Wholesale EFS Coil Springs Rear (Grand Cherokee 99-06)

Description

EFS Coil Springs are manufactured under a strict 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.

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 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.
