The Blackhawk4x4 forged radius arms will strengthen your vehicle, stop it wandering and keep it straight. ADR compliant, including GVM upgrades with front axle up to 1660kg. Supplied with Australian made hybrid rubber bushings, guaranteed for the life of your purchase. Forged from a single piece of Chromoly steel to the right profile followed up with a specific heat treating program to provide the same yield & tensile material properties as BIS80 - but with greater ductility (Elastic) meaning they will bend compared to a break just like OE Toyota. After heat treating the arms then undergo CNC machining for accurate bush location.
