Superior Engineering new coils, 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, which 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 the 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 the motion of the suspension.
The Superior Springs are designed around the same technology as the Coilover race springs which when combined with good shocks will provide unparalleled performance levels.
For vehicles that may carry loads at particular times, we do recommend fitting Air-Bag assist.
This way both the ride and load carrying characteristics can be easily adjusted to suit any condition or load requirement.
Sold as a pair.
Superior Engineering offer custom built suspension solutions, with unique adjustability and performance.
These kits are assembled to order to suit your requirements, with an average lead time that can vary between 1-3 weeks.
If you need a specific eta, please contact us before ordering and we will be sure to assist you.
Consolidated freight allows PPD Performance to combine multiple orders onto a single pallet and transfer them together, reducing freight costs by sharing them across orders.
This option adds an additional 1–3 week delay on top of the standard 1–3 week supplier lead time.
If you require your item sooner, please contact us before or after ordering to discuss specific lead times or faster freight options.
PPD Performance exhausts comprise of mandrel bent, stainless pipe work, delivering uncompromising flow, performance, and sound. Mandrel bending involves placing a mandrel inside the piping, before it is bent to shape. In comparison; cheaper press bending from other manufacturers squashes the tube as it is bent, reducing flow.
Tired of your mild steel exhaust systems rusting out after a year or less? Time to shop for a stainless steel system? There’s still some things you need to be aware of. Our competitors typically advertise their exhaust products as stainless steel. Most don't stipulate the differences between ferretic 409 grade stainless steel and austenitic 304 stainless steel.
Significant differences exist between the metals that make one better for performance exhaust applications than the other. Let us explain
The corrosion resistance of your 4x4 exhaust depends on the content of chromium and nickel found in the alloy. 409 grade stainless steel is used by many manufactures due to its medium strength, formability and very low cost. Typically, 409 grade stainless steel has a chromium content of between 10.50% - 11.75% and a nickel content of less 0.50%.
Why do we use 304 grade stainless steel piping for 4x4 performance exhausts? Because it is more resistant to rusting than ferretic based stainless steels such as 409. However, because of its low ferrous content, 304 can develop a golden colour when exposed to high heat over time. In fact, the ferrous metal content is so low that magnets won’t stick to it, making the identification of 409 and 304 grade stainless steel very easy.
Put simply, 304 grade stainless is the best value material used in the 4x4 exhaust game when strength, corrosion resistance and performance are at the top of your list of priorities.
Type 304 steel is engineered with chromium and nickel content and proves to be resistant to oxidation, corrosion, and durability.
Together with a polished finish - it is a great choice for your 4x4 offering excellent corrosion resistance from exhaust emissions, moisture and beach exposure.
All PPD Performance exhausts are designed to follow the same orientation and layout as the factory exhaust, making for easy bolt on installations. Our systems utilise the standard hanger locations, which means you don't have to use anything other than the factory rubbers.
