Blackhawk ULTIMATE Adjustable Upper Control Arms Nissan Navara D40 D23 NP300

Blackhawk ULTIMATE Adjustable Upper Control Arms to suit Nissan Navara D40 D23 NP300

Introducing the Revolutionary Blackhawk4x4 Adjustable Upper Control Arms.

Blackhawk4x4 has a long history of pioneering wheel alignment correction for lifted 4x4s. We've stood the test of time and continue to lead the way, with our relentless focus on design and manufacturing of industry-leading, fixed position Upper Control Arms (UCA’s).

Our latest offering results from years of tireless effort by our expert team of mechanical engineers, who have worked closely with field experts such as metallurgists, VASS Engineers, and VIC Roads signatories. Utilising state-of-the-art Computer-Aided Engineering (CAD) and Finite Element Analysis (FEA) and validating our designs through rigorous physical testing in Melbourne-based NATA testing facilities, we’ve forged a product that combines the best of technology and materials for the ULTIMATE solution.

Our range of Adjustable UCA’s pack an array of superior features that make them an invaluable addition to any 4x4. They are designed with:

• A main frame forged from 6083 aluminium for durability.
• Forged 4140 bush apertures that ensure a solid and firm fit.
• Billet machined 4140 on-vehicle adjusters that allow on-the-go customisation.
• Our unique, patent-pending, dual locking proprietary nut system for added security.
• Rubber bushings of OE spec that offer excellent vibration isolation.
• The robust and serviceable ROADSAFE high articulation, greaseable ball joint that provides a whopping 80 degrees of articulation.
• NATA certified ADR compliance for assurance of safety and reliability.
• FEA tested for ADR compliance, further reaffirming our commitment to quality and safety.

The Blackhawk4x4 ULTIMATE UCA’s provide unmatched adjustability on-car, giving OE specifications and even better for lifts from 30mm to 75mm - guaranteed, with even higher capabilities in many applications. The ball joint in the ULTIMATE UCA’s, a new design that offers 80 degrees of articulation, equals the strength of an OEM ball joint and is manufactured from high-strength 4140 chromium molybdenum (chromoly) steel.

THE ULTIMATE BALL JOINT

A proprietary ball joint providing a high degree of articulation not seen before, enabling more suspension travel.

• Provides the ability to disassemble, service or rebuild the ball joint at any time with basic hand tools.
• Unsurpassed industry leader in the design & manufacture of steering & suspension components.
• Innovative ‘on vehicle’ adjustment patented design.
• Double mechanical 4140 chromoly locking nuts ensure secure and hassle free on car adjustment.
• Additional equipment provided for ease of install and adjustment.

Only suitably qualified and accredited mechanics, with specialist 4WD Suspension knowledge should attempt fitment of these upper control arms. Ensure vehicle has a wheel alignment immediately after installation. Failure to do so may result in poor drivability and/or uneven tyre wear.

The Heavy Duty Ball joints fitted to Blackhawk 4x4 Ultimate UCA’s have been manufactured in the Hard-to-Hard style and require regular greasing, PLEASE ENSURE YOU GREASE THE BALL JOINTS PRIOR TO FITMENT & AT REGULAR SERVICE INTERVALS.

DO NOT APPLY any lubricants to the threads or surfaces of the adjuster. It is coated and designed to work with no lubricant.

Grease Nipple Notes: If a vehicle steering or suspension component is supplied/installed whereby the design includes a GREASE NIPPLE it is imperative that the joints are lubricated at relevant service intervals or when exposed to contaminants. Lack of lubrication will result in metal to metal contact, fretting, fatigue cracking and eventual failure.

Lack of lubrication restricts the ball studs in their movement due to the increased friction in the assembly from metal to metal contact, resulting in greater lateral loads on the ball stud. There are some that believe that the initial greasing of the component is enough to carry it through its lifetime. This is not the case.  It is imperative that ongoing lubrication at relevant service intervals is maintained throughout the components lifetime in the vehicle.  

This is especially relevant for 4WD components whereby contaminants might enter the boot or internal  assembly  during  offroading.  When this occurs, it is necessary to flush out the contaminants via greasing.  This will ensure that contaminants are either 'pushed' out of the housing or diluted, and will reduce the potential for excessive wear due to internal contaminants. Both lack of lubrication and internal wear due to contamination are visually identifiable on return items.

It is a regular occurrence to get return items due to lack of lubrication, incorrect lubricant used or internal contamination. These items are not covered by Warranty, so it is in your interest to ensure that all Greasable Joints are adequately lubricated upon installation, and at relevant service intervals or when exposed to contaminants. Please use a professional if you are unsure on how to correctly grease your Roadsafe product.

The Grease Nipple can be located in various locations on the steering component depending upon clearances required for greasing in-situ.
