How to Adjust Front Fox Racing Shocks for Snowmobiles

Picking the best shocks for your snowmobile or other extreme sports machine can make the difference between a bumpy, uncomfortable ride and a smooth glide across the pond or track. Purchasing a set of Fox Racing Airshox can lead to a comfortable ride, but to yield the full potential of this quality upgrade, you must adjust the shocks properly. Learning how to complete this easy task can help you optimize your riding style and rip through whatever terrain you travel.

Instructions

    • 1

      Choose an outdoor location for adjusting your Fox Racing Airshox. Remember that air changes density in different temperatures. The density can vary up to 10 pounds per square inch, so make your adjustments in the same type of temperature in which you ride.

      Remove the cover cap by hand from the EVOL air chamber #1 pump, which came with your Fox Racing Airshox kit. Removing the cap gives you access to the shock's Schrader valve, which is similar to a valve on a car or bike tire. Thread the pump on to the Schrader valve. If the pump shows a reading, you have connected it to the Schrader valve correctly. If the shock is empty, give it a few pumps, and the pressure should slowly increase. If the reading increases quickly within a few pumps, you have threaded the pump incorrectly.

      Pump the shock up to the desired pressure level. The rider's weight, the riding style and the weather all play factors when deciding how much air to pump into the shock. Typically, you want the pressure to be between 100 to 200 psi. Never pump the air chamber pump to more than 300 psi. Start by bringing the level up to 200 psi, and then let out some air by pushing down on the black bleed valve on the pump. Repeat on the other shock, and then replace the cover cap on the pump.

      Place your jack under the jack point for your snowmobile, and raise it so the skis are a few inches off the ground. This will fully extend your suspension and ensure a proper adjustment.

      Remove the main air chamber cap on the shock's main air chamber, and thread the Fox Airshox kit's main air chamber #2 pump on to the Schrader valve in the same way you did for the EVOL pump.

    • 6

      Pump up the main air chamber. You typically want the pressure to sit between 20 and 100 psi. Never put more than 150 psi into the chamber.

      Remove the pump, and replace the main air chamber cap.
