SINGLE ARM ONLY

If you have don't need any castor correction and still want the flex afforded by the Superior Super Flex arms, then here is your solution.

Run one of our superflex arms on the Passanger side and your standard radius arm on the driver side, and you will receive all the benefits of the superflex arms at half the cost.

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.

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.

Since their introduction to the Australian and overseas market there has been a huge trend towards choosing Superior Engineering SUPERFLEX Arms over the standard Radius Arm design.

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
