Superior Hyperflex Radius Arms with Drop Boxes suit Nissan Patrol GQ/GU - Suit 3” lift

SKU: 31292



In Stock

Superior Engineering Hyperflex Hybrid Radius Arm with Drop Boxes suitable for Nissan Patrol GQ/GU with 3” inch lift.

Sold as pair.

These Superior radius arms offer extreme levels of flex for the front of your Nissan Patrol and handle extremely well on the road. Get the flex and drivability you need, and longer life from your bushes.

The difference between these Superior arms and the standard Nissan radius arm is the use of a Toyota style rear bush. This change enables increased life from the rear bush when flexing the arms up off-road by allowing the radius arm to flex down without the binding found in the pin style design.

Please note radius arms provided offer 1” inch lift more of castor correction than equivalent product listings shown on the Superior Engineering website. Feel free to contact us for more information.

Fitment Notes

  • All Superior Radius Arms for the Nissan GQ/GU models come with:
    • Pre-drilled sway bar mounting holes at 85mm centres. If you have the earlier 70mm centre sway bar saddles, we have sway bar bush and saddle options available to suit the arms.
    • Pre-drilled ABS line routing holes and ABS line clips and hardware to suit.   
  • 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 vast variances in weights and heights of vehicles and suspension combinations, Superior recommend you move your suspension in the full range of the shock absorber compression/rebound travel and consider coil bind. Also, check all areas for clearance issues.


Some vehicle modifications require LVVTA Certification. The following products may require LVVTA Certification when fitted:

  • Adjustable Drag links and Drop drag links
  • Adjustable Front Struts
  • Adjustable Panhard rods
  • Adjustable Rear lower control arms
  • Adjustable Rear upper control arms
  • Adjustable Tie rods
  • Adjustable Torque arms

  • Radius arms (in most instances)
  • Upper control arms (UCA’s)

This information is a guide only, and we recommend you contact your local certifier in all cases where certification may be required.

Product Comparison

Superior vs competitor product comparison chart
  • 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.
