King 2.5 2-Tube Piggy Back Bypass Shocks provide improved dampening and control over traditional shocks. 2.0 King Bypass Shocks reduce harshness by adding two external bypass tubes which allow free-flow around the piston. The King 2.5 2-Tube Bypass Shocks feature one compression tube and one rebound tube for control in both directions. The 2.5 King Piggyback Bypass Shocks provide a nice clean package for easier mounting than other reservoir configurations. Upgrade to pre-tuned King 2.5 Bypass Shocks from AccuTune Off-Road today.
