ADJUSTMENT PROCEDURES
SETUP AND ADJUSTMENTS
Spring preload is the amount of pressure at which the spring is
held. The longer the installed length of the spring, the less the
amount of preload; the shorter the installed length of the spring,
the more the amount of preload. An increase in IFS shock spring
preload will result in an increase in ski pressure.
To adjust front spring preload on threaded adjust models, grasp
the spring and turn in a clockwise direction (as viewed from the
top of the shock) to increase the preload. Turn in a
counterclockwise direction to decrease preload.
Always set the preload equally between the right and left-side
shocks.
For the best ride the spring preload should be as low as possible.
Set the preload to use the full travel of the ski shock with
occasional light bottoming.
To determine if the suspension is using full travel, place the
shock’s jounce bumper against the shock body, then test ride the
machine.
The bumper will move on the rod in relation to the amount of
travel. For example, if the shock travel is full, the bumper will
travel the entire length of the shock rod.
To prevent excessive bottoming-out, install the next highest rate
spring, or reduce the preload on the existing spring and change
the shock valving to obtain the desired effect.
NOTE: Shock valving can only be adjusted or
changed on models that have serviceable shocks.
Alignment Bar Specifications
• DIAMETER: .623”-.625” (15.824-15.875mm)
• LENGTH: 45” (114.3cm)
• MATERIAL: C-1018
Camber
• 0 = Neutral camber. The spindle is 90_ (perpendicular)
to the ground.
• + = Positive camber. Spindle top is canted outward
from the chassis.
• - = Negative camber. Spindle top is canted inward
towards the chassis.
CAUTION
If the plastic nut is unscrewed from the threaded body
the nut will break. Always leave one thread showing
above the plastic nut or the spring coils will stack,
resulting in damage.
