The Problem with the standard Nissan radius arm design is that the rear pin style mounting puts a lot of load on the mushroom bushes when the arms flex down.
And this is the main cause of premature failure of the bushes.

The difference between our new design arms over the standard Nissan radius arm 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 needed 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 drivability you need and longer life from your bushes. Why not have extra flex as well as good on-road handling?

This is a Superior Engineering Superflex Hybrid Radius Arm with DropBox Suitable For Nissan Patrol GQ/GU with a 4-inch lift.

Superior Engineering SUPERFLEX Radius arms were designed in 2008 for Competition Trucks to benefit from maximum articulation as well as Excellent High-Speed Handling as well.

If you want to push the diff forward to straighten up your coils we offer the Hybrid Radius Arm Spacers.

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.

Sway Bar Bushes to suit 85mm Mounts

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.
