The Offroad Series of Superior Engineering Superflex Radius Arms are Suitable For Land Rover Defender 90/110/130, Discovery (Series 1) and Range Rover (Series 1) with a standard height lift.

Superior Engineering has developed the ultimate in Drop Radius Arms for Landover's.

Designed and Manufactured to take your vehicles offroad driving performance to a new level! And the visual appearance of these new Radius Arms makes a statement like no other.

Our Radius arms not only correct castor angles after performing a suspension lift, but also utilise standard OE spec Nissan Patrol rubber bushes in the Radius arms.

These features allow for increased articulation as well as better road manners and eliminate the need to use expensive Poly aftermarket bushes that are considered inferior to OE style rubber bushes.

The Superior Engineering Radius Arm design will also permit you to run a Superior Engineering Radius arm Spacer washers to push the front diff forward, increasing clearance and achieving a better approach angle.

Superior Engineering supplies all of our radius arms with the Rubber Bushes pressed in for your convenience, and you will also be supplied with genuine Nissan rear radius arm bushes and washers.

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.
