The advantages of coilover kits include increased wheel travel, optimized shock damping and the ability to customize spring rates to suit your specific needs. Foxs threaded shock bodies make it easy to fine tune ride height for even more customization. Dual coil springs result in a progressive spring rate that is comfortable on the street and over small bumps on the trail while still providing stability and control over large obstacles. Remote reservoirs increase fluid capacity for cool, consistent shock damping. Rubicon express coilover mounts are made in the usa from plate steel to maximize clearance.
