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.

\ \

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 the premature failure of the bushes.

\ \

The difference with 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 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?

\ \

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.\

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.

IMPORTANT NOTE:

• Superior Engineering Radius Arms now come drilled to suit 85mm sway bar saddles and ABS lines.

\ \

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.

\ \

Cast radius arms are more vulnerable to breaking, leaving your vehicle undrivable and you stranded.

\ \

In the event of a major crash or major impact Superior Engineering Radius arms may bend but will never crack and fail
