The Blackhawk Ultimate Adjustable Upper Control Arm Kit (BHU3841P) suits the Toyota Land Cruiser Prado 120 Series (2002-2009), Prado 150 Series (2009-on) and FJ Cruiser (2007-2016) running a 2" to 3" lift, correcting caster and camber back toward factory specification. Heavy-duty arms with sealed ball joints replace the factory stamped-steel units and hold adjustment through corrugations and mud that would flush out an unsealed bush. Pair them with our coil springs for a fully corrected front end at ride height. Caster and camber are set on the vehicle using the Blackhawk Ultimate adjustment spanner. Backed by full manufacturer warranty, Australian stock and fitment support from our team.

These are control arms, not springs, so they don't add lift on their own. What matters is how much lift you're already running: a 2" lift typically uses up most of the factory caster adjustment range, while a 3" lift pushes well past it, which is where an adjustable arm becomes necessary rather than optional. If you're planning a lift and haven't chosen your lift kit yet, tell our team the target height so we can confirm whether adjustable arms are needed on your setup.
Fitment is a bolt-on job at the factory upper control arm mounting points, but we recommend an experienced 4WD workshop or qualified fitter carry out the install given the torque specs and alignment work involved. A full wheel alignment is mandatory after fitting — the cam bolts need to be set within spec by an aligner, not just torqued up by feel. Allow a 500km settling period before a final alignment check, as bushings and joints seat in under normal driving. For a fully corrected front end, pair this kit with lower control arm upgrades if your lift height requires them.
Blackhawk4x4 builds its suspension components for the loads and terrain Australian 4WD owners actually deal with, and this control arm kit is tested locally rather than adapted from a market with different conditions. It comes with a full manufacturer warranty and is stocked here in Australia, so you're not waiting on an overseas shipment to get your Prado or FJ Cruiser back on the road. Tourers and tradespeople running lifted 120 Series and FJ Cruiser 4WDs use this kit specifically to stop the caster-related tyre wear that shows up within a few thousand kilometres of a lift. You can view the full Blackhawk4x4 range for matching shocks and springs.
This kit is for Prado 120 and FJ Cruiser owners who've already fitted, or are about to fit, a 2" to 3" lift and are seeing steering pull, inside-edge tyre wear, or an alignment shop unable to get caster back in spec. It suits tourers running a loaded rig and tradespeople with constant tray or canopy weight up front, where correct geometry matters more than on an unladen daily driver. If you're carrying variable loads rather than a constant one, our airbag suspension range is worth a look alongside this kit.
In stock in Australia and dispatched fast, with our team on hand to confirm fitment for your exact Prado 120 or FJ Cruiser build before you order. Browse our full lift kit range to match shocks and springs to this control arm upgrade.

Yes, this Blackhawk Ultimate Adjustable Upper Control Arm Kit is built specifically for the Toyota Prado 120 Series (2002-2009) and FJ Cruiser (2007-2016). It bolts into the factory upper control arm mounting points on both vehicles. If your Prado or FJ Cruiser has aftermarket steering or suspension modifications, contact our team first to confirm compatibility before you order.
This kit doesn't add lift on its own — it's a control arm, not a spring. It's designed to correct the caster and camber angles created once your Prado 120 or FJ Cruiser is running a 2" to 3" lift kit. If you're still choosing a lift height, our team can tell you at what point adjustable arms become necessary for your specific setup.
The kit includes two Blackhawk Ultimate Adjustable Upper Control Arms with sealed ball joints pre-fitted, cam-style adjustment bolts for caster and camber, and the mounting hardware needed for installation. Lower control arms and coil springs are sold separately. A fitment and torque instruction sheet is included with every kit.
Yes. Correcting caster and camber after a lift improves steering stability and tyre contact, which matters when you're towing a loaded trailer or caravan. The control arms themselves don't carry load like a spring does, so pair this kit with correctly rated coil springs to handle your actual tow ball weight and payload.
If your Prado 120 or FJ Cruiser is running a 2" lift or more, factory upper control arms usually can't provide enough caster adjustment to bring alignment back into spec. That's when adjustable arms like this kit become necessary rather than optional. Signs you need them include an aligner telling you caster is out of range, or visible inside-edge tyre wear after a lift.
Yes, a full wheel alignment is mandatory after fitting this kit. The cam-style adjustment bolts need to be set within manufacturer specification by a qualified aligner, not just torqued up by feel. We recommend a settling period of around 500km before a final alignment check once bushes and joints have seated in.
This is a control arm kit, not a spring kit, so spring rate selection doesn't apply directly here. If you need spring rates matched to a bull bar, winch or constant canopy load, browse our coil spring range and our team can match a rate to your accessory load alongside this control arm upgrade.
This control arm kit doesn't change tyre clearance by itself — that comes from the lift kit fitted to the vehicle. What this kit does is keep steering geometry correct once larger tyres and a lifted stance are in place, reducing the uneven wear that oversized tyres can accelerate on a misaligned front end. Talk to us about tyre size versus your specific lift height before fitting.
This Blackhawk Ultimate Adjustable Upper Control Arm Kit is backed by a full manufacturer warranty covering defects in materials and workmanship. It's stocked and dispatched from within Australia, so warranty support and replacement parts don't require an overseas wait. Contact our team directly if you have any warranty questions specific to your Prado or FJ Cruiser.
Yes. Correcting caster and camber with this kit is what makes a lifted Prado 120 or FJ Cruiser drive properly on-road, reducing steering pull and uneven tyre wear compared with running factory-limited adjustment on a lifted vehicle. It's a common fitment for daily-driven tourers and tradies, not just occasional off-road use.
