Changing 32 mm FLOAT & F-Series Fork Travel

Note:  All 32 mm FLOAT and F-Series forks can be reduced to 80 mm travel by adding travel spacers. The only FLOAT or F-Series fork models that can be INCREASED in travel by removing travel spacers, for all model years, are the following:

• F29 80 mm (can be extended to 100 mm maximum travel)
• 831 100 mm (can be extended to 120 mm maximum travel)

Tip:   If you want to lengthen fork travel on a FOX FLOAT or F-Series fork other than the two models stated above, contact 1-800-FOX-SHOX or an authorized service center first to verify whether you can safely do this. Be prepared to supply the product serial number that is located on the underside of the fork crown.

CAUTION:  FOX FLOAT and F-Series forks have damper cartridges with specific travel length capacity (80 mm, 100 mm, 120 mm, 140 mm, and 150 mm). Inappropriately changing your fork to a longer travel length may irreparably damage or destroy its damper cartridge. Contact 1-800-FOX-SHOX or an authorized service center for verification. Be prepared to supply the product serial number that is located on the underside of the fork crown.

WARNING:  Changing to a longer travel beyond the specific travel of the damper cartridge will damage or destroy the cartridge, possibly leading to suspension failure. Suspension failure may cause a crash and result in property damage, SERIOUS INJURY, OR DEATH.

WARNING:   Under no circumstances can you ever increase an F-Series 80 mm or 100 mm fork to 120 mm of travel. Doing so will lead to suspension failure, resulting in property damage, SERIOUS INJURY, OR DEATH.

The following service procedure can extend from the end of the Disassembly section in the 2010 F90/F100 Fork Air Spring Quick Service page. If necessary, go there first to see how to disassemble your fork air spring assembly.

Installing Spacers to Reduce Travel

1. Slide the spring back from the air piston end of the shaft.
   
   
2. Insert a spacer as shown, to reduce spring travel by the length of that spacer. Spacers are available in three lengths:
