Blackhawk Ultimate Adjustable Upper Control Arm - Nissan Navara NP300 D23

The Blackhawk Ultimate features an innovative on-vehicle adjustment mechanism that provides approximately +/- 3 degrees of caster adjustment and fine camber tuning without removing the arm from the vehicle. This extensive range easily accommodates lift heights from 25mm to 50mm, correcting the geometry changes that cause steering wander and tyre wear on lifted Navaras. The unique design allows your suspension specialist to make precise adjustments on the hoist, test drive the vehicle, then fine-tune again without dismantling — a massive time-saver compared to traditional fixed or shim-adjusted arms. This adjustability ensures you can achieve optimal steering feel whether running a minimal lift with 32" tyres or a full 50mm lift with 33" all-terrains.

Each Blackhawk Ultimate Upper Control Arm assembly includes the complete high-tensile steel arm with integrated adjustment mechanism, premium heavy-duty ball joint with extended travel capability, greasable pivot bushings for long service life, and all necessary mounting hardware and fasteners. The arm comes with a durable powder-coated finish for corrosion resistance and includes detailed installation instructions with torque specifications. Note that this is sold as a single arm (either driver or passenger side), so you'll need to order two for a complete front end upgrade. Professional installation tools including a ball joint press and torque wrench are required but not included.

Absolutely — correcting front-end geometry with adjustable upper control arms is actually critical for safe towing performance on lifted Navara NP300s. When your vehicle is lifted without geometry correction, the altered caster angle causes steering wander and reduced self-centering, which becomes dangerous when towing heavy caravans or trailers at highway speeds. The Blackhawk Ultimate arm restores proper caster angle to factory specifications or better, dramatically improving straight-line stability and steering return when towing. Combined with appropriate weight distribution hitches and potentially rear airbags for load levelling, these arms help ensure your lifted Navara tracks confidently and predictably with caravan weights up to the vehicle's rated towing capacity of 3,500kg.

For most Navara NP300 lift applications up to 50mm, upgrading only the upper control arms is sufficient to correct geometry and restore proper steering feel, as the upper arms are primarily responsible for caster angle adjustment. The factory lower control arms typically handle articulation and load adequately at this lift height. However, if you're running extreme lift heights beyond 50mm, frequently tackle extreme off-road terrain requiring maximum articulation, or have experienced lower control arm bushing failure, then upgrading to heavy-duty lower arms as well would be beneficial. Our suspension specialists can assess your specific setup including lift height, typical usage, and accessory load to recommend whether lower arm upgrades would provide meaningful benefit for your application.

Yes, a full four-wheel laser alignment is absolutely mandatory after installing adjustable upper control arms — this is not optional and directly affects vehicle safety and tyre longevity. The entire purpose of adjustable arms is to correct caster, camber, and toe angles that have been altered by your lift kit, so professional alignment using precision equipment is essential to achieve the correct geometry. We recommend having alignment performed by a 4WD suspension specialist familiar with lifted vehicles rather than a general tyre shop, as they understand the specific requirements for modified Navaras. Plan for a follow-up alignment check after approximately 500km of driving once components have settled and bushings have seated properly under load.

While the Blackhawk Ultimate arms feature convenient on-vehicle adjustability, we strongly recommend that all adjustments be performed by a qualified suspension specialist using professional laser alignment equipment. The adjustment mechanism can be accessed while the vehicle is on a hoist, but making meaningful corrections requires precise measurement of caster and camber angles that can't be accurately assessed with DIY methods. Incorrect adjustment can result in dangerous handling characteristics, accelerated tyre wear, and potential suspension damage. The on-vehicle adjustment feature is designed to save professional workshop time by eliminating repeated removal and reinstallation, not to enable backyard adjustment. Consider the adjustment capability as a way to perfect your setup over time with your trusted suspension shop.

The Blackhawk Ultimate Upper Control Arm itself doesn't directly increase tyre clearance, but it's an essential component when running larger tyres on a lifted Navara NP300. By correcting the suspension geometry after installing a lift kit, these arms enable you to safely run the increased tyre sizes that your lift height allows — typically 32" tyres on a 30-40mm lift, or 33" tyres on a 40-50mm lift without major trimming. The improved caster angle also ensures your larger tyres track straight and don't cause wandering at speed. Maximum tyre size is ultimately determined by your total lift height, wheel offset, and any additional modifications like diff drops or body mount chops. Consult with our team about your specific lift setup and desired tyre size for personalised clearance advice.

Blackhawk4x4 backs this Ultimate Upper Control Arm with a comprehensive manufacturer warranty covering defects in materials and workmanship, giving you confidence in the quality and durability of this premium component. The warranty covers structural failures, ball joint defects, and bushing degradation under normal use conditions, though it excludes damage from accidents, improper installation, lack of maintenance, or modifications to the component. To maintain warranty coverage, professional installation is required with all torque specifications followed, regular greasing of serviceable points must be performed, and wheel alignment must be completed after fitment. Keep your proof of purchase and installation receipts, and contact us immediately if you experience any issues — we'll work with Blackhawk4x4 to resolve warranty claims quickly and fairly.

Yes, the Blackhawk Ultimate Upper Control Arm is actually designed to restore comfortable, confident daily driving characteristics to lifted Navara NP300s that have developed steering issues. Factory vehicles have geometry optimised for on-road handling, but lift kits alter these critical angles causing wandering, poor steering return, and nervous highway behaviour. By correcting caster and camber back to proper specifications, these adjustable arms return your Navara's on-road manners to near-factory feel despite the lifted height — you'll notice immediate improvement in straight-line tracking, steering weight and feedback, and overall confidence on bitumen. The sealed ball joints and quality bushings ensure smooth, quiet operation for daily commuting while still providing the strength needed for weekend off-road adventures and loaded touring across Australia.
