Fox 40 Fork Scratch Repair
Fox 40 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

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.
