. Consult the Fox sizing chart to determine the best fit for your weight.
4. Air Leaks or Loss of Pressure
An air leak in the Float DPS Performance rear shock can cause a gradual loss of pressure, leading to inconsistent performance or even failure to maintain correct settings.
Possible Causes:
- Damaged valve or seals: The air valve or seals may have been compromised, leading to air leakage.
- Improper valve connection: If the shock pump is not securely connected to the air valve, it could lead to pressure loss.
Troubleshooting:
- Inspect air valve and seals: Check the air valve for any signs of damage or wear. If the seals appear compromised, they may need replacing. Fox suspension seals can be purchased separately for maintenance.
- Check for leaks: After filling the shock with the proper air pressure, apply soapy water to the valve and surrounding areas. If bubbles form, there is a leak, and you may need to replace the valve or seals.
- Use a high-quality shock pump: Ensure that the shock pump is in good condition and properly connected. A poor connection can result in loss of pressure.
5. No Lockout or Improper Lockout Function
The Float DPS Performance shock features a lockout function that helps reduce suspension movement when riding on smooth terrain. A malfunctioning lockout can lead to unnecessary suspension movement, affecting ride quality and efficiency.
Possible Causes:
- Incorrect lockout setting: If the lockout dial is set too loosely, it may fail to engage fully.
- Damaged lockout mechanism: The internal lockout components could be damaged or obstructed by dirt.
Troubleshooting:
- Check the lockout dial: Ensure that the lockout dial is turned fully to the “locked” position. If it feels loose or is not engaging, try tightening it carefully.
- Clean the shock internals: Remove the shock from the bike and clean the internal components, ensuring that no dirt or debris is interfering with the lockout mechanism.
- Inspect the lockout mechanism: If cleaning doesn’t resolve the issue, it may be necessary to inspect or replace the lockout components. This may require professional servicing if you’re not familiar with the internals.
6. Excessive Noise or Creaking
Creaking or excessive noise coming from the shock can indicate mechanical issues or misalignment.
Possible Causes:
- Loose mounting bolts: If the shock mounting bolts are not tightened to the proper torque specifications, it can result in noise during compression.
- Worn bushings: The shock’s bushings or pivot points may have worn out, leading to noise.
Troubleshooting:
- Tighten the mounting bolts: Use a torque wrench [paid link] to ensure the mounting bolts are properly tightened to the manufacturer’s specifications.
- Check bushings: Inspect the shock’s bushings for wear and replace them if necessary. Fox provides replacement bushings for their shocks.
7. Inconsistent Performance After Recent Service
If you have recently serviced your Float DPS Performance shock and are noticing inconsistent performance, it could be due to improper assembly or missed steps during maintenance.
Possible Causes:
- Incorrect reassembly: If the shock was disassembled for servicing, improper reassembly could affect its performance.
- Insufficient lubrication: If the shock was not lubricated properly during servicing, it may lead to poor performance.
Troubleshooting:
- Recheck the assembly: Ensure that all parts are correctly assembled and that no components are missing or incorrectly installed.
- Lubricate the shock internals: If the shock was serviced but lubrication was not properly applied, re-lubricate the internal components with Fox-approved oils.
By following the steps outlined above, you can resolve common issues with your Float DPS Performance rear shock and keep it functioning at its best for smooth, efficient riding. Regular maintenance and proper adjustments are key to getting the most out of your shock and ensuring a consistent riding experience.
