This is a Superior Engineering Hyperflex Hybrid Radius Arm Suitable For Toyota LandCruiser 76/78/79 Series.

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 LandCruiser 76/78/79 Series, 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.

With the arms, we 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?

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: Due to a change in the chassis width of the 2017 on 76/78/79 series these arms will not fit,
if you have a 2017 on model please refer to the image below to see if your vehicle is suitable for fitment of these arms.
