Fox 831 Repairs & Custom Tuning
Compatible Fox 831 forks can also receive damper servicing, stanchion scratch repair, lower leg bushing replacement, custom damper tuning and complete-bike removal or refitting.
Fox 831 Damper Service
Fox 831 damper servicing for removable drop-in cartridges that are poorly performing through compression, rebound or lockout control. Worn or failed seals, damaged bladders or worn internal parts can cause these issues.
- Damper removed and inspected
- Damper stripped and cleaned
- Service seals and wear items replaced as required
- Fresh damper oil added
- Damper rebuilt and torqued to specification
- Damper vacuum-bled if possible
- Adjuster function checked
If the complete damper cartridge can be removed as one unit, it can be sent separately for servicing and custom tuning can be added at the same time. If not, damper servicing must be completed as part of a 100hr fork service.

Fox 831 Fork Scratch Repair
Fox 831 stanchion scratch repair for suitable damage to improve the sealing surface and reduce further seal damage.
- Damage assessed before repair
- Damaged area cleaned and prepared
- Scratch filled with epoxy
- Repair left to cure for 24 hours
- Once cured, epoxy smoothed and finished
- Stanchion sealing surface checked before use
General wear is usually not suitable for this repair, as the epoxy needs a defined scratch to bond to. We’ll assess the damage first and advise whether repair or stanchion replacement is the best option.

- New bushings installed
- Bushings sized to suit the upper assembly
- Bushing alignment checked
- Fork checked after assembly
The complete upper assembly, lower legs and axle are required so the new bushings can be correctly sized and aligned.

Fox 831 Service FAQs
Do you still service Fox 831 forks?
Yes, where the correct service parts and technical information are available. We confirm the fork generation before ordering any model-specific parts.
Can I courier my Fox 831 to CJSUSPENSION?
Yes. Book your service online, complete the service form, then use one of the courier links on our booking page to arrange tracked shipping directly to our Queenstown workshop.
Can you service or tune the Fox 831 damper?
Compatible removable FIT damper cartridges can be serviced and custom tuned. Exact suitability depends on the damper fitted to the fork.
Can you change the travel on a Fox 831?
Travel adjustment depends on the 831 generation. Some earlier versions use internal travel spacers rather than a replacement air shaft, so we confirm the fork before carrying out any travel change.
