Shock Filling Instructions

For both front and rear shocks

Step 1.

Start by inserting the four larger o-rings into the emulsion caps and set

aside. Next install the small o-rings onto the small emulsion screws.

Step 2.

Fill shock with oil all the way to the top and pump the shock shaft up and down 3-5 times.

Step 3.

Screw on the cap all the way tight (shock tool TKR1115 is helpful for holding the shock body).

Be careful to not cross-thread the caps. Start by turning in the oposite direction before tightening.

Step 4.

With the shock at about a 45° angle, push and hold the shock shaft to the top of the stroke and

insert the prepared emulsion screw/seal. Oil should leak out during this process. If it does not, add more oil.

Tighten the screw until snug (do not over-tighten). Wipe off excess oil before moving on to step 5.

Step 5.

Pump the shock shaft up and down about 20 times vigorously. This emulsifies the oil.

Step 6.

With the shock shaft fully extended, remove the emulsion screw from the cap to do the final bleed.

Step 7.

With the shock at about a 45° angle, push and hold the shock shaft to the top and insert the

prepared emulsion screw/seal again. Oil will leak out during this process. Finish by tightening the screw

until snug (do not over-tighten).

We've found it's easiest to complete steps 1 & 2 on each shock before moving on to step 3.

By the time you've finished step 2 on the last shock, the first one will be ready for step 3.

Note: Kit shock oil is suited for ~75°F (~24°C). If ambient temperature changes more than ~10°F (~5°C), adjust oil to suit.
