PRELOAD SETTING

THREADED PRELOAD COLLAR

Increase

TIGHTEN collar so it moves DOWN the shock body.

Decrease

LOOSEN collar so it moves UP the shock body.

The upper and lower shock mounting positions determine how

much leverage the lower suspension arm has on the shock when

compressing it, and how progressive the suspension is. Different shock

position settings change how the shock reacts to compression.

EFFEcTS OF SHOcK POSITION adJUSTMENT

Spring preload is used primarily for adjusting ride height, and

is not used for altering camber or other suspension settings or

characteristics. Spring preload may also be used to adjust the tweak

in the car. For more information, see sections “Ride Height” and

“Tweak.”

Shocks More Inclined

Makes the spring and damping softer.

Makes the car more progressive, giving a smoother feel and more lateral grip (side-bite).

Shocks More Upright

Makes the spring and damping harder.

Makes the car have a more direct feel, but less lateral grip.
