Judy forks are designed to be nearly maintenance free. However, as long as moving parts are exposed to the
elements, moisture and contamination can reduce performance. To maintain high performance, safety, and
long life, periodic maintenance is required. RockShox forks are engineered for easy service to help you keep
the fork clean,greased, and performing like new. Performing maintenance more often is necessary if you ride
in extreme conditions. The recommended tools and intervals for maintenance are listed below.

o Change Preload:
The top cap adjustment knob on each leg adjusts the sag of the fork (the preload on the
spring stack). When the adjustment knobs are turned full clockwise, the fork will sag the least and be the
firmest. Turning the adjustment knobs full counterclockwise makes the fork sag the most and be the softest.

he Type 3 spring system can be tuned for various riding styles and weight.There are four springs in the Judy
ork that can be interchanged allowing up to 32 tuning combinations. For example, aggressive riders may
want to increase their spring rate over those recommended and can do so by changing out the springs
provided in the fork with those that better meet their needs. The table below indicates rider weight and the
ecommended spring kits for those weights.Kits may be purchased through your dealer.

DJUSTMENT
A single aluminum damping cartridge in the left leg provides compression and rebound damping for the
entire fork by turning the external adjuster knob. This cartridge has a rebound/compression damping
adjustment. The compression adjustment controls the speed that the fork will collapse and covers a wide
ange. It may take several times to achieve the correct damping rates. To adjust, follow this procedure:
1. Turn the external adjuster knob clockwise to increase the damping (slower) and counterclockwise to
decrease the damping (faster). Small changes make a big difference on the trail. There are three full
turns of adjustment available from full clockwise.
QUICK TIP: Less is generally better. Lightly damped systems are more active and less harsh when riding.
IMPORTANT: DO NOT TURN ADJUSTMENT MORE THAN THREE TURNS FROM FULL CLOCKWISE.
