We disconnected the stock coilover by removing the three nuts securing the upper coil seat to the frame perch. Do not loosen or remove the larger center nut securing the spring seat to the shock shaft. This can result in the stock coil assembly coming apart violently, causing damage to components and possible injury. With the top loose, we removed the bolt holding the lower shock eye to the lower control arm. Remember the bolt orientation, as this bolt will be reused.
