The Problem with the standard Nissan radius arm design is that the rear pin style mounting puts a lot of load on the mushroom bushes when the arms flex down.

And this is the main cause of premature failure of the bushes.

The difference between our new design arms over the standard Nissan radius arm is the use of a Toyota-style rear bush.

This change allows increased life from the rear bush when flexing the arms up off-road, by allowing the arm to flex down without the binding found in the pin-style design.

With the arms, we supply the mounting drop boxes that are a straight bolt-in design requiring no cutting and all bolts needed for mounting.

We also supply fitting instructions and all the bushes are pressed into the arms so you don’t have to.

With these arms, you will get the drivability you need and longer life from your bushes. Why not have extra flex as well as good on-road handling?

If you want to push the diff forward to straighten up your coils we offer the Hybrid Radius Arm Spacers.

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.

85mm Sway Bar Mount
Sway Bar Bushes to suit 85mm Mounts

• Manufactured from High Tensile Bisalloy 80/Strenx700 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
• Factory Sway bar will fit to allow safe on-road handling (see important note)
• Factory ABS lines will bolt-on. (See important note)
• RADIUS ARMS are manufactured Suitable For various lifts
• Sandblasted with rust prevention applied
• Powder Coated for maximum durability and finish
• High Tensile Bisalloy 80/Strenx700 Plate will not crack unlike Cast Radius Arms(see image below for example)
• Sway Bar Adapter plate bracket and bolts have a SA5 Zinc coating for rust prevention
• Allows vehicle to track correctly on road due to correct caster
• Maximum Clearance between the Tie Rod and the Radius Arms
• Factory bushes fit the RADIUS ARMS; we don’t use special sizes Bushes

IMPORTANT NOTE:
Superior Engineering Radius Arms now come drilled to suit 85mm sway bar saddles and ABS lines. NOTE: Please check ABS sensor lines(if fitted) are free to move through the full range of travel. 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.

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
