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.

NOTE: Due to a change in the chassis width of the 2017 on 76/78/79 series We have designed these arms to work with these models.

The Performance Series radius arms are legal for use on the road once the proper engineer approval has been completed.

They are supplied with holes drilled for the sway bars, ABS lines and paperwork required for engineer approval.

Why not have extra flex as well as good on road handling?
