Fox Quick Switch (QS) coil shocks for trail/crossover applications provide the same performance advantage Fox is known for in the backcountry now. Ride harder with less fatigue without a compromise of durability. Experience a new sense of control on the snow due to velocity and position-sensitive damping technology. Quickly adjust the compression damping with Fox's QS3 to suit snow conditions. Three positions keep the gloves on and the adjustment simple. Focus on riding instead of counting clicks. Fox's position-sensitive damping technology, Rifle Bore, is now applied to the Factory Race Series rear track shock. Spiral grooves inside the shock allow the oil to flow around the main piston, reducing the damping force in the ride zone for a plush feel. The grooves terminate through the final 30% of the travel, forcing oil to flow through the main piston. The final result is a significant increase in bottom-out resistance to cushion hard hits.
