Adjustments made independently between front and rear may be required to rectify symptoms.
Incorrect spring rates may also contribute to symptoms.

Harsh Ride
Too much LSC Damping
Decrease LSC
damping. IF LSC is at
minimum reduce HSC
damping
Too much Rebound
damping
Decrease rebound
damping
Suspension never bottoms out,
not using all available travel
Too much Compression
Damping
Decrease HSC
damping. IF HSC is at
minimum reduce LSC
damping
Suspension Bottoms Out
Frequently
Too little HSC Damping
Increase HSC
Damping. If HSC is at
max slowly increase
LSC
Excessive Body Movements
Pitch/Dive/Roll/Wallow/Continu
es to bounce after larger bumps
Too little LSC Damping
Increase LSC
Damping. If LSC is at

HSC
Too little Rebound
Damping
Increase Rebound

Suspension Frequently Tops Out
Too little Rebound
Damping
Increase Rebound
damping
Suspension Packs Down in
repetitive bumps/corrugations
Too much Rebound
damping
Decrease rebound
damping
Steering Skittish and Unstable,
loss of traction on
corners/corrugation
Too much Rebound
damping
Decrease rebound
damping. If still
unstable reduce LSC
damping
Rear end bucking/kicking up on
large bumps / mounds
excessively
NOTE: In most regular 4wd and
production vehicles it may not
be possible to fully rectify due to
the factory vehicle weight
distribution and suspension
geometry
This may also be a combination of the below
Too little Rear Rebound
Damping
Increase Rear
Rebound damping
Too Much Front Rebound
Damping
Decrease Front
Rebound damping
Too Much Rear
Compression Damping
Decrease HSC
damping. IF HSC is at
minimum reduce LSC
damping
Bouncing off Bump Stops Increase HSC damping
