Blackhawk4x4 ULTIMATE Adjustable Upper Control Arms – Precision Redefined

At Blackhawk4x4, we've long been at the forefront of wheel alignment solutions for lifted 4x4 vehicles. With a legacy built on innovation, our fixed-position Upper Control Arms (UCAs) have become the gold standard in the industry.

Now, we're raising the bar again.

Introducing the Blackhawk4x4 ULTIMATE Adjustable UCAs — the first-ever street-legal, on-car adjustable, forged Upper Control Arms. Engineered for precision, strength, and flexibility, these UCAs are designed for serious 4WD enthusiasts who demand the ultimate in performance and adjustability.

Why Adjustable? Why Now?

We listened to the 4x4 community and recognized the growing demand for more customization in suspension geometry. Our team of expert mechanical engineers worked alongside metallurgists, VASS engineers, and VIC Roads signatories to deliver a solution that meets both real-world demands and rigorous regulatory standards.

Leveraging cutting-edge CAD design, Finite Element Analysis (FEA), and NATA-certified physical testing, we’ve crafted a product that delivers unmatched reliability, performance, and compliance.

Key Features of the ULTIMATE Adjustable UCAs:

• Forged 6083 Aluminium Main Frame – Lightweight yet incredibly strong for extreme durability.

• 4140 Chromoly Bush Apertures – Forged for a tight, robust fit.

• Billet Machined On-Vehicle Adjusters – Make precise alignment changes quickly and easily without removing the arms.

• Proprietary Dual Locking Nut System – Patent-pending design for maximum adjustment security.

• OE-Spec Rubber Bushings – Deliver excellent vibration isolation and ride comfort.

• ROADSAFE High-Articulation, Greaseable Ball Joint – Serviceable and rated for an impressive 80 degrees of articulation, using ultra-strong 4140 chromoly.

• NATA-Certified ADR Compliance – Meets Australian safety and regulatory standards.

• FEA-Tested and Field-Validated – Proven to withstand the toughest conditions and ensure top performance.

• The Blackhawk4x4 ULTIMATE UCAs are engineered to restore or improve OE geometry on lifted vehicles from 30mm to 75mm, and often beyond. The newly designed ball joint rivals OEM strength and articulation while providing the added adjustability needed for optimized alignment and tire wear — especially critical in lifted setups.

  And for peace of mind, our comprehensive fitting instructions are available online, guiding users through proper installation and adjustment tailored to their lift and alignment needs.

• Built by 4WDers, for 4WDers
