Viking's front coilover kit combines a high quality hybrid spring with a 19-position double adjustable shock. The upper coil fits the upper spring perch on your vehicle while the lower part of the coil matches the coilover shock bottom. A coil spring compressor is not required, as the adjuster acts as the compressor. The shock itself has independent compression and rebound adjusters to allow custom tuning for street, strip, auto-x and road race - all in one shock. Viking coilovers work perfectly with Tubular lower a-arm or your factory lower a-arm. head for the nearest high speed corner, 1/4 mile track or weekly cruise.
