Understanding the 36 Performance Elite Architecture
The Fox 36 Performance Elite shares much of its internal design with the Factory series but lacks the Kashima coating. It features the GRIP2 or FIT4 damper, EVOL air spring, and adjustable rebound and compression. Recognizing the internal setup helps with correct servicing and upgrades.
Installation Overview and Considerations
Installing the 36 Performance Elite requires precise alignment and torque application. Always inspect the steerer tube length and ensure crown race compatibility with your headset. Torque values for axle and stem clamps should follow Fox’s official specs to prevent damage or unsafe setup.
When installing into a tapered head tube:
- Verify headset bearing alignment.
- Apply light grease on the crown race and lower headset cup.
- Align the fork correctly and ensure the steerer is not overcut.
- Use a torque wrench [paid link] on stem bolts (typically 5–6 Nm) and axle (19–20 Nm).
Air Spring Setup and Adjustments
Setting air pressure correctly is critical for optimal performance and rider comfort. Fox provides a pressure chart based on rider weight, but fine-tuning is essential.
Steps include:
- Deflate existing pressure via Schrader valve.
- Pump to recommended PSI.
- Perform “equalization” by compressing the fork several times.
- Adjust volume spacers if needed to increase or decrease progression.
Riders seeking a more linear feel can remove spacers, while adding them enhances ramp-up for aggressive descents.
Damper Adjustment Guide
The 36 Performance Elite comes with either GRIP2 or FIT4 dampers, each with distinct tuning options.
GRIP2 Damper:
- High- and low-speed compression adjustments
- High- and low-speed rebound
- Allows riders to fine-tune for terrain and riding style
FIT4 Damper:
- Simpler interface with Open/Medium/Firm settings
- Rebound and low-speed compression controls
- Preferred by riders valuing ease-of-use over deep tuning
Adjusting damping should be done gradually. Record original settings before experimenting and always test changes on familiar trails.
Performing Regular Lower Leg Maintenance
Lower leg service keeps the fork running smoothly and prevents premature wear. Fox recommends performing this every 30–50 riding hours.
Procedure:
- Remove the air using a suspension pump.
- Unthread lower bolts and gently slide off the lower legs.
- Drain and clean out old oil and grime.
- Inspect and replace foam rings and dust wipers as needed.
- Reapply Float Fluid and 20wt Gold oil before reinstalling lowers.
Keep workspaces clean and wear gloves to avoid contaminating internals.
Troubleshooting Common Issues
Several issues can arise if the 36 Performance Elite isn’t set up or maintained properly.
Harsh Ride or Lack of Small Bump Sensitivity:
- Check air pressure and volume spacers.
- Clean and lubricate seals.
Oil Weep or Seal Leakage:
- Worn dust wipers or overfilled lowers can cause this.
- Replace seals and check oil volume carefully.
Inconsistent Rebound or Compression:
- Air spring may not be fully equalized.
- Damper oil could be contaminated—consider full damper service.
Stiction or Fork Not Returning Smoothly:
- Indicates need for lower leg service.
- Wipers and foam rings may be dry or contaminated.
Long-Term Maintenance Intervals
To preserve the damping and air spring performance, adhere to Fox’s service schedule:
- Every 30–50 hours: Lower leg service and visual inspection.
- Every 100–125 hours or annually: Full air spring and damper rebuild.
Using Fox-specific oils and tools ensures compatibility and optimal results.
Compatibility with Other Drivetrain and Wheel Components
The 36 Performance Elite is designed around modern Boost hub standards and tapered head tubes. Ensure axle spacing matches your hub (110x15mm). The fork fits 29-inch or 27.5-inch wheels with corresponding offsets and clearances.
Brake mount compatibility is for post-mount disc brakes. Rotor size should be at least 180 mm for adequate stopping power, with adapters available for 203 mm setups.
Customization and Performance Upgrades
Several upgrades and tuning kits are available for the 36 Performance Elite:
- GRIP2 damper retrofit (for older FIT4 models)
- Air spring upgrade kits for different travel lengths
- Custom decal kits for personalization
- Custom tuning services via Fox or third-party experts
These upgrades allow riders to match the fork to changing trail demands or bike setups.
Comparing the 36 Performance Elite to Other Models
Fox 36 Factory:
- Same internals as Performance Elite
- Kashima coating offers slightly reduced stiction
- Slightly higher cost for marginal performance gain
Fox 34 Performance Elite:
- Lighter and more XC/trail focused
- Less torsional stiffness
- Not suitable for enduro or aggressive trail riding
Fox 38 Performance Elite:
- Heavier, stiffer, and built for more aggressive terrain
- Larger stanchions (38 mm vs. 36 mm)
- Ideal for heavy riders or e-MTBs
Riders should weigh priorities between weight, stiffness, and tuning depth when choosing between models.
FAQs
How often should I service my Fox 36 Performance Elite?
You should perform lower leg maintenance every 30–50 hours and a full service every 100–125 hours or annually.
Can I install the GRIP2 damper into a FIT4 36 Performance Elite?
Yes, Fox offers GRIP2 retrofit kits compatible with most Performance Elite forks. Check model year compatibility before purchasing.
Why is my fork not using full travel?
This could be due to too many volume spacers or excessive air pressure. Adjust the air spring and retest.
Can I reduce travel on my 36 Performance Elite?
Yes, travel can be reduced with an air shaft kit. This modification requires internal air spring changes and precise measurement.
What oil should I use for my lower leg service?
Use Fox 20wt Gold oil for lubrication and Float Fluid for foam rings, per manufacturer guidelines.
Is the 36 Performance Elite compatible with 27.5-inch wheels?
Yes, as long as you choose the correct fork model. Ensure your model is designed for 27.5-inch wheels and confirm axle spacing.
Conclusion
Maintaining your Fox 36 Performance Elite suspension fork at home is entirely manageable with the right tools, regular service, and attention to detail.
