Superior introduces the Hyperflex Radius Arms With Drop Boxes Nissan Patrol GQ/GU

Design Objectives & History

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 arms were great, then why not run two!, and after some testing we are now proud to offer this combination as 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 approved testing up to 110km/h, meaning the Hyperflex Radius Arms are legal* for use on road throughout Australia.

(*Nissan Patrol NON-VSC GU and GQ, Toyota Landcruiser 79 series NON-ESC – other vehicles available soon!)

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.The ultra high-clearence design allows the longer-than-standard radius arm to pivot in a specially position slot in the drop box, providing almost 15% more clearance than other styles available.

The arms and mounting drop boxes are supplied as a straight bolt in design, requiring no cutting. We also supply fitting instructions and all the bushes are pressed into the arms so you don’t have to, and all bolts need for mounting.

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?
