KDRR 401H
For over 30 years, we have been a trusted stockist and distributor of King Springs in Western Australia. King Springs are engineered and manufactured in Australia using advanced X5K Steel, a new generation of high-strength spring steel that is designed to withstand higher operating stresses. This material offers superior resistance to sag, enhanced toughness, and improved corrosion fatigue properties.
Upgrading to aftermarket raised springs is an excellent choice for vehicles equipped with additional accessories, heavily laden setups, or for those seeking improved load-carrying capabilities and increased ground clearance. All King Springs heavy-duty replacement springs are specifically designed to provide an uprated performance. The degree of uprating typically ranges from 20% to 40%, depending on the specific vehicle application.
When selecting the appropriate spring rate, it is essential to consider the fixed accessories on the vehicle. The approximate lift heights for various models are as follows: KDRR 401 - Light Load offers an approximate lift of 20-25mm; KDRR 401H - suitable for 100-250kg load provides an approximate lift of 40-50mm; and KDRR 401HH - designed for 100-300kg constant load also offers an approximate lift of 40-50mm.
It is recommended to pair long travel shocks with raised springs to optimize performance. Please note that the degree of height achieved may vary based on the vehicle's age, the accessories fitted, the materials used for those accessories, and certain factory options.
