The Blackhawk UCA3881H-TOUR upper control arm kit fits Toyota Hilux N70 (KUN, 2005-2015), N80 (GUN, 2015-on) and Fortuner, and builds in 1 degree of caster increase - the touring specification, matched to mild lifts of around 1" to 2" where a full 3 degree correction would over-rotate the front end. Heavy-duty tubular arms run sealed bushings and greasable ball joints in place of the factory rubber bushes, cutting highway wander and uneven tyre wear. Direct bolt-on fitment at the factory mounting points, no drilling. If you are running a 2" to 3" lift kit, choose the 3 degree UCA3881H instead. In stock in Australia, backed by manufacturer warranty and fitment support from our team.

This kit is upper control arms only and doesn't include springs, but caster correction is usually fitted alongside a lift, so it pays to match your coil springs to your constant accessory load before you set final ride height. Front load-affecting accessories include bull bars, winches and driving light bars; rear load is affected by canopies, drawer systems, water tanks and touring accessories. Choosing the correct spring rate first means your caster correction settles at the ride height it was designed for.
Fitting these upper control arms is a straightforward bolt-on job for an experienced DIY installer, though we recommend professional fitment given the steering and alignment implications. Wheel alignment is mandatory after installation to set caster, camber and toe correctly — this is not optional with a caster correction arm. Re-check all fastener torques after the first 500km of driving. For a fully corrected front end, pair these arms with upgraded control arms front and rear where applicable, or review our full suspension components range.
Blackhawk4x4 builds suspension components specifically for Australian conditions, from corrugated outback tracks to daily bitumen commuting. Each Upper Control Arm is backed by a manufacturer warranty and is trusted by tradespeople and tourers running lifted Hilux N70s. You can view the full Blackhawk4x4 range to plan a complete suspension upgrade.
This kit suits Hilux N70 owners who've already fitted a lift kit and need the steering geometry corrected back to spec. It's a common fit for tradespeople carrying tools and equipment, caravan and camper trailer towers, and touring rigs running a bull bar and winch up front. Load carriers running heavier constant loads should also look at airbag suspension to keep rear ride height consistent.
In stock and ready to dispatch from our Australian warehouse, with fitment guidance from our in-house team on every order. Browse our full lift kit range to build a complete package with your caster correction arms.

This kit doesn't add lift height itself — it's designed to correct caster on a Hilux N70 that has already been lifted, typically in the 2"-3" range. The 3° of caster correction is built into the arm geometry, restoring the steering angle the factory engineered before the lift. If you're still choosing a lift height, browse our lift kit range first and select control arms to suit.
The kit includes two Blackhawk4x4 upper control arms (driver and passenger side), each with greasable ball joints and sealed heavy-duty bushings pre-fitted. Mounting hardware and fitting bolts are included, along with fitting instructions. Springs, shocks and lift kit components are sold separately.
Yes. Correcting caster angle improves steering stability and reduces wander, which is noticeable when towing a caravan or camper trailer at highway speed on a lifted Hilux N70. For heavier constant tow loads, pair this arm with the correct rear spring rate or an airbag suspension setup to keep ride height and geometry consistent while hooked up.
If your Hilux N70 has been lifted 2" or more, upgrading to a caster-correcting upper control arm like this one is strongly recommended. Lifting the vehicle without correcting caster leaves the steering geometry out of factory spec, causing wander and uneven tyre wear. This arm restores 3° of caster to bring the geometry back within an acceptable range for the lifted ride height.
Yes, wheel alignment is mandatory after installing these upper control arms. Caster, camber and toe all need to be set once the arms are fitted and the vehicle is at its final ride height. Skipping alignment will undo the benefit of the caster correction and can accelerate tyre wear.
This kit is control arms only and doesn't include springs, so spring rate selection is a separate decision. If you haven't already chosen your springs, look at our coil springs range and select a rate to suit your constant accessory load — bull bar and winch up front, canopy and drawers in the rear. Our team can help match a spring rate to this control arm and your lift height.
Correcting caster with this arm doesn't change tyre clearance on its own — that depends on the lift height and wheel offset you've already fitted. On a Hilux N70 lifted 2"-3", most owners running this arm are also running 33-inch tyres without rubbing, but clearance depends on wheel width and offset. Contact our team with your wheel and tyre specs for a clearance check specific to your setup.
This Blackhawk4x4 Upper Control Arm kit is covered by a manufacturer warranty against defects in materials and workmanship. Keep your proof of purchase and installation date on file, as most warranty claims require confirmation of correct fitment and alignment. Contact our team if you have any warranty questions before or after fitting.
Yes. Restoring correct caster with this arm actually improves on-road steering feel and reduces wander compared to driving a lifted Hilux N70 on uncorrected geometry. The sealed bushings and greasable ball joints hold up to daily commuting as well as touring and job-site use. It's a common fit for tradespeople and daily drivers running a lifted N70 who want the steering to feel like factory again.
Fixed the Wandering After Our Lift Kit
Put these upper control arms on after lifting our N70 for a trip down to the High Country and the difference was night and day. The steering finally feels tight and predictable again, which makes a huge difference when you're towing the camper trailer on corrugated dirt roads. Fitment was spot-on with the standard bushings, and they've held up perfectly through several months of weekend adventures.(5)
