      Extreme-Duty Upper Control Arms. Designed to be used on 2500 GMC Sierras with a 2 to 8-inch of front lift from qualified ReadyLIFT lift kit, these ReadyLIFT Extreme-Duty Upper Control Arms provide the correct ball joint pivot angle for lifted applications.

      Fabricated Steel Construction. ReadyLIFT manufactures their Control Arms using their very own time-tested fabricated steel design technology. Laser cut and CNC bent from .125 4130 chromoly plate steel, these Upper Control Arms employee a tab and slot boxed design to increase overall strength and durability. The Control Arms are then completed in an anthracite gray powdercoat finish for good looks and long lasting corrosion resistance.

      HD Series Ball Joints. The critical pivot points are maintenance-free and extremely durable for long-lasting use. One-ton spring loaded HD series ball joints maintain the factory driving experience and can take a beating. To protect the joints from road debris, the arms include CNC machined billet aluminum caps which helps extend the life of the ball joints.

      Terrain Control Technology. Frame side pivots feature ReadyLIFT's new Terrain Control Technology (TCT) bushings are maintenance free and self lubricating. These new bushings include a new "free float" inner bushing with "side biter" washers to aid in maintaining alignment settings. The free-floating bushing design eliminates friction which is the most common culprit of traditional bushing failure.

      Bolt-on Installation. ReadyLIFT designed their Xtreme-Duty Fabricated A-Arm Kit to be a straight forward bolt-on install with no major modifications required. With all the necessary hardware included, this A-Arm Kit can be installed in about 3 hours time. Please note that an alignment is required after installation.

      Application. This ReadyLIFT Xtreme-Duty Fabricated A-Arm Kit for 2 to 8-Inch Lift is designed to fit 2011-2019 GMC Sierra 2500 HD models with a 2 to 8-Inch Front Lift. Please note that these Control Arms are not designed for use on a stock ride height vehicle.
