EFS Coil Springs EFS Coil Springs are produced in a variety of raised heights, from standard to 125mm & also a variety of spring rates to suit different applications - towing, load bearing, ride height & competition. * Shot Peened - To stress relieve the outer surface of the Coil, so the Coil can operate under higher fatigue & repeated load conditions to ensure longevity. * Scragged for Quality Control -This is a process where the Coil is compressed beyond its yield point; this compression will set-up residual stresses and increase the elastic limit of the spring. * Powder Coated - To resist corrosion & to protect the spring steel from minor damage. |
