Spring preload adjustment can be used to fine tune sag, but preload does not change spring
rate and is not a substitute for the proper coil spring weight.
If the proper sag cannot be acheived after external preload adjustment, the coil spring
assembly must be replaced with a softer or firmer spring.
To
increase
sag, install a
softer
coil spring assembly.
To
decrease
sag, install a
firmer
coil spring assembly.
Repeat the sag process until your target sag percentage is achieved.
External spring

without initiating travel.
Turn the preload adjuster knob
clockwise

increase

decrease
sag.
Turn the preload adjuster knob
counter-
clockwise
