This is an optional Competition Suspension Kyosho 70mm Front Shock Spring Set. These springs feature 7 turns of 1.4mm wire, and are 4.0 rate. Manufactured using the highest quality materials available, CSI High Performance Racing Springs have been preset and shot peened for high strength, consistency and long life. Shot Peening is a method used to increase fatigue life by impacting the surface of the spring with small shot of uniform media with a force sufficient to create plastic deformation. All CSI High Performance Racing Springs are powder coated Black and are clearly marked with the free length of the spring and spring rate for quick and easy identification. They are compatible with the standard kit shocks, as well as the CSI Pro Clicker Series shocks.
