Blackhawk's upper control arm kit is purpose-built for the Holden Colorado RG facelift (2017-on), restoring correct caster angle and ball joint geometry once a lift kit is fitted. Supplied as a pair with heavy-duty greasable ball joints and reinforced mounting points, this upper control arm upgrade reduces CV joint strain and cuts the uneven tyre wear that comes with a raised ride height. It's the direct companion piece for Colorados running 2" to 3" lift kits, correcting geometry that stock arms can't handle at height. In stock in Australia now, backed by a manufacturer warranty and fitment support from our team.

This kit is a control arm upgrade, not a spring, but the geometry correction it provides matters more the heavier your front-end load. If you're running a bull bar, winch or bash plates, correct caster from this upper control arm keeps steering feel consistent even with those constant loads. Talk to us about matching front coil rate to your accessory weight when you order your lift kit alongside this arm.
Fitment is a bolt-in job for an experienced 4WD workshop or a confident DIY installer with basic hand tools and a hoist. Wheel alignment is mandatory after fitting — caster, camber and toe all shift when the upper control arm geometry changes. Allow a 500km settling period for bushes to bed in before a final alignment check. Pair this kit with a set of upgraded control arms and matched shocks for a properly corrected lifted front end.
Blackhawk4x4 builds suspension components specifically for common Australian utes and wagons, with parts developed against the loads and lift heights local 4WDers actually run. This upper control arm carries a manufacturer warranty and is dispatched from Australian stock, backed by our team's fitment advice for your specific Colorado build. View the full Blackhawk4x4 range to match this arm with the right lift kit and shocks.
This kit suits Colorado owners who've already fitted, or are about to fit, a 2" to 3" lift kit and need the geometry corrected properly rather than left on factory-spec arms. It's a common upgrade for tradespeople running heavier front-end accessories and tourers covering long distances where tyre wear and steering feel matter. Load-carrying setups running airbag suspension at the rear often pair this front-end correction for a balanced ride overall.

This Blackhawk upper control arm kit is built specifically for the Holden Colorado RG facelift, model years 2017-on. It won't fit pre-facelift Colorados from 2012-2016 due to differences in the front-end mounting points. Check your build date or use our parts finder for the Colorado if you're unsure which series you have. Our team can confirm fitment against your VIN before you order.
This kit doesn't add lift height on its own — it's a geometry-correction part designed to work alongside your lift kit. It's built to suit Colorados running a 2" to 3" lift, correcting the caster angle that goes out of spec once the vehicle is raised. If you haven't fitted a lift kit yet, pair this with coil springs and shocks sized for your target height. Fitting this arm without a lift kit isn't necessary, as factory arms handle unmodified ride height correctly.
You get a pair of Blackhawk upper control arms with heavy-duty greasable ball joints already fitted, reinforced pivot bushes, and all mounting hardware needed for installation. Grease nipples are included for ongoing maintenance of the ball joints. Shocks, coil springs and steering dampers are sold separately, so check our range if you need those too. Full fitting instructions are supplied with the kit.
Yes, correcting caster angle with this upper control arm keeps steering stability consistent when you're towing at a lifted ride height. It doesn't change load capacity or payload rating on its own — that's governed by your springs and shocks. For heavier towing setups, pair it with rear leaf springs or airbags rated for your constant load. Our team can help you match the whole suspension package to your trailer or caravan weight.
For most 2" to 3" lifts on the Colorado, yes — factory upper control arms run out of correct caster and camber range once the vehicle is raised. Left uncorrected, this causes CV joint stress, uneven tyre wear and reduced steering feel. This Blackhawk kit is designed to restore that geometry rather than leave the factory arms working outside their intended range. It's a standard companion part alongside any Colorado lift kit installation.
Yes, wheel alignment is mandatory after installing this upper control arm kit. Caster, camber and toe all change when the control arm geometry is corrected, so a proper four-wheel alignment is needed to set them to spec. We recommend a follow-up alignment check after around 500km once the bushes have settled in. Skipping alignment will lead to uneven tyre wear regardless of how good the arms are.
This kit is supplied as a fixed configuration with heavy-duty greasable ball joints and reinforced bushes as standard — there isn't a separate spring rate choice since this is a control arm, not a spring. If you're also selecting coil springs or leaf springs for your lift, those come in different load ratings depending on your accessory weight. Speak with our team about matching spring rate to your front-end accessories like a bull bar or winch. The control arm itself works across the standard 2" to 3" lift range.
Correcting the control arm geometry helps maintain proper wheel alignment and steering clearance once you've gone up in tyre size with a lift. Actual tyre clearance depends on your final lift height, wheel offset and tyre width, not the control arms alone. Most Colorado owners running a 2" to 3" lift can fit up to a 33-inch tyre with adequate clearance, but check your specific wheel and tyre combination. Our team can advise on tyre sizing once you've settled on a lift height.
This Blackhawk upper control arm kit is backed by a manufacturer warranty covering defects in materials and workmanship. Ball joints and bushes are the components most commonly checked under warranty claims, so keep your purchase details on hand. If you have any issue after fitting, our team can talk you through the warranty process. We dispatch from Australian stock, so replacement parts don't need to come from overseas.
Yes, this upper control arm kit is designed to restore normal steering feel and tyre wear patterns for daily-driven lifted Colorados, not just off-road use. Correcting caster angle actually improves on-road stability and steering return compared to running factory arms outside their design range. Tradespeople and commuters running a lifted Colorado for daily use commonly fit this as a standard part of the upgrade. It doesn't add noise or harshness to the ride on its own.
Sorted the geometry issues after my lift
Fitted these upper control arms after putting a 2-inch lift on my 2019 Colorado and the difference in steering and handling is night and day. The castor correction has made highway driving so much more confident, especially when loaded up with the camper trailer and kids' gear heading down to the coast. Installation was straightforward enough in the driveway with basic tools, and the build quality feels proper solid. Well worth it if you've lifted your Rads and want it driving properly again.(5)
