J.C. Conner’s Taos Lightening Springs are the best 4-coil kits on the market. The double torsion springs are wound from music wire and will outlast any other 4-coil kits. The spring pin is made from high tensile strength steel and won’t bend like so many others. A sturdy lock with nut and bolt are included to prevent spring loss.
