What are the benefits of using King Springs for your 4WD?

The springs are the most important part of the 4WD suspension system because they provide support for the vehicle’s weight and absorb shocks from bumps in the road. The springs also help to keep the vehicle level when it goes over uneven terrain. Available at Barossa Brakes & Suspension, the King Springs suspension system is designed to provide a smooth ride for the driver. It is made up of springs, shock absorbers and other components.

King Springs – high quality, high stress spring steel

King Springs is Australia’s leading specialist manufacturer of aftermarket coil springs for world-wide automotive applications. Newer generation steel allows King Springs to reduce the amount of steel required in a spring, making it substantially lighter (by approximately 30%) and reducing the solid height therefore increasing travel. Being of particular benefit at the top levels of motorsport, this new high stress material was introduced to the leading V8 supercar teams in early 2007 giving a hugely successful endorsement of its characteristics and proven durability.

Coil springs

There are many types of springs available for 4WDs. The most common is coil springs which are made up of a series of coils that are wound around a central rod. The coils are then compressed and stretched to provide the spring’s resistance to compression and extension.

Leaf springs

Leaf springs comprise of a series of flat metal plates that have been cut into shapes resembling leaves. These plates are stacked on top of each other and attached to the vehicle’s frame or axle with bolts or rivets. Leaf springs provide more resistance than coil springs, but they also require more space in order to function properly.

King Springs height options

King Springs are designed to cross reference and give various height options on some vehicles. This information is diversified and complicated and is often conditional. Please consult your trusted suspension specialist for more information on King Springs height options.

4WD and Ford “F” Series coils

  • Front and rear standard: Raises vehicle approximately 10mm-20mm above standard.
  • Front and rear raised: Raises vehicle approximately 30mm-40mm above standard.

Note: All heights mentioned are a generalisation only. Vehicle ride heights can vary, depending on the life and/or age of vehicle, accessories fitted to the vehicle and factory options (Country Pack, S Pack etc.)

King Performance Tapered Wire / Progressive Rate Coil Springs – the “intelligent coil spring”

There is no disputing the advantage of increasing the spring rate in a vehicle to improve vehicle stability and load carrying capacity. In many 4WDs we are often confronted with three major considerations: ride comfort, shock absorber control and spring entrapment.

Progressive rate springs are the ultimate in spring design. The principle is simple. The spring rate increases when you need it (e.g. when cornering and load carrying) and decreases when you don’t. The science behind designing a progressive rate coil is knowing over what suspension travel and to what degree the spring rate will increase. This varies greatly between vehicles. Referring to the above three conditions, with King Tapered Wire / Performance Progressive Rate Springs a substantial spring rate increase is achieved with minimal loss of ride comfort as the spring rate increases and decreases where necessary. As the spring de-rates (the spring rate decreases) the shock absorber no longer struggles for rebound control and gives improved vehicle stability.

The King Springs guarantee

King Springs guarantees that all its products are manufactured with the highest quality materials and will last for the lifetime of the vehicle. These products are designed to offer maximum safety, durability, ride quality and performance. King Springs has been a leading manufacturer of truck suspension springs for over 90 years.
