Installation Instructions Fox 34 AWK

Please read these instructions carefully! In case of doubt do not install the AWK unit.
Improper installation may cause malfunction, resulting in serious injury or death!
Wear safety glasses and protective gloves during installation and maintenance!

Step 1

Be sure to depressurize your Solo Air Chamber first!
Unscrew the Solo Air Top Cap as described in the Fox Racing Shox manual.


Step 2

Remove both air valve caps from the AWK unit top cap.
Apply SRAM Butter, r.s.p. SlickKick or similar to the AWK top cap seal and thread.

Step 3

Lightly press the AWK unit to the beginning of the threads.
Turn the unit 2-3 rev. by hand, ensure that you don’t twist the AWK top cap.

Step 4

Use a torque wrench with a 28mm socket to tighten the top cap to 24-25 Nm.

Note: a part of a (tin) plastic bag between socket and AWK nut protect the black anodized surface. Be sure that the outer diameter of the socket fits with your forks crown – prevent damage from mounting.

Step 5

Pressurize the AWK chamber (marked) according to the pressure chart below.

60-70kg -> 80-94psi
70-80kg -> 94-107psi
80-90kg -> 107-125psi
90-100kg -> 125-140psi

Note: This is the AWK pressure presetting, not the final AWK pressure! Do not exceed 140 psi when main air chamber is unpressurized. This could result in damage to the AWK unit.

Step 6

Pressurize the main air chamber (the unlabeled valve) according to the pressure chart below.

60-70kg -> 38-44psi
70-80kg -> 44-51psi
80-90kg -> 51-57psi
90-100kg -> 57-64psi

Note: A pressure difference between AWK chamber and main air chamber greater than 140 psi is not permitted! Do not exceed 185 psi in the AWK chamber!

Fine-tuning the main air chamber pressure:
Adjust the SAG to 20-26% to identify the final main air chamber pressure.

Fine-tuning AWK air chamber pressure:
The best pressure ratio between AWK chamber and main air chamber is 1.9-2.1 for 160 mm travel, 1.95-2.2 for 150 mm travel and 2.0-2.3 for 140mm travel.

Step 7

Threads the air valve caps on both valves.

Note: operation without air valve caps is not allowed!


After 10 hours of riding check the main chamber and AWK chamber pressure.
After 150-200 hours of riding/annually visually inspect, clean/grease the AWK internal parts as described below.

Note: muddy, wet and dusty conditions can shorten the service intervals!
