This is a Superior Engineering Hyperflex Hybrid Radius Arm Suitable For Toyota Landcruiser 80/105 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 80/105 Series, the also handle extremely well on road.
We will be completing the NCOP approval testing up to 110km/h soon, meaning the Hyperflex Radius Arms will be legal* for use on road throughout Australia.

NOTE: Testing has not yet been completed but as soon as it is approved the Superior Hyperflex Radius Arms sold previously will be legal on road.

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.


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
