All EFS Coil Springs are:
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 – 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 & for aesthetics
EFS Coil Springs are manufactured under a strict quality control system with the use of quality Springs steel in accordance with ISO-9002.
This ensures you are purchasing a high quality product that is backed by a 3 year/100,000km warranty.
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 accessories, increased ride height & competition.
