The Fox 34 Float Factory GRIP2 suspension fork stands at the forefront of trail and aggressive cross-country riding performance. Designed with precision, its advanced damper technology and structural design deliver high-end control, adjustability, and comfort. This article provides a comprehensive, expert guide to installation, adjustment, maintenance, and optimization specifically for this model. Whether you’re fitting it for the first time or tuning it for peak performance, this guide will help you get the most out of your GRIP2-equipped Fox 34.

Tools Required

  • Allen wrench [paid link] set (2–8 mm)
  • Torque wrench [paid link] with appropriate bits
  • Suspension pump
  • Crown race setting tool
  • Star nut installation tool (if using a non-threadless headset)
  • Shock oil (if performing a full damper or air spring service)
  • Isopropyl alcohol and clean rags

Installation Procedure

Proper installation is critical to ensure fork alignment, steering integrity, and optimal suspension performance. Begin by confirming the steerer tube length. If it’s too long, measure and cut it carefully to match your headset stack and stem height, allowing a few millimeters for spacers if needed.

Install the star nut or threaded insert before pressing the crown race onto the steerer tube. Slide the fork into the head tube, aligning the headset bearings and spacers, then attach the stem and tighten all bolts to the manufacturer’s recommended torque.

Before mounting the front wheel, verify that the axle inserts smoothly and tightens securely using the Kabolt-X or QR15 axle. Always align the brake caliper with the rotor by loosening the caliper bolts, squeezing the brake lever, and retightening the bolts.

Initial Setup and Adjustment

The GRIP2 damper offers high/low-speed compression and rebound adjustments, plus air spring tuning via volume spacers. Start by setting the rider’s weight-based air pressure using the Fox tuning guide or app, then fine-tune:

  • Low-speed compression (LSC): Controls chassis movement and pedaling efficiency. Set it moderately firm for climbing stability.
  • High-speed compression (HSC): Affects how the fork reacts to square-edged hits and big drops. Start mid-range and adjust softer or firmer based on terrain.
  • Low-speed rebound (LSR): Influences how the fork recovers from small bumps. Too fast causes instability; too slow feels sluggish.
  • High-speed rebound (HSR): Critical for repeated impacts and aggressive riding. Adjust to maintain control without excessive bouncing.

SAG should sit between 20–25% for trail use. Sit on the bike with gear and check fork compression. Adjust air pressure or add/remove volume spacers to dial in mid-stroke support and bottom-out resistance.

Maintenance Procedures

Routine maintenance of the 34 Float Factory GRIP2 ensures long-term performance and reliability. Keep the upper tubes clean after each ride using a damp cloth. Lubricate the dust wipers with suspension-specific fluid every 25 hours of use.

Perform lower leg service at 50-hour intervals. This involves removing the lowers, cleaning the internal components, and replacing oil and foam rings. Use 20wt Gold or specified Fox suspension fluid.

Full damper and air spring services are recommended every 125–200 hours depending on conditions. This process requires advanced tools and expertise. If you’re unfamiliar with suspension internals, it’s best handled by a certified service center.

Troubleshooting Common Setup Issues

Several common issues can arise if the fork is not set up correctly:

  • Fork feels harsh or locks up: Likely caused by excessive HSC or inadequate air pressure. Reduce HSC damping and recheck air settings.
  • Fork bottoms out easily: Too little air pressure or not enough volume spacers. Increase pressure or add a token.
  • Fork rebounds too quickly: High-speed rebound is likely too open. Close HSR slightly and retest on technical terrain.
  • Steering feels loose or imprecise: Check headset torque and axle tightness. Re-torque stem bolts and preload cap.

Address each issue methodically, making small adjustments and testing performance after each change.

Customization and Performance Optimization

To further enhance performance, the 34 Float Factory GRIP2 allows for extensive customization:

  • Volume spacers: Adjust progression without affecting initial stroke suppleness. More spacers equal firmer end-stroke.
  • GRIP2 damper tuning: Factory-level tuning allows for internal shim stack modification, but this is advanced and best left to suspension specialists.
  • Kabolt-X axle upgrade: Offers marginal weight savings and stiffness over standard QR15 axles.
  • Custom decals and finishes: Purely cosmetic but allows riders to match their fork with bike aesthetics.

Riders can also swap the air spring assembly to change travel from 130mm to 140mm or 150mm, depending on the chassis spec. Always check with Fox compatibility charts before attempting internal travel changes.

Compatibility with Other Components

The 34 Float Factory GRIP2 is designed primarily for trail and aggressive XC bikes using 29” or 27.5” wheels and Boost spacing (110mm). It fits standard tapered head tubes and works best with:

  • Tapered headsets (1 1/8” to 1.5”)
  • Boost-spaced hubs (15x110mm)
  • 180mm–203mm post-mount disc brakes

It pairs well with mid-travel trail frames (120–150mm rear travel) and drivetrains that benefit from increased front-end stability, such as SRAM GX/X01 or Shimano XT-level setups.

Avoid installing it on ultralight XC frames or DH frames not designed for the stiffness and axle-to-crown height of the 34 chassis.

Model Comparison: GRIP2 vs FIT4 and Performance Series

When compared with other forks in the Fox lineup, the GRIP2 stands out for its damping precision:

  • FIT4 damper: Simpler and lighter, ideal for riders who prefer a set-it-and-forget-it setup. It lacks the high-speed adjustments found on GRIP2.
  • Performance Series 34: Shares chassis with the Factory model but uses a less adjustable GRIP damper and black anodized stanchions instead of Kashima.
  • 36 Float GRIP2: Bigger sibling with stiffer chassis and more aggressive trail/enduro intentions. Better for heavier riders or those hitting large features.

For riders prioritizing comfort, adjustability, and superior small-bump sensitivity, the 34 Float Factory GRIP2 is the optimal choice.

Frequently Asked Questions

1. How often should I service my 34 Float Factory GRIP2 fork?
Basic lower leg maintenance is recommended every 50 riding hours, while full service (including damper and air spring) is advisable every 125–200 hours.

2. What’s the maximum rotor size compatible with this fork?
The fork supports up to a 203mm rotor using the correct adapter. It comes standard with 180mm post mounts.

3. Can I change the fork’s travel?
Yes, the travel can be internally adjusted by swapping the air spring assembly. Ensure correct parts and procedures are followed.

4. What is the difference between HSC/LSC and HSR/LSR on this fork?
These refer to high/low-speed compression and rebound adjustments, which allow fine control over how the fork handles impacts and returns to its position.

5. Can I use this fork on a non-Boost frame?
No, the 34 Float Factory GRIP2 is built for Boost hub spacing (15x110mm). Non-Boost compatibility would require different axle standards.

6. Does the GRIP2 damper require any special maintenance?
While it is sealed and low-maintenance, it should be serviced at intervals recommended by Fox (typically 125–200 hours) for peak performance.
