A coilover is an automobile suspension device. Coilover is short for coil spring over shock. It consists of a shock absorber with a coil spring encircling it. The shock absorber and spring are assembled as a unit prior to installation, and are replaced as a unit when the shock absorber has leaked. This provides damping without torsional loads.
But wait that's not all. If you look closely at the below picture you'll find a black part too that runs inside the spring. This is a shock absorber/damper which is also a part of vehicle suspension setup. In short : The coil springs help in energy absorption whilst the dampers help in energy dissipation. Had there been no dampers and only springs the vehicle would have continued to oscillate back and forth until the vibrations died out of natural damping.
