When you install a lift kit on your Landcruiser 300 Series, the front suspension geometry changes significantly. Stock upper control arms become too short, pushing the top of the wheel inward and creating negative camber. This causes uneven tyre wear, reduced steering response, and compromised handling both on and off-road. Blackhawk Upper Control Arms restore correct camber and caster angles, ensuring your 300 Series tracks straight, wears tyres evenly, and maintains factory steering precision even with 2-3 inches of front lift.
Professional installation by a qualified 4WD mechanic or experienced DIY installer is recommended. Upper control arm replacement requires spring compression and suspension disassembly—proper safety equipment and spring compressor tools are mandatory. A full four-wheel alignment is absolutely essential after fitting to set camber, caster, and toe to manufacturer specifications. We recommend pairing these control arms with quality shock absorbers and coil springs for a complete front-end upgrade that maximizes both performance and longevity.

This upper control arm kit is ideal for Landcruiser 300 Series owners who have already installed or are planning to install a suspension lift, and want to maintain correct front-end geometry and steering precision. Whether you're a touring family with a rooftop tent and long-range tanks, a tradie hauling heavy loads daily, or a weekend warrior tackling Cape York and the Simpson Desert, these control arms are essential for safe, predictable handling. For owners carrying constant heavy loads, consider pairing with airbag suspension in the rear to maintain level stance and ride comfort.

Yes, this Blackhawk Upper Control Arm kit (UCA4861T) is specifically engineered to fit all Toyota Landcruiser 300 Series models from 2021 onwards, including both the 3.3L V6 turbo diesel and 3.5L V6 twin-turbo petrol variants. The kit is a direct bolt-in replacement using factory mounting points, requiring no modifications to your vehicle. It suits both GX, GXL, VX, and Sahara trim levels. If you have aftermarket front-end accessories like a bull bar or winch, these control arms are designed to handle the additional weight while maintaining correct suspension geometry.
Yes, upper control arms are highly recommended—and often essential—when lifting a Landcruiser 300 Series by 2 inches or more. Stock control arms cannot compensate for the increased ride height, resulting in negative camber (wheels tilting inward at the top), which causes premature inner tyre wear, reduced steering precision, and compromised handling. Blackhawk Upper Control Arms restore correct camber and caster angles, ensuring your lifted 300 Series drives straight, wears tyres evenly, and maintains safe, predictable on-road and off-road performance. Without upgraded control arms, you risk uneven tyre wear and poor handling characteristics.
The kit includes everything needed to replace both front upper control arms: 2 x Blackhawk Upper Control Arms with OE-style rubber bushings already pressed in, 2 x Roadsafe Heavy-Duty Ball Joints pre-fitted and torqued to specification, 4 x hardened steel washers, 2 x Blackhawk ball joint dust caps, and 2 x sealing O-rings for dust cap protection. The ball joints and bushings arrive pre-installed, saving you time and eliminating the need for press work during installation. You'll need to reuse your factory mounting hardware or source new OEM bolts and nuts from Toyota for the installation.
Absolutely. Blackhawk Upper Control Arms are engineered with heavy-duty forged steel construction and Roadsafe HD ball joints to handle the increased front-end weight from bull bars, winches, long-range fuel tanks, and other touring accessories. The reinforced design maintains correct suspension geometry and steering response even under constant heavy loads, making them ideal for caravan and camper trailer towing, trade use, and long-distance touring. For rear load support, we recommend pairing these control arms with quality airbag suspension or upgraded rear springs to maintain level vehicle stance and optimal handling balance.
Yes, a full four-wheel alignment is absolutely mandatory after installing upper control arms. Replacing control arms changes front-end geometry, and only a qualified alignment technician can correctly set camber, caster, and toe angles to manufacturer specifications. Driving without proper alignment will result in uneven tyre wear, poor handling, and potentially unsafe steering characteristics. Most reputable 4WD workshops include alignment in their installation quote. We strongly recommend booking alignment immediately after fitment to ensure your 300 Series tracks straight and delivers optimal performance.
While these Blackhawk Upper Control Arms will physically bolt onto a standard-height 300 Series, they are specifically designed to correct geometry issues caused by lifting. If your vehicle is still at factory ride height, the stock upper control arms are adequate and there's no performance benefit to upgrading. However, if you're planning a lift kit installation in the near future, purchasing control arms now can save on double-handling installation costs. We recommend fitting control arms at the same time as your lift kit for maximum efficiency and immediate geometry correction.
Upper control arm replacement requires intermediate to advanced mechanical skills, proper safety equipment, and specialized tools including a coil spring compressor. The installation involves partially disassembling the front suspension, removing compressed coil springs, and safely handling heavy steering and suspension components. If you have experience with suspension work, appropriate tools, and a safe workshop environment, DIY installation is possible. However, most 300 Series owners choose professional installation by a qualified 4WD mechanic to ensure correct fitment, torque specifications, and mandatory post-installation wheel alignment.
Blackhawk4x4 backs this Upper Control Arm kit with a comprehensive manufacturer's warranty covering defects in materials and workmanship. The pre-fitted Roadsafe ball joints also carry their own warranty protection. Warranty terms apply to normal 4WD use including touring, towing, and off-road driving when installed correctly and maintained according to manufacturer guidelines. For specific warranty duration and claim process details, please contact our team or refer to the warranty documentation included with your kit. Australian consumer law protections also apply to all products sold through 4WD Suspension.
Upper control arms themselves don't create tyre clearance—they restore correct suspension geometry after lifting. The tyre size you can fit depends on your total lift height (springs and shocks), wheel offset, and any body modifications. Most 300 Series owners running a 2-3 inch lift with Blackhawk Upper Control Arms can safely fit 33-inch tyres with minimal to no rubbing. For larger 35-inch tyres, additional modifications such as guard trimming, body lifts, or aftermarket front bars may be required. Always test-fit tyres at full lock and full compression before committing to a size upgrade.
Yes, significantly. By restoring correct suspension geometry after lifting, Blackhawk Upper Control Arms allow your front wheels to maintain better contact with the ground during articulation, improving traction on uneven terrain. The extended ball joint range provides greater suspension travel, helping each wheel independently follow contours and obstacles. Correct camber and caster angles also improve steering feedback and precision on technical tracks, sand, and rock crawling. Combined with quality shocks and springs, upgraded control arms are a critical component in maximizing your 300 Series' off-road capability and driver confidence.
