NOTE: To fit Sway Bar Mounts you will require 85mm sway bar mounts and bushes.
\ If you do not have sway bar mounts or you have 75mm mounts you can purchase the required ones below.\

Benefits of Superior Drop Radius Arms

\ \

\ \

\
• Manufactured from High Tensile Plate
\
• High Tensile Bar Bush Eyes
\
• Massive 32mm main Beam thickness for maximum strength
\
• Rubber Bushes pre-fitted into arms
\
• Laser-cut to precise measurement and caster location
\
• Authentic Superior Engineering Logo machined into the side of Arms
\
• They are manufactured Suitable For various lifts
\
• Sandblasted with rust prevention applied
\
• Powder Coated for maximum durability and finish
\
• High Tensile Plate will not crack unlike Cast Radius Arms
\
• Allows vehicle to track correctly on road due to correct caster

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

Below is a video of Nissan Patrol GU passing an LT2 Lane Change Test with ease, this test shows the Patrol passing the test loaded to GVM at 110km/h.
\ Proof that Superior Engineering Superflex and Radius Arms can still handle when on-road as well as the added flex off-road.

\ \

​Note: Factory bump stops may need to be extended depending on the coils and shock combination used.
\ Due to the huge variances in different weights of vehicles/heights variances and suspension combinations in
\ vehicles it is highly recommended to move your suspension in the full range of the
\ shock absorber compression/rebound travel and also taking into consideration coil bind,
\ check all areas for clearance issues, if you require more assistance in this talk to one of our sales team for further advice
