King Springs

Established over 60 years ago King Springs have paved the way in spring design and durability in all sectors of the automotive market. King Springs offer lowered, standard and raised height springs for a multitude of vehicles making them the spring of choice for Suspension Mega Store.



Industry Leader

When it comes to spring design and durability, King Springs knows neither compromise nor second best for use in any conditions, from the racetrack to the streets and the toughest outback terrains out there.

It’s exactly that mindset which is the reason why King Springs lead the way in the performance automotive spring market.

X5K Steel

All brand-new King Springs coils are produced in X5K material. This new generation steel reduces the amount of steel required in a spring, making them approx. 30% lighter. X5K also increases durability and travel by reducing the solid height.

King Springs have introduced this new high stress steel to all passenger car and 4WD designs, also providing various ride height options on selected vehicles.

Not only does X5K withstand higher operating stresses, it also has a superior resistance to sag as well as improved toughness and improved corrosion fatigue properties.

A Step in the King Springs Manufacturing Process

State-of-the-Art Manufacturing

King Springs are designed and manufactured at a purpose-built 8000 sqm factory complex on Queensland’s Gold Coast. At this modern spring factory, the company uses state-of-the-art processes to achieve maximum durability, lowest weight and maximum travel in all end-products.

The X5K coils are peeled and tampered to remove surface defects and heated to 1000 degrees in a gas furnace before being rolled. After that, they are placed into quenching oil to harden to Rockwell hardness. After hardening they are tempered, treated for maximum corrosion protection and powder coated for a durable finish.
