This is a Superior Engineering Hyperflex Hybrid Radius Arm with Drop Boxes Suitable For Nissan Patrol GQ/GU.

Lifetime Warranty

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

Patent No's. 2010100451, 2011904187

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.
