Superlift's replacement front coil springs for the 1997-2006 Jeep Wrangler TJ.  Our engineers developed these front lift coil springs to provide the best ride quality and handling characteristics of any lift kit coil available.  They are pre-set to reduce fatigue in the steel, minimize settling and guarantee a consistent ride height.  Shot-peened to increase tensile strength and allow maximum wheel travel without sacrificing the life of the springs.
