Blackhawk Upper Control Arms for Isuzu D-MAX RG, MU-X RJ and Mazda BT-50 TF
Improve lifted suspension geometry with Blackhawk Upper Control Arms UCA4727D. Designed for the Isuzu D-MAX RG, Isuzu MU-X RJ and Mazda BT-50 TF, these arms provide fixed caster and camber correction for 30–70mm suspension lifts, helping restore steering response and suitable wheel alignment.
Features
- Built-in alignment correction: Blackhawk's fitting guide specifies a 2-degree caster increase and 0.75-degree increase in negative camber. Final alignment is set using the factory adjusters.
- Improved clearance: Revised geometry helps reduce interference with suspension components and larger wheel and tyre combinations.
- Fixed ball-joint position: Reoriented housings help reduce binding during suspension droop while retaining consistent correction geometry.
- Serviceable ball joints: Heavy-duty greaseable ROADSAFE joints use heat-treated ball studs and seating surfaces to resist wear.
- Vibration isolation: OE-specification rubber bushes help absorb noise, vibration and harshness.
- Protective finish: Black e-coating provides a durable finish.
- ABS lead mounting: Mounting provisions allow the factory ABS leads to be secured to the replacement arms.
The Blackhawk design undergoes finite element analysis and review by VASS engineers. Replacement ball joints and bushes are available for ongoing servicing.

Frequently Asked Questions
Are these adjustable upper control arms?
UCA4727D uses fixed correction geometry and fixed ball-joint positions. The vehicle's factory adjustment points are used to complete the wheel alignment.
Is a wheel alignment required after fitting?
Yes. Have the arms installed by a qualified mechanic with specialist 4WD suspension knowledge, followed by a professional wheel alignment.
Do the ball joints need greasing?
Yes. Grease the joints before installation, rotating and articulating the ball stud to distribute grease throughout the joint. Follow Blackhawk's servicing instructions for ongoing maintenance.
