Fox has provided some Q & A to common service questions they get regarding their innovative FLOAT Airshox. Now that these lightweight shocks are being offered on more and more sleds right from the factory, we thought it would be helpful to share this tech information about the shocks to help you better understand what is normal and what to be looking for. Like all high-pressure gas shocks, the FLOATs will require disassembly and servicing to maintain their performance characteristics.

First, you should monitor the air pressure at least once every other month and you should perform air sleeve maintenance once a year. Also, they should have a complete rebuild and oil change every 3,000 to 5,000 miles. Complete service should only be performed by a trained technician as it requires specialized tools and knowledge, just like traditional FOX shocks.

Question: There is a slight amount of oil at the air sleeve/body cap joint. Is there something wrong?
Answer: No, the air sleeve threads are lubricated with light grease to make disassembly easier. Sometimes, a slight amount will ooze down the air sleeve. Simply clean the air sleeve and body cap. Keep an eye on the air spring pressure to make sure it remains steady.

Question: Is it normal for oily dirt to build up at the FOX Samurai wiper?
Answer: Yes, this means that the wiper system is working properly. Periodically wipe the oily dirt from the Samurai wiper to keep it clean.

Question: There are small dings on my aluminum impact body. Will this cause an air leak?
Answer: No, the air seal occurs on the inside of the air sleeve only. Small dings on the impact body over time are normal and are nothing to be concerned about. However, big scratches or dings in the impact body will allow water and dirt contamination into the air sleeve that could lead to a long-term air seal failure. In the case of major scratches or dings in the impact body, it is best to replace it.

Question: Will I have to adjust my air pressure when I go up in altitude?
Answer: No, the air pressure in the air sleeve is not affected by changes in altitude

Question: What about the damping in this shock?
Answer: This shock uses the same proven velocity sensitive, oil damped valving arrangement that is used in all FOX Racing Shox shock absorbers. The valve code or calibration has been carefully tuned for each application to give the best all-around performance over a variety of conditions.

Question: The air pressure in my shock absorber is different every time I measure it. What’s wrong?
Answer: First be sure that the suspension and shock absorber is fully extended by jacking up the vehicle by the frame so that the skis are completely unloaded and have no weight on them. This is the “home” position for measuring pressure. Second, every time you thread on the pump to the shock, the pressure reading will go down slightly as the gauge fills up. This is typically between 2 and 5 psi.

Question: My shock absorber leaks air slowly over time. What’s wrong?
Answer: There are three possible leak paths. To determine which one is the culprit, remove shock from vehicle, charge the air spring pressure, and submerge the shock in a sink or a bathtub. If the air bubbles are coming from the air filler valve, replace it (FOX part number #802-00-001-A). If the air bubbles are coming from the body cap/air sleeve joint, replace the body cap O-ring (part number #029-01-135-A). If the air bubbles are coming from the bottom of the air sleeve past the FOX Samurai wiper, clean the air sleeve and replace the air piston seal (part number #036-01-014-A) and the two Air Piston Slyde Rings (part number #002-00-012-A).
