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|
