This is a Superior Engineering Hyperflex Hybrid Radius Arm with Drop Boxes Suitable For Nissan Patrol GQ/GU.
Superior Engineering is leading the way again with our latest radius arms design, the Hyperflex Radius Arm.
We figured if one of our Patented Superflex was good then why not run two, and after some testing, we are now proud to offer the Hyperflex Radius Arms.
These arms don't just offer extreme levels of flex for the front of your Nissan patrol, the also handle extremely well on road.
We have completed NCOP approval testing up to 110km/h, meaning the Hyperflex Radius Arms are legal* for use on road throughout Australia.
(*currently testing has only be completed on NON-VSC Nissan Patrol GU and GQ)
The difference with our hybrid design arms over the standard Nissan radius arms is the use of a Toyota style rear bush. This change allows increased life from the rear bush when flexing the arms up off-road, by allowing the arm to flex down without the binding found in the pin style design.
With the arms, we supply the mounting drop boxes that are a straight bolt-in design requiring no cutting and all bolts need for mounting. We also supply fitting instructions and all the bushes are pressed into the arms so you don’t have to.
With these arms, you will get the flex and drivability you need, and longer life from your bushes. Why not have extra flex as well as good on-road handling?
Approved for on-road use under NCOP for GQ and GU Patrols(non-ESC) once inspected by an approved person
NOTE: To fit Sway Bar Mounts you will require 85mm sway bar mounts and bushes. If you do not have sway bar mounts or you have 75mm mounts you can purchase the required ones below. 85mm Sway Bar Mount Sway Bar Bushes to suit 85mm Mounts

Superior Engineering's HYPERFLEX ARMS are a Patented Design
Patent No's. 2008202797, 2012203220, 2012232947
Fig. 1 shows the Superior Arm deflecting only 4.1mm under load with real-world load points. Fig. 2 shows the Competitor's Arm deflecting 24.91mm under the same load points and loads, almost the same as the width of the Arm itself.
Also of note is the Competitor's Arm deflected to a point that may cause metal fatigue over time, which may lead to total failure.
NOTE: Please check ABS sensor lines(if fitted) are free to move through the full range of travel.
Factory bump stops may need to be extended depending on the coils and shock combination used.
Due to the huge variances in different weights of vehicles/heights variances and suspension combinations in
vehicles it is highly recommended to move your suspension in the full range of the
shock absorber compression/rebound travel and also taking into consideration coil bind,
check all areas for clearance issues, if you require more assistance in this talk to one of our sales team for further advice.
Below is a comparison chart showing different forms of Castor correction and how they compare in Cost, Flex, Handling and Offroad Ability.

At PPD Performance, all of our exhausts proudly feature:
Mandrel Bent Piping
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.
304 Grade Stainless Steel
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.
Bolt on installation
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.
