Fox GRIP2 VVC Damper Rebuild Toolkit (2021–2024)
Everything you need to rebuild your FOX GRIP2 VVC damper, damper-only service. This version was used on 36mm, 38mm, and 40mm forks from 2021 to 2024 and includes the controversial Variable Valve Control (VVC) compression design.
This damper is technically impressive but suffers from limited compression damping. Unless you're under 120 pounds, you may need to max out both LSC and HSC settings for it to feel firm enough.
Most of the damping comes from the mid-valve. Avoid trying to revalve unless you're very experienced, it's better to switch to a GRIP2 non-VVC, GRIPX, or GRIPX2 damper for better overall performance.
Use GRIP 1–2 Seal kits. Cheap, reliable, and shipped in letter mail.
Official rebuild guide for reference: Fox GRIP2 Manual (Non-VVC, still applicable for rebound).
If you're experienced and really want to revalve your damper, you can get the full VVC tuning kit from Fluid Focus here: GRIP2 VVC Damper Tune Kit – Fluid Focus. But be warned, it's not easy and not always worth it.
- 2-in-1 GRIP Shaft Clamp
- 10mm Shaft Clamp (main GRIP damper shaft + air shafts)
- GRIP Damper Body Clamp
- If you want to open the VVC compression stack, please select the 8-10-GRIP option.
No bleed syringe required, this damper self-bleeds during assembly.
- Use Fox 4wt fluid in the damper
- Also use 4wt in the lowers on the damper side (this damper ingests oil over time)
- Do not use an adjustable wrench, use a 26–28mm chamferless socket only
- Clean shafts with isopropyl alcohol before clamping
- Do not open shim stacks unless leaking or revalving
Pro Tips
- Do not expect strong LSC-HSC performance, this damper is underdamped for heavier riders. Consider switching dampers if needed.
- Keep LSR (Low-Speed Rebound) almost fully open and adjust the rebound with the HSR if possible, it chokes the compression circuit if closed too much..
- After the damper is open and you unscrewed the sealhead using our GRIP Clamps
- How to Clamp Damper Tubes
- Start disassembly from the rebound side (10mm shaft). Remove cap and shaft together, do not lose the detent ball!
- You can remove the rebound rods from the center and unscrew the mid-valve with a 12mm wrench
- Do not open the VVC high-speed rebound mid-valve stack, just remove the bottom nut
- Grease threads, reinstall sealhead from piston side, torque everything back
-
Compression side: unscrew and pull out the compression assembly
- Replace visible seals, IFP, base valve o-ring, and optionally top thread seal
- Do not open the compression VVC shim stack
- Middle o-ring inside IFP rarely leaks, only service if absolutely necessary
- Bleed is simple: fill halfway, insert piston, stroke, top off, screw in compression assembly
- Open all adjusters fully before reassembly or bleed won’t work
- Never insert the damper shaft fully after the bleed is done, always leave 2-3cm from the top when stroking or the damper will not have enough oil inside.
