Our King 2.5 Performance kit for the Chevrolet Colorado ZR2's takes our suspension to the next level. We utilize our Camburg 1.25" heim/uniball upper arms and combine them with KING’s 2.5 series front and rear shocks with compression adjusters. This combination of parts not only improves the ride and handling on-road but more so off-road with the larger diameter shocks and external reservoirs. With the upper arms these shocks increase wheel travel do to the extended travel version coilovers.
