The Fox 36 Factory GRIP2 is a premium enduro and trail suspension fork designed for aggressive riders seeking maximum control, adjustability, and performance. Its sophisticated GRIP2 damper offers a wide range of compression and rebound settings that cater to various riding styles and terrains. To maintain the high performance and longevity of your 36 Factory GRIP2 fork, understanding its installation, tuning, and maintenance procedures is essential. This guide offers step-by-step instructions and troubleshooting tips to help you handle everything at home with precision and confidence.

Tools Required

  • 5 mm and 6 mm hex wrenches
  • Torque wrench [paid link] (with Nm scale)
  • Suspension pump
  • Clean rags
  • Suspension-specific grease (e.g., Slick Honey)
  • Isopropyl alcohol
  • Plastic tire lever or soft pick
  • Fork seal driver kit
  • 10 mm socket or wrench
  • Oil syringe (for bath oil replacement)
  • FOX 20wt Gold bath oil
  • FOX Float fluid (if air spring service is needed)

Installing the 36 Factory GRIP2 Fork

Proper installation ensures optimal fork function and rider safety. Begin by checking headset compatibility and fork steerer tube length.

The fork’s steerer must be cut to match your frame and headset. After cutting, install a star nut using the proper alignment tool. Insert the fork through the head tube, and stack spacers and stem accordingly. Torque the top cap and stem bolts to manufacturer specifications, ensuring the headset preload is snug but not restrictive.

The 36 GRIP2 is compatible with both 15QR and 110mm Boost front axles. Insert the axle through the hub and fork dropouts, and tighten it to the specified 19 Nm to ensure front wheel security. Double-check brake rotor clearance and alignment before test riding.

Setting Up the GRIP2 Damper and Air Spring

To achieve peak performance, setting the correct air pressure and damping is crucial. Begin by referencing Fox’s rider weight pressure chart to set your baseline air pressure using a suspension pump. Always equalize the positive and negative chambers by cycling the fork gently through its travel after inflation.

The GRIP2 damper features four independent adjustments:

  • High-Speed Compression (HSC)
  • Low-Speed Compression (LSC)
  • High-Speed Rebound (HSR)
  • Low-Speed Rebound (LSR)

Start with Fox’s baseline settings:

  • HSC and HSR at 6 clicks out from fully closed
  • LSC and LSR at 8 clicks out

Adjust based on terrain and personal preference. Firmer compression settings increase support for aggressive riding, while slower rebound enhances traction over rough surfaces. Recheck settings regularly, especially after changes in riding conditions.

Routine Maintenance Schedule

Regular maintenance extends the life of the fork and maintains optimal sensitivity.

Every 30 hours of riding:

  • Clean stanchions and dust wipers with isopropyl alcohol.
  • Inspect for oil residue, which may indicate seal wear.
  • Lubricate seals with Float Fluid externally.

Every 50 hours of riding:

  • Replace bath oil in the lower legs.
  • Inspect foam rings and dust wipers; replace if necessary.

Every 100 hours or annually:

  • Perform full air spring and damper service.
  • Replace seals, O-rings, and lubricants as per Fox specifications.

Always record maintenance intervals and findings in a log for tracking fork performance over time.

Troubleshooting Common Set-Up Issues

Certain symptoms can arise from improper setup or component wear:

  • Fork feels harsh over small bumps: Check air pressure. It may be too high. Also verify rebound is not set too fast.
  • Fork dives excessively under braking: Increase LSC or add volume spacers to increase mid-stroke support.
  • Noise during compression: Often a sign of low bath oil or air trapped in damper. Replacing oil usually resolves this.
  • Oil leaking around dust seals: Replace seals and check stanchions for damage.

Use a process of elimination, adjusting one parameter at a time to identify the root cause.

Customizing Suspension Feel with Volume Spacers

Volume spacers adjust air spring progression. More spacers result in a firmer, more progressive stroke, ideal for aggressive descents. Fewer spacers soften the ramp-up for a plusher feel over long travel.

The 36 Factory typically comes with 2 or 3 spacers installed. To modify:

  • Release air from the fork.
  • Remove the top cap with a 6 mm hex.
  • Add or remove spacers based on desired feel.
  • Reassemble and torque the cap to 28 Nm.

Always re-pressurize and equalize after volume tuning.

GRIP2 Damper Performance Optimization

The GRIP2 damper offers exceptional tunability, but precision setup is key. Advanced riders can fine-tune:

  • HSC for bottom-out resistance on drops.
  • LSC for mid-stroke support during pedaling.
  • HSR for recovery speed on high-impact hits.
  • LSR for terrain tracking over chattery surfaces.

Use a data-logging app or notepad to test click-by-click changes across trail types. Dialing in your damping can drastically improve ride quality and reduce fatigue.

Comparison with Similar Forks

Compared to the Fox 36 Performance Elite or RockShox Lyrik Ultimate, the 36 Factory GRIP2 stands out with:

  • Kashima-coated stanchions for enhanced durability and reduced friction.
  • More precise damper control with independent high- and low-speed compression and rebound adjustments.
  • Lightweight yet stiff chassis ideal for aggressive riders.

While the Performance Elite shares internals, it lacks the premium coating. The Lyrik offers comparable performance but has fewer adjustability options.

Compatibility with Other Components

The 36 Factory GRIP2 is designed to integrate seamlessly into modern trail and enduro setups:

  • Compatible with Boost-spaced hubs (15×110 mm).
  • Steerer tube fits tapered headsets (1.5” to 1-1/8”).
  • Works with 180 mm to 203 mm post-mount brake rotors.
  • Maximum tire clearance supports up to 2.6” tires.

Ensure your wheelset, brakes, and frame geometry align with these specs before purchase or installation.

FAQs

How often should I service the Fox 36 Factory GRIP2 fork?
Service intervals are every 50 hours for bath oil and 100 hours for full damper and air spring maintenance. Light cleaning can be done after every ride.

Can I adjust the GRIP2 damper settings on the trail?
Yes, the external adjusters allow on-the-fly tuning. Just make small changes and test each one individually.

What air pressure should I use in my Fox 36?
Refer to Fox’s rider weight chart. A typical starting point is 80–90 psi for riders around 75 kg. Adjust based on feel and sag measurement.

Is the 36 Factory GRIP2 better than the Performance Elite?
They are mechanically similar, but the Factory model has a Kashima coating, which enhances durability and small bump sensitivity.

Can I install the 36 Factory fork on a hardtail?
Yes, as long as the head tube and axle specs match. It may change the bike’s geometry, so verify trail and rake effects.

What tools do I need to service the fork at home?
You’ll need suspension-specific tools like a torque wrench [paid link], oil syringe, seal drivers, and Fox-approved lubricants and fluids.

Conclusion

Maintaining the Fox 36 Factory GRIP2 at home is entirely achievable with the right tools and knowledge. Whether you’re fine-tuning damping for a specific trail or performing scheduled oil service, each step ensures peak fork performance and durability. Precision setup and consistent maintenance unlock the full potential of your suspension, offering the confidence and control needed for every ride.
