The new FOX FLOAT 3 EVOL Quick Switch (QS) are the lightest mountain sled suspension package available. Ride harder in the backcountry with less fatigue without a compromise of durability. Experience a new sense of control on the snow due to less outboard weight. 

We designed the air-sprung mountain shocks with two primary objectives: weight reduction and ride performance. FOX optimizes the FLOAT 3 EVOL QS shocks through material reduction without a sacrifice of ride quality or structural integrity. We shaved weight from the reservoir walls and mounting hardware to save weight where it counts. The result is an air shock package in a league of its own.
