32 mm socket
5 mm hex wrench
Slick Honey grease, r.s.p. Slick Kick or similar
Service and Maintenance
Use a 5 mm hex wrench to loosen the upper crown bolt.
Be sure to depressurize your Float Air Chamber first! Remove the original Float Air top cap as described in the Fox manual.
Remove both air valve caps from the AWK unit top cap. Apply Slick Honey grease, r.s.p. SlickKick or similar to the AWK top cap seal and thread.
Carefully push the AWK top cap to the beginning of the threads. Turn the unit 2-3 rev. by hand. Be careful not to strip the threads of your topcap and/or crown.
Use a torque wrench with a 32 mm socket to tighten the top cap to 24.8 Nm.
Advice: A thin piece of plastic bag between socket and AWK protects the black anodized surface. Make sure the outside edge of your socket doesn’t damage the fork crown.
Use a torque wrench with a 5 mm hex bit socket to tighten the upper crown bolt to 5 Nm.
Pressurize the AWK chamber (marked) according to the pressure chart below.
60-70 kg -> 88-108 psi
70-80 kg -> 101-119 psi
80-90 kg -> 118-132 psi
90-100 kg -> 131-148 psi
100-110 kg -> 145-158 psi
Note: Do not exceed 160 psi when main air chamber is unpressurized. This could result in damage to the AWK unit.
Pressurize the main air chamber (the unlabeled valve) according to the pressure chart below.
60-70 kg -> 40-49 psi
70-80 kg -> 46-56 psi
80-90 kg -> 53-67 psi
90-100 kg -> 62-77 psi
100-110 kg -> 71-86 psi
Note: Ensure that the AWK chamber pressure is higher than the main air chamber pressure.
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 1.7-2.2
Note: A pressure difference between AWK chamber and main air chamber greater than 160 psi is not permitted!
Do not exceed 170 psi in the AWK chamber!
Install the air valve caps on both valves.
Note: Operation without air valve caps is not allowed!
