King 3.0 2-Tube Piggy Back Bypass Shocks provide improved dampening and control over traditional shocks. 3.0 King Bypass Shocks reduce harshness by adding two external bypass tubes which allow free-flow around the piston. The King 3.0 2-Tube Bypass Shocks feature one compression tube and one rebound tube for control in both directions. The 3.0 King Piggyback Bypass Shocks provide a nice package for easier mounting than other reservoir configurations. Upgrade to pre-tuned King 3.o Bypass Shocks from AccuTune Off-Road today.
