ReadyLift Xtreme-Duty Fabricated A-Arm Kit - GM Silverado / Sierra 2500HD/3500HD 2011-2019

• All-new Xtreme-Duty fabricated upper control arms (UCAs), the same rugged fabrication used in ReadyLift’s 3" SST Lift Kit, designed for 2011–2019 GM Silverado/Sierra 2500HD/3500HD; 2WD and 4WD.
• Precision construction: laser-cut and CNC-bent.125" 4130 chromoly plate steel for exceptional strength and long‑term durability.
• 1-ton spring-loaded high-angle HD series ball joints maintain factory driving feel while handling the added weight of aftermarket wheels and tires.
• CNC-machined billet aluminum caps shield the joints from road debris, extending life in harsh working environments.
• Frame-side pivots feature proprietary TCT bushings that are self-lubricating and include side biter washers to help maintain alignment; the free-floating design reduces friction and wear.
• Anthracite Gray powder coat finish with a stainless steel ReadyLIFT arm badge for rugged durability and a clean, professional appearance.
• Designed for use with or without existing leveling or lift kits (kits sold separately) to upgrade durability and performance without compromising ride quality.
