Aupart Drop Boxes compatible with Patrol GQ-GU are designed to allow for the radius arms to be dropped slightly below the chassis to correct the caster geometry, correct articulation of the suspension components and improve ride.

Aupart Drop Boxes are designed to suit for 3-4” lifts. Aupart offer direct Bolt-In option for the Drop Boxes. No welding or cutting required.  

The Aupart Complete Radius Arm Replacements for the GQ-GU Patrol have been designed for off-road competition use only, offering better handling on lifted vehicles and extra flex. The Aupart AX0431 & AX0432 Drop Arm kit is supplied complete with 4” Dropped Radius Arms, High Flex Rubber Bushings (factory spec dimensions) and low profile Drop Boxes. The Aupart Radius Arms are precision flame cut from massive 32mm thick solid S45C Mild Steel, and include tapped holes for ABS line & sway bar mounts (as standard). Manufactured with high tensile bush eyes, the Aupart arms feature a bushing chassis mount to offer further increased articulation and reduce the bump steer effect caused with factory style arms, resulting in improved handling at higher speeds, all finished in black E-Coating for maximum durability and rust prevention. AX0431 & AX0432 pushes the front diff forward approx. 15mm. 

When lifting IFS Vehicles, the Constant Velocity (CV) joints are put on an increased angle. This increased angle of the CV joint during operation can accelerate the wear on the joint, as well as putting additional stress on the CV boots leading to splitting and eventually premature failure of the CV. This wear is accelerated further if larger (wider) wheels and tyres are fitted.

The Aupart IFS Diff Drop Kits are application specific and supplied complete to get the job done. The bolt on kit corrects the geometry on the front driveshaft and CV’s, lowering the front diff by approx. 25mm, thus reducing the angles the CV joints need to operate on, and avoiding the expensive replacements of CV’s and boots. Allows the bash plate to be refitted. 

Aupart Upper Control Arms have been designed with ease of fitment & ongoing serviceability in mind, and are a necessity for various IFS models that have been lifted 30mm+. The Aupart arms have been designed to restore camber & caster lost on the IFS vehicles once they have been lifted, by correcting the angle of the ball joint. Without restored camber & caster settings lifted IFS vehicles will eventually show excessive tire wear and experience ride & steering issues. 

We haven't gone with a complicated ball joint or bushing setup - we have designed the ball Joint & bushing apertures to take OE spec componentry! That way if you have a ball joint or bushing issue in an out of the way area, where getting spares can be a drama, you can replace your affected part with a standard OE Spec factory or aftermarket unit.  

An absolute necessity on all raised 4WD's is the Adjustable Panhard Rod. Designed to correct axle alignment, the fitment of an Adjustable Panhard Rod eliminates potential contact between tyre and body, and improves handling issues on vehicles on vehicles lifted 2"+. All Aupart Adjustable Panhard Rods are Heavy Duty, single thread off car adjustable and come complete with bushings and steering damper mounting brackets where applicable. 

The majority of Aupart Adjustable Panhard Rods now come standard with high flex Rubber Bushings. This has been a gradual change based on customer demand. Our Aupart rubber bushings bring the factory ride feel to the upgraded replacement Adjustable Panhard Rods. The high flex Aupart rubber bushings offer less Noise, Vibration & Harshness over the polyurethane bushings for panhard applications.
