Superior Engineering Dropped Radius Arms are generally used on competition trucks where maximum ground clearance is needed, although a trend is growing in Australia to fit these Radius arms into non-competition Vehicles.

\ \

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.

Benefits of Superior Drop Radius Arms

\ \

\
• Manufactured from High Tensile Plate
\
• High Tensile 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 side of Arms
\
• (Factory Sway bar will fit to allow safe on road handling)
\
• They are manufactured Suitable For various lifts
\
• Sand blasted 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

\ \

\ \

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.
