King Springs Buying Guide

Who are King Springs?

Who are King Springs?

If you’re in the lookout for a coil spring upgrade, look no further than King Springs. A proudly Australian brand, King Springs was established in the Gold Coast in 1956. Since then, the company has become world leaders in the design and manufacture of progressive rate springs.

Progressive rate springs feature an innovative variable design that delivers an increased spring rate when cornering or load carrying, and a decreased spring rate when it is not needed to enhance vehicle stability and rebound control. By incorporating a tapered wire design and variable pitch into the spring, King Springs deliver maximum comfort and optimal handling and load carrying capacity.

All King Springs coil springs are made from premium quality, high stress X5K spring steel. This steel is 30% lighter than traditional steel while still able to withstand a high amount of stress, making it a favourite of Australia’s leading V8 supercar teams (including Nissan, FTR and more).

Why should you replace your coil springs?

If you’re wondering whether you should replace your coil springs, the three questions to ask yourself are:

  1. Is my vehicle at the right height for what I want it to do?
  2. Is the handling up to par?
  3. Can my OEM springs maintain an acceptable height under load or while towing?

If your answer to any of these questions is no, you most likely need new springs. Whether you’re looking to replace sagging OEM springs, need more clearance for your 4x4 or simply like the look of a lowered vehicle, choose from a range of King Springs heights to suit your needs.
