Pull shaft down,

THEN
Push shaft up to bleed air,
insert screw snug
(do not overtighten)
Step 1. Insert the four larger o-rings into the emulsion caps and set aside. Install the small o-rings onto
the small emulsion screws by placing the o-rings on a pit mat or towel and pressing the screws into the
o-rings (add 1 small drop of oil onto the seal to help make the screw slide in easier).
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 o 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.

Shock Filling Instructions (Emulsion)
For both front and rear shocks

Step 1. Prepare caps by inserting bladders. Also at this time, install the small TKR8725 o-rings onto the TKR1248 screws.
Do not install the TKR1248 rebound screw into the shock cap during this step.
Step 2. Extend the shock shaft all the way down. Fill the shock with oil until the body is approximately 90% full.
Step 3. Slowly pump the shock shaft up and down 3-5 times to release air bubbles from underneath the piston.
Step 4. Let the shock rest vertically with the shock shaft fully extended for five minutes or until all the air bubbles have
released. After the air has escaped, top o the shock with oil (about 1-2mm below the top). If you overfill the shock, it
won’t hurt performance, it will just spill out and make a little bit of a mess.
Step 5A. Push the shock shaft into the shock body about halfway (about 1” or 25mm of the shaft exposed) to set a
base rebound. Pushing the shaft in further will decrease the base rebound and pulling the shaft out more will increase
it. Be careful to not position the shaft too far out or too far in because it will hydrolock or suck the bladder into the body
during use. Final rebound will be set in Step 6.
Step 5B. Place the cap on the shock and slowly screw down about half way. Oil will start to ooze out of the bleeder hole
on the side of the shock cap. Hold the cap and continue to fully secure it by slowly turning the shock body. The shock
will continue to bleed oil. Wipe excess oil from the shock once the cap is fully tightened down. Use TKR1115 and
TKR1116 to fully tighten your shocks. Hand tight may result in leaky shocks.
Step 6. Set your final rebound by holding the shock shaft in the desired position and installing the small rebound screw
assembly. Fully extending the shock shaft and installing the screw will produce the maximum amount of rebound. Fully
pushing the shaft into the shock body and installing the screw will produce the minimum amount of rebound. You can
now tune your rebound quickly by repeating this step.
We've found it's easiest to complete steps 1-4 on each shock before moving on to step 5.
By the time you've finished step 4 on the last shock, the first one will be ready for step 5.
