ReadyLIFT billet upper control arms (UCA) that are constructed from CNC-machined 6061 Aluminum.   New UCAs use forged chromoly bushing rod ends for extended durability. Teflon-lined, non-bonded dual durometer bushing prevents bushing binding. On-car adjustability provides an added level of flexibility and aids in the alignment process (Including a specific crowfoot wrench with each kit). To secure the on-car adjuster, the ReadyLIFT arm provides two pinch bolts that are fortified with a replaceable 4140 alloy nut that is recessed into the arm for a clean look while creating a functional self-retaining feature. Includes the ReadyLIFT Heavy Duty high angle ball joint that offers strength and reliability while providing more misalignment than a traditional off-road-only Uniball. O-ring sealed ball joint cap that is bolted in place for additional protection from the elements.
