All Ironman coil springs are designed to provide a safe, comfortable ride while also providing additional ground clearance. station 4×4 coil springs are CNC cold wound and bar peeled for maximum reliability and consistency, every coil spring is ‘shot-blasted’ to ensure long life, preset to its solid height, and load tested to avoid spring sag. All springs are electro-static powder-coated for a gleaming appearance. Available in raised height and perfectly matched to Ironman 4×4 Shock Absorbers.
