Tough Dog Shock Absorbers

Sydney, New South Wales, Australia, July 2011

Australia's 4WD Action magazine featured a 19-page torture and comparison test of the 10 best-selling 4WD shocks in Australia..

Tough Dog fought off the competition and were awarded 1st place, in a line-up that included serious competitors such as Koni, Bilstein, Old Man Emu, Raw, TJM amongst others.

  • Real-world testing was conducted by Australian off-road racing legend Bruce Garland.

    Here's what Bruce had to say about the Tough Dogs:

"From the moment we drove out of the fitting bay, I knew there something impressive underneath the Cruiser. They gave the Cruiser almost unmatched pitch balance front to rear that controlled the vehicle superbly where other shocks were simply unsettled.. They were able to soak up the uneven ground with ease without ever letting the vehicle skip across the track.. They gave a satisfying amount of confidence to the driver and always stayed predictable even across the roughest sections of track.. The balance of comfort inside the vehicle and driver control was ideal.. Soft enough to soak up the rough stuff, while remaining stiff enough to give you plenty of confidence behind the wheel".

King Springs suspension

King Springs was established in 1956 in Australia in Queensland's Gold Coast. King Springs leads the way in the design and manufacture of advanced progressive springs with both variable pitch and tapered wire forms.

Today, King Springs is Australia's leading specialist manufacturer of aftermarket coil springs for world-wide, automotive applications.

King Springs service all sectors of the automotive market (4x4 and also passenger and commercial vehicles) and also in various Motorsport categories including circuit, rally, speedway and off-road racing.

The strength of the King Spring's reputation lies in the quality of steel used and their special in-house methods of production. King Springs is a genuine specialist in the field of variable pitch rate coils. All King Springs are manufactured from the new X5K high stress steel for optimum performance.This new generation steel allows King Springs to further improve many of their existing designs by reducing the amount of steel required in a spring, making it substantially lighter (by approximately 30%) and reducing the solid height therefore increasing travel.

The Australian company King Springs is one of the world's rare performance coil spring specialists (OE heigh application or lift) to ensure both quality production and a policy of continuous improvement to meet market demands.

An almost absolute reference in coil springs, King Springs distributes tough and long lasting products around the world for 4X4s & SUVs.

Euro4x4parts is now the exclusive distributor of King Springs in EUROPE.

The wide range offered by King Springs means you can choose the very best solution for setting up your vehicle.

Whether it's overland, competition, green laning or pro use (or why not a mixture of them all !) EURO4X4PARTS offers you different combinations that allow you to combine suspension lift with load capacity to match your requirements.

Height

  • standard to replace the original spec springs.
  • from +4 to + 17.5 cm above standard height (shock absorbers need to be changed to match). 

Load capacity

  •  medium: similar flexibility to the original coil springs.
  •  from HD (Heavy Duty, 200 kg) to EHHD (Extra Heavy Heavy Duty, + 800 kg) (for springs that are HD or above, the permanent load must match the load capacity to ensure optimum comfort).

Strength and durability

A careful choice of steel offers both lighter weight coils and improved durability.

Certification

No problem! KING SPRINGS products are certified ISO9001: 2008.
