Xtreme-Duty Fabricated Upper Control Arm Kit

The ReadyLift 67-30320 Xtreme-Duty Fabricated A-Arm Kit is engineered for 2020-2025 GM Silverado/Sierra 2500HD/3500HD 2WD/4WD vehicles that are leveled or lifted. Constructed from robust 4130 chromoly plate steel, these upper control arms feature corrected pivot cups to optimize geometry in modified suspension setups. The kit includes ReadyLIFT's stronger, longer-lasting outer and inner TCT pivot bushings, along with high-angle heavy-duty ball joints, ensuring enhanced durability and performance. The pivots are designed to be self-lubricating with a free-float inner sleeve and side-biter washers, contributing to improved alignment maintenance. Finished with an anthracite gray powder coat, these A-arms also include CNC machined billet aluminum caps for ball joint protection and a stainless steel ReadyLIFT brand arm badge. Installation of the ReadyLift 67-30320 is estimated to take approximately 2 hours, excluding alignment and wheel/tire assembly. While designed for easy installation, professional alignment after installation is recommended to ensure optimal vehicle handling and tire wear. Tools required for installation are standard automotive hand tools, and no factory parts are permanently modified, allowing for a return to stock if desired. Compatibility extends to both 2WD and 4WD configurations of the specified GM HD trucks. It is important to note that this kit is not suitable for stock ride height trucks and is specifically designed for lifted or leveled applications. The manufacturer has also indicated that the Single Cab configuration has not been validated for fitment and drivability. The 4130 chromoly plate steel construction offers superior strength compared to factory components, providing increased resistance to bending and fatigue. The TCT pivot bushings are engineered for extended lifespan and reduced maintenance. The high-angle heavy-duty ball joints accommodate the increased suspension articulation often found in lifted applications, preventing premature wear and tear. This kit aims to correct suspension geometry issues that can arise with lifted trucks, restoring proper handling and ride characteristics.
