ReadyLIFT Xtreme-Duty A-Arm Control Arm Kit For 11-19 Chevy/GMC 2500HD/3500HD

Upgrade your GM HD truck’s front suspension with the ReadyLIFT Xtreme-Duty Fabricated Upper Control Arms—engineered for 2011–2019 GM 2500HD and 3500HD models with 2"–8" of front lift. Constructed from laser-cut, tab-and-slot 4130 chromoly plate steel, these boxed control arms offer superior strength and rigidity for demanding off-road and towing conditions. The rugged design includes heavy-duty, spring-loaded high-angle ball joints that preserve proper alignment and articulation for lifted setups. Each arm is finished in a sleek Anthracite Gray powder coat and capped with CNC-machined billet aluminum covers to protect against harsh road debris.

These advanced control arms feature ReadyLIFT’s exclusive Terrain Control Technology (TCT) pivots—self-lubricating and maintenance-free for long-lasting performance. A free-floating inner bushing design with "side biter" washers helps maintain alignment and reduce bushing wear, ensuring your vehicle stays dialed in even under load. Built to handle the increased weight of oversized wheels and tires, these UCAs come complete with Grade 8 hardware and require no major modifications for installation. Whether you’re off-roading or towing heavy loads, this is the premium suspension upgrade your HD truck deserves.
