Introduction
This manual provides essential information for the proper setup, operation, and maintenance of your FOX FLOAT DPS FACTORY rear shock, model 972-01-497. Designed for optimal performance on various terrains, this rear shock features an EVOL air spring and a Dual Piston System (DPS) damper for superior control and responsiveness. Please read these instructions carefully before installation and use to ensure safe and effective operation.
Key Features
- FLOAT DPS Factory Rear Shock: High-performance rear suspension unit.
- Dual Piston System (DPS) Damper: Improves both rebound and compression flow for enhanced control.
- Lightweight, One-Piece EVOL Air Sleeve: Enhances responsiveness and sensitivity over small bumps.
- 3-Position Switch: Allows quick adjustment between Open, Medium, and Firm modes to adapt to riding conditions.
- Genuine Kashima Coat: Factory Series models feature this low-friction, highly durable coating for improved performance and longevity.
Setup
Proper setup is crucial for optimal performance and rider safety. Consult your bicycle manufacturer's recommendations for specific mounting and torque specifications.
1. Air Pressure Adjustment (Sag)
The EVOL air spring requires precise air pressure to achieve the correct sag. Sag is the amount the suspension compresses under the rider's weight. Refer to your bike manufacturer's guidelines for recommended sag percentages (typically 25-30% for trail riding).
- Attach a high-pressure shock pump to the air valve.
- Slowly add air in 50 psi increments, cycling the shock through its travel after each addition to equalize positive and negative air chambers.
- With riding gear, sit on the bike in a normal riding position. Have someone measure the shock's travel to determine sag.
- Adjust air pressure until the desired sag is achieved. Do not exceed the maximum air pressure listed on the shock body or in the specifications section.
2. Rebound Adjustment
Rebound controls the speed at which the shock extends after compression. The red dial on the shock body adjusts rebound damping.
- Turn the red dial clockwise for slower rebound (more damping).
- Turn the red dial counter-clockwise for faster rebound (less damping).
A good starting point is to turn the dial fully clockwise until it stops, then turn it counter-clockwise 6-8 clicks. Fine-tune based on riding preference and terrain.
3. Compression Adjustment (3-Position Lever)
The blue 3-position lever adjusts the low-speed compression damping, allowing you to optimize the shock's performance for different riding conditions.

Operating Instructions
The DPS damper features three distinct compression modes, selectable via the blue lever:
- Open Mode: Provides full suspension travel and maximum bump absorption. Ideal for aggressive downhill riding and technical trails.
- Medium Mode: Offers increased compression damping for improved pedaling efficiency and control on undulating terrain. Suitable for general trail riding.
- Firm Mode: Maximizes pedaling efficiency by significantly firming up the suspension. Best for climbing, smooth fire roads, or paved sections.
Switch between modes as needed to match the terrain and your riding style. It is recommended to make adjustments while stationary or during a brief pause in riding.
Maintenance
Regular maintenance ensures the longevity and performance of your FOX FLOAT DPS FACTORY rear shock.
- Cleanliness: After every ride, wipe down the shock body and shaft with a clean, soft cloth to remove dirt and debris. Pay special attention to the Kashima-coated surfaces.
- Lubrication: Do not use spray lubricants or solvents on the shock shaft or seals, as this can damage the seals and internal components. The Kashima coat is designed to be self-lubricating.
- Air Pressure Check: Check air pressure before every ride and adjust to your preferred sag setting.
- Service Intervals: FOX Factory recommends regular service by an authorized service center. Consult the FOX Factory website for detailed service schedules based on riding conditions and hours of use.
- Inspection: Periodically inspect the shock for any signs of damage, leaks, or unusual wear. If any issues are found, discontinue use and contact an authorized service center.
Troubleshooting
This section addresses common issues you might encounter with your rear shock.
| Problem | Possible Cause | Solution |
|---|---|---|
| Loss of air pressure / Excessive sag | Leaking air valve, damaged air sleeve seals, improper air pressure setting. | Check air valve for tightness. Re-inflate to correct pressure. If problem persists, an air sleeve service or seal replacement may be required by an authorized technician. |
| Poor damping performance / "Pogo stick" feel | Incorrect rebound setting, low air pressure, internal damper issue. | Adjust rebound damping (red dial). Verify correct air pressure. If issues persist, professional service is recommended. |
| Shock feels harsh / Not using full travel | Too much air pressure, compression setting too firm. | Reduce air pressure to achieve correct sag. Ensure compression lever (blue) is in "Open" or "Medium" mode for appropriate riding conditions. |
For issues not listed here or if solutions do not resolve the problem, please contact FOX Factory customer support or an authorized service center.
