EFS Coil Springs are manufactured under a struck quality control system with the use of quality spring 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, ride height & competition.
Key features include:
- 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 & for aesthetics.
Vehicle FitmentEFS coil springs are available for most 4x4 and off road vehicles.
