Standard Fox Float air shocks can be very progressive and have a limited range of adjustment. Air pressure can be set low for a plush ride, but this can cause increased sag, instability, chassis roll, front end push and excessive bottoming. A higher air pressure increases bottoming resistance and vehicle stability, but the ride may become harsh and suspension travel is reduced due to the increased spring rate.

dualpressreservoirs

Dual Pressure reservoirs are infinitely adjustable and have two charging valves so ride height and bottoming resistance can be adjusted independent of one another. The additional air volume makes the shock more linear, so higher air pressure can be used for sharp handling, good stability, and reduced body roll, while not sacrificing bottoming resistance or ride quality. Additional bottoming resistance and progression can be added if desired by simply changing the pressure in the bottoming chamber.
Dual Pressure reservoirs can be installed with basic hand tools. Each kit includes all necessary hardware, including billet aluminum mounting clamps and air fittings. The reservoirs can be installed on all Fox Float and Float 2 air shocks for snowmobiles, including Yamaha, Arctic Cat and aftermarket applications. A complete Dual Pressure kit for a pair of front shocks is $289.99. Rear shock kits start at $164.99, from Hygear Suspension in Lansing, New York.
