Built to original equipment form, fit and function, the King Springs Coil Spring covers Mazda3 models built from 2019 to 2021. Spring rate is approximately 32 N/mm, chosen to carry a constant load without harshness when empty. Wire is cold-wound from Spring Steel then shot peened and powder coated for corrosion resistance. Free height gives approximately 40mm of lift over a standard, unladen vehicle. Fitting raised springs may require longer brake lines, extended bump stops and a wheel alignment. Springs are supplied as a matched pair so ride height stays even side to side. New stock, 36 Months warranty, and dispatched from our Australian warehouse.
