Tools Required
- Allen wrench [paid link] set (2mm to 8mm)
- Torque wrench [paid link] (2–20 Nm range)
- Crown race setting tool
- Star nut setter or OneUp EDC tool
- Suspension-specific grease and torque paste
- Shock pump (for air spring setup)
- Calipers (for checking rotor size and spacing)
- Isopropyl alcohol and clean cloths
Installation Guide for the Fox 36 Factory GRIP2
Installing the 36 Factory GRIP2 involves precision and the correct tools to ensure optimal performance and safety. This fork uses a tapered steerer and is compatible with 110mm Boost spacing.
First, ensure the steerer tube is cut to the proper length for your frame and headset stack. The crown race must be installed correctly without damage. Torque settings must be followed closely when securing the fork into the headset and tightening the stem and top cap.
Install the front brake caliper and rotor with the correct adapter if needed. The 36 Factory is compatible with 180mm rotors direct mount and up to 203mm with adapters. Always check rotor clearance before test riding.
Initial Setup and Adjustment of the GRIP2 Damper
The GRIP2 damper offers high and low-speed compression and rebound adjustments. Start by setting sag based on body weight using the air spring chart provided by Fox. Aim for 20–30% sag depending on your riding style.
Once sag is set:
- Adjust the low-speed rebound to control how the fork returns after slow impacts.
- Set high-speed rebound to tune the response over rapid hits or jumps.
- Dial in low-speed compression to prevent diving under braking or cornering.
- Use high-speed compression to control harsh bottom-outs.
Begin with the factory-recommended settings and adjust based on terrain feedback during test rides. Document settings as a baseline.
Maintenance Schedule and Procedures
Regular maintenance preserves the performance and lifespan of the GRIP2 damper and 36 Factory chassis. Fox recommends the following service intervals:
- Every 30 hours: Clean stanchions and inspect seals. Re-lube dust wipers with suspension grease.
- Every 100 hours: Lower leg service. Replace oil and clean air spring assembly.
- Every 200 hours or annually: Full damper and air spring overhaul. This includes damper bleed and replacing internal seals.
Use only Fox-approved fluids and tools to prevent damage. If you’re unfamiliar with internal damper service, consult a certified suspension technician.
Troubleshooting Common Setup Issues
Several issues may arise during initial setup:
- Harsh ride: Check air pressure and reduce high-speed compression.
- Fork not using full travel: May indicate too much air pressure or excessive high-speed compression damping.
- Excessive dive: Adjust low-speed compression or increase air spring volume with volume spacers.
- Knocking sounds: Could result from loose headset, axle, or internal damper issues. Inspect and tighten as needed.
Always recheck torque settings after initial rides to ensure bolts remain secure.
Performance Tuning and Customization
The Fox 36 Factory GRIP2 allows for deep customization. Riders can fine-tune travel with internal spacers, modify ramp-up with air volume spacers, and tailor damper settings for specific trails.
Additionally, the GRIP2 damper offers truly independent high- and low-speed tuning, which provides a competitive edge on variable terrain. Riders who enjoy experimenting can create a fork feel that’s unique to their riding style.
Adding aftermarket bolt-on fenders, ti bolts for weight reduction, or a custom decal kit enhances both function and aesthetics.
Compatibility with Other Drivetrain and Wheel Components
The 36 Factory GRIP2 is designed with Boost spacing (15x110mm) and a 44mm or 51mm rake depending on the model year. It’s compatible with 27.5” or 29” wheels, depending on the variant.
Ensure your front hub matches the axle standard. Brake compatibility supports post-mount calipers and rotor sizes up to 203mm. Tire clearance is generous, fitting most trail tires up to 2.6”.
For drivetrains, no direct compatibility issue exists, but cable routing and cockpit controls should be considered, especially with handlebar-mounted lockouts or wireless systems.
Comparing the 36 Factory GRIP2 to Other Forks
The 36 Factory GRIP2 stands out in terms of tuning options, ride feel, and build quality. Compared to:
- Fox 36 Performance Elite: Same chassis but lacks the high-end Kashima coating and GRIP2 damper, using the simpler GRIP damper instead.
- RockShox Lyrik Ultimate: Similar adjustability with the Charger 3 damper but features a different damping feel—more linear and supple off the top.
- Öhlins RXF36 m.2: Known for its coil-like small bump sensitivity but heavier and less tunable than the GRIP2.
For riders who prioritize customization and descending control, the 36 Factory GRIP2 offers superior adjustability and support.
Is the 36 Factory GRIP2 Worth the Investment?
Considering its advanced damping system, top-tier construction, and exceptional adjustability, the 36 Factory GRIP2 justifies its price for serious riders. It delivers unmatched front-end support on steep, technical terrain and allows riders to dial in settings for every trail condition.
Recreational riders may find value in more budget-friendly models, but for those pushing limits or racing, this fork offers performance that can significantly enhance ride quality and control.
Frequently Asked Questions (FAQs)
1. Can I install the Fox 36 Factory GRIP2 on a non-Boost frame?
No, the 36 Factory GRIP2 is designed for Boost spacing (15x110mm). It won’t be compatible with non-Boost frames without adapters, which are not recommended.
2. How often should I perform maintenance on the GRIP2 damper?
Routine lower leg service every 100 hours and a full damper overhaul every 200 hours or annually is recommended for optimal performance.
3. What volume spacers come pre-installed in the 36 Factory GRIP2?
Fox usually installs 1–2 spacers based on travel length. Check the official fork tuning guide to confirm.
4. Does the GRIP2 damper lock out fully?
No, the GRIP2 does not have a firm lockout. It offers firm low-speed compression but remains active for traction.
5. Is the Kashima coating just cosmetic?
No, the Kashima coating reduces friction, enhances durability, and improves small bump compliance compared to standard anodized finishes.
6. Can I swap the air spring to change travel?
Yes, the 36 Factory supports travel adjustment by swapping the air shaft assembly. It must match the correct wheel size and fork chassis.
Conclusion
The Fox 36 Factory GRIP2 is a high-performance fork that rewards riders who demand advanced tuning and rugged reliability. With its broad adjustability, superior damping, and race-proven pedigree, it’s an investment that pays dividends in confidence, speed, and trail control. For riders committed to pushing their limits, this fork is a worthy upgrade that elevates the entire ride experience.
