The all-new IBP QS3 shocks from FOX Racing set the standard for snow bike performance. The Internal Bypass (IBP) design is position sensitive, reacting to where the shock is in the stroke. This position sensitivity delivers a smooth ride over stutter bumps and rough terrain, while maintaining bottom out resistance for bit hits and drops. The shocks feature an all-new lightweight design, which reduces critical unsprung mass and improves the overall performance of the Timbersled. The QS3 adjustment features three quick select compression settings, easily tuning the Timbersled to the riding style and conditions.
