KJRR 50

With over 30 years of experience, we are proud to be a leading 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 endure higher operating stresses. This material offers superior resistance to sagging, enhanced toughness, and improved corrosion fatigue properties, making it an excellent choice for performance and durability.

Upgrading to aftermarket raised springs is particularly beneficial for vehicles equipped with additional accessories, those that are heavily laden, 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 installed on the vehicle. For example, the approximate lift height can be categorized as follows: 30-40mm for KJRR 50, which is suitable for light loads, and KJRR 50HD, which is designed for constant loads ranging from 300-500kg.

It is recommended to pair long travel shocks with raised springs to optimize performance. Please note that the actual degree of height increase may vary based on the vehicle's age, the accessories fitted, the materials used for those accessories, and certain factory options.
