Fox 4.0 4 & 5-Tube Piggyback Bypass Shocks provide improved dampening and control over traditional shocks. 4.0 Fox Bypass Shocks reduce harshness by adding four or five external bypass tubes which allow free-flow around the piston. The Fox 4.0 4-Tube Bypass Shocks feature two compression tubes and two rebound tubes for control in both directions and a smoother transition into the bump and top-out zones. Fox 5-Tube Bypass Shocks feature an additional compression tube to offer more adjustment. The 4.0 Fox Piggyback Bypass Shocks provide a nice package for easy mounting. Upgrade to pre-tuned Fox 4.0 Bypass Shocks from AccuTune Off-Road today.
