Damping Adjustment (if equipped)
Your FOX shock has up to two External Damping Adjustments – rebound damping and compression
damping. Rebound damping controls how quickly the shock extends after hitting a bump – more
rebound damping means slower extension.
Compression damping controls how quickly the
shock compresses in response to a bump. More
compression damping means the shock is more
difficult to compress.
The blue knob at the lower end of the shock
absorber is the rebound adjuster and has
approximately 25 positions (see Figure 2). The
position of maximum rebound damping is when the
knob is turned all the way up towards the main body
of the shock until it stops. Do not attempt to force
the knob after it stops turning. To check the
rebound damping setting, always count the number
of clicks as you turn the knob to maximum
damping. For example, setting rebound damping “8
clicks out” means turning the rebound damping
knob all the way towards the shock body until it
stops, then turning it 8 clicks back.
Default rebound damping setting: 10 clicks out
The red knob on the reservoir is the compression damping knob and has 8 settings – with 1 being soft
and 8 being hard. The numbers line up with a notch on the reservoir.
Default compression damping setting: #3
Tuning Instructions
Now that you have the spring preload and shock length set correctly, it is time to tune the shock to your
liking. It is vital that the spring preload be set correctly before any damping changes are made –
otherwise you will be starting from a faulty baseline and will have difficulty getting the shock to work
properly.
Spring Preload
You might want to experiment with different sag settings to suit your own personal riding style. The
settings that you like will also change from bike to bike, and from track to track if you race. Also,
different tires make a difference in the settings that you prefer.
Try keeping a note book and experimenting with different set-ups; you will see differences in how your
bike steers: more
rider sag will make it steer “slower”, less rider sag will make it steer “quicker”.
Ride Height / Shock Length Adjustment (if equipped)
The overall length of some FOX shocks can be adjusted. This adjustment changes the ride height and
can provide a useful tuning tool.
