Superior Engineering Coil Springs… designed from the start purely for the best ride and performance available.

The design process started with on-vehicle measurements of the longest aftermarket shock for a given length, this data is then combined with the shock closed length and the suspensions actual physical limits.

Data is then combined with the highest grade of spring material offered in Australia, gives us the ability to produce the longest possible spring whilst still adhering to the required vehicle dimensions for a given lift height.

What this means is you have a longer, slightly softer more linear spring that is captive in the spring seat even when using the longest recommended shock. By having a spring that is not only captive but linear rate at full extension you have good ground pressure even when at near full flex, which dramatically adds to vehicle stability when offroad.

The other major benefit of the longer, slightly softer rate is the far superior ride quality. A short hard spring transmits forces from bumps back into the vehicle much more and doesn’t allow the shock to actually do its jobs of controlling motion of the suspension. The Superior Springs are designed around the same technology of the coilover race springs which when combined with a good shocks will provide unparalleled performance levels.

For vehicles which may carry loads at particular times we do recommended fitting Air-Bag assist.

This way both the ride and load carrying characteristics can be easily adjusted to suit any condition or load requirement.

State Of The Art Heat Treatment

Heat treatment is the most important step in the coil spring manufacturing process. Hardening and tempering is completed by an extremely precise, electronically controlled furnace to eliminate breakage and sagging.

Formed On Precision Mandrels

During forming, each coil is precisely placed, wound and monitored by a programmable hi-tech computer to achieve perfect pitch. This is especially important in manufacturing our heavy duty springs to the exact spring rates.

Precise End Configurations

Our precisely engineered coil ends are designed to fit directly into the original vehicles mounting points without modifications.

Powder Coat Finish

A durable black powdercoat finish is baked on, to provide extreme protection against the elements and to help eliminate corrosion. The smooth powdercoat surface also reduces friction when used with internal airbags.

High Intensity Shot Peening

All Superior coils are shot peened to give longer life, reducing micro cracks and increasing the springs toughness.

Fully Scragged & Load Tested

All Superior coils are scragged 100% to eliminate subsequent spring sag. The coils are also load tested to ensure they meet and maintain the required specifications. Superior also performs spring fatigue testing and spring hardness testing using state of the art testing equipment.
