The Blackhawk upper control arm kit (manufacturer part UCA4727CV2) suits the Holden Colorado RG (2012-2016), Holden Colorado 7 (2012-2016), Isuzu D-Max (2012-2019) and Isuzu MU-X (2013-2019), restoring correct camber and caster on vehicles running a 2" to 3" lift. Each arm ships with heavy-duty Roadsafe ball joints pre-fitted and OE-style rubber bushes, extending service life over the factory pressed-steel arm. Holden Colorado RG 2017-on facelift models take the UCA4670C kit instead. Pair these arms with your lift kit to remove excess CV and ball joint angles. In stock in Australia with manufacturer warranty and fitment support from our team.

This UCA kit doesn't include springs, but correct control arm geometry only pays off if your spring rate suits the load on the front end. Choose a spring rate based on constant accessory weight such as a steel bullbar, winch, driving lights and bash plates rather than occasional payload. Talk to us before ordering coil springs alongside this arm so the finished geometry and ride height land where you expect.
Fitment is a bolt-in job for an experienced DIY installer with a hoist and ball joint press, or your regular 4WD workshop. Wheel alignment is mandatory straight after fitting — camber and caster settings change the moment the new arm goes in. Allow a 500km bed-in period for the rubber bushes to settle before a final alignment check. If you're also running new front springs or a lift kit, fit both together so the geometry is set once, not twice.
Blackhawk4x4 builds suspension components for Australian conditions, from corrugated outback tracks to daily commuting with a loaded tray. This upper control arm is specified with Roadsafe ball joints, a componentry brand well known in the Australian 4WD parts trade, rather than an unbranded joint of unknown origin. Backed by manufacturer warranty, you can view the full Blackhawk4x4 range to match shocks and springs to this arm.
This kit suits D-Max, MU-X and Colorado owners running a 2" to 3" lift who need the geometry corrected properly rather than left on factory arms designed for standard ride height. It's a common fit for tradespeople running a canopy and tools, and tourers towing a camper or caravan. If you're carrying constant rear payload as well, look at airbag suspension to support the load without over-stiffening the ride.

Yes, this Blackhawk upper control arm kit is built for the Isuzu D-Max RG (2012-2020), MU-X UC (2013-2020) and Holden Colorado RG (2012-2020). It bolts directly to the factory upper mounting points on these models with no cutting or drilling. If your vehicle sits outside these year ranges, contact our team before ordering to confirm the arm matches your chassis.
This kit doesn't add lift on its own — it's designed to correct camber and caster once your vehicle is already raised, typically with a 2" or 3" lift kit fitted. The extended arm geometry gives the ball joint and CV shaft the range of motion a lifted front end needs. If you haven't lifted the vehicle yet, pair this arm with a suspension lift kit for the intended result.
You get two Blackhawk heavy-duty upper control arms, one for each side, with Roadsafe ball joints and OE-style rubber bushes already fitted. Mounting hardware is included for a direct bolt-in installation. Lower control arms, shocks and coil springs are sold separately.
Yes, correcting camber and caster with this arm helps keep tyre contact patch even when the front end is loaded with a bullbar and winch, which is common on tow rigs. The arm itself doesn't change load capacity, so pair it with the right front coil spring rate for your accessory weight. Talk to us about matching springs if you're towing regularly.
If your D-Max, MU-X or Colorado is running a 2" or 3" lift on the factory upper arm, yes — this is exactly the upgrade that fixes the geometry issue. Factory arms are only designed for standard ride height, so a lifted vehicle on factory arms often shows excess negative camber and reduced ball joint life. This Blackhawk arm extends the working range so the joint sits in its intended angle.
Yes, a wheel alignment is mandatory immediately after installing this control arm. Camber and caster change as soon as the new arm geometry replaces the factory unit. We recommend a follow-up alignment check after a 500km bed-in period once the rubber bushes have settled.
This control arm kit doesn't include springs, so spring rate is selected separately based on your constant accessory load. If you're adding a bullbar, winch or bar work, choose a heavier front coil spring rate to suit. Our team can help match spring rate to this arm and your intended lift height.
Correcting camber and caster with this arm can improve clearance consistency at the guard when running larger tyres on a lifted D-Max, MU-X or Colorado, but tyre size clearance depends on your lift height, wheel offset and tyre width, not the control arm alone. Check your specific lift kit's tyre fitment notes or contact us with your intended tyre size before ordering.
This Blackhawk upper control arm is covered by manufacturer warranty against defects in material and workmanship. The Roadsafe ball joints fitted to the arm carry their own componentry warranty as well. Keep your invoice as proof of purchase for any warranty claim, and contact our team if you have any fitment or product concerns.
Yes, the OE-style rubber bushes used in this arm are chosen to keep road noise and vibration close to factory levels, unlike solid poly bush setups. Combined with a correctly aligned front end, the ride stays predictable for daily commuting as well as towing and touring. Many D-Max, MU-X and Colorado owners run this arm as their everyday driver after a lift kit install.
