terms 

used

suspEnsiOn

compression

: downward travel of the suspension. actions that move the endpoints of the shock closer together.

compression damping

: oil damping resistance felt when trying to compress the shock. 

emulsion shock

: shock without an IFp (Internal Floating piston) separating the oil and nitrogen.

frame clearance

: distance between the frame and other moving parts, like the shock.

negative travel

: distance the suspension or shock extends from the static ride height. also referred to as ‘free 

sag’. 

preload

: initial force on the spring. preload is used to adjust rider sag.

ride height

: with the rider on the bike, the basic stance of the bike. usually measured from the ground to some 

point on the bike frame. 

rebound

: force required to extend the shock or suspension. can also refer to the extending action of the 

suspension.   

rebound damping

: oil damping resistance that controls the rate at which the shock extends after being 

compressed. 

rider sag

: amount the shock compresses with the rider sitting on the atv in a normal riding position. 

free sag:

 amount that the atv “sits” into travel. usually measured from the ground to a point on the frame, or as 

shock stroke, and without a rider on the atv. 

spring rate

: force required to compress a spring one inch. measured in lb/in. or kg/mm.

stroke

: amount of shock travel. 

travel

: total amount the shock compresses, as measured from eye-to-eye.

Valving

: refers to the combination of shims or damping valves on the piston face used to achieve a specific ride 

characteristic.

wheel travel

: distance the wheel moves when the suspension is cycled through its full travel. 

ridinG

bottoming:

 vehicle has bottomed-out when the suspension reaches the limit of its travel and stops further 

downward motion.

bucking

: kicking motion on a rider after a bump or jump landing. 

chatter

: small bumps similar to braking bumps prior to a corner or berm. often refers to the harshness felt when 

riding over small, closely spaced bumps.

fading

: slow loss of shock damping usually due to heat. 

packing

: when the shock does not return quickly enough to adequately absorb the next bump in a repetitive 

bump sequence.

spiking

: sharp impact cause by a square-edge bump. 

squat

: when the rear of the vehicle “sits” down either due to weight transfer or driveline forces. 

stiction

: initial force that needs to be overcome to start the suspension stroke.

topping-out

: when the suspension is fully extended.

service 

intervals

before every ride

: wipe mud and debris off shock exterior and check air pressures

monthly

: clean and inspect your shock. make sure the air sleeve is threaded on properly. 

Annually

: clean and inspect your shock. see the 

mAintAining the floAt x eVol 

section on page 16 of this manual.  

every ride season

: shock rebuild by a FoX certified technician or FoX Racing shox
