Built to original equipment form, fit and function, the Ironman 4x4 Leaf Spring Set covers Mitsubishi Triton models built from 2019 to 2021. Spring rate is approximately 48 N/mm, chosen to carry a constant load without harshness when empty. Springs are supplied as a matched pair so ride height stays even side to side. Free height gives approximately 45mm of lift over a standard, unladen vehicle. Wire is cold-wound from Spring Steel then shot peened and powder coated for corrosion resistance. Fitting raised springs may require longer brake lines, extended bump stops and a wheel alignment. Check the fitment list against your build date and VIN before ordering, as running changes were made mid-generation. This part is a common wear item on high-kilometre Australian vehicles and is worth replacing in pairs. New stock, 24 Months warranty, and dispatched from our Australian warehouse.
