The Fox Quick Adjusting Bypass (QAB) technology allows you to manually adjust bypass tubes, quickly and easily, making fumbling with tools and visually counting turns obsolete.
The CNC Machined 6061-T6 aluminum adjustment knobs—anodized blue for compression or red for rebound–are knurled for increased grip, with laser-etched arrows indicating adjustment direction. The adjuster has the same flow and range of adjustment as our regular bypass units. The new design has a definitive click at every quarter revolution of the knob, making adjustments simple and quick—tracking shock changes is now easier than ever. The knobs also feature an O-ring seal to keep moisture and contaminants out, insuring a reliable adjustment turn after turn.
