Built To Handle Heavy Duty Abuse Without Compromise

If your 2020-2026 GM Silverado or Sierra HD spends more time hauling, towing, or pushing through rough terrain than sitting parked in the driveway, these ReadyLIFT Xtreme-Duty Upper Control Arms are exactly the kind of upgrade that makes a difference you can actually feel. Built from fabricated 4130 chromoly steel, these control arms are designed to handle the added stress that comes with oversized tires, heavy wheels, and leveled or lifted suspension setups. The high-angle heavy-duty ball joints help maintain smooth suspension movement while giving your truck the strength it needs for demanding daily use. Additionally, the corrected pivot cup design helps improve suspension geometry so your truck drives confidently without feeling sloppy or unpredictable after a lift. ReadyLIFT also includes self-lubricating TCT bushings that are engineered to reduce friction and hold up longer than traditional designs. That means less wear over time and fewer headaches when your truck sees rough roads, jobsite miles, or long highway drives pulling a trailer. Finished in a rugged anthracite gray powder coat with billet aluminum ball joint caps, these control arms bring serious durability along with a clean aggressive appearance that looks right at home under any HD truck build.

Precision Engineered Strength For Modern GM HD Trucks

ReadyLIFT designed these Xtreme-Duty upper control arms specifically for 2020-2026 Silverado and Sierra 2500HD and 3500HD trucks that demand improved suspension performance without sacrificing everyday drivability. Each arm starts with laser-cut and CNC-bent .125-inch 4130 chromoly plate steel, creating an extremely rigid structure capable of standing up to harsh suspension loads. The frame side pivots feature ReadyLIFT proprietary TCT bushings with a free-floating inner sleeve design that helps eliminate friction, which is one of the leading causes of premature bushing failure. What's more, the integrated side-biter washers help maintain proper alignment settings during aggressive driving and off-road use. The 1-ton spring-loaded ball joints are engineered for increased articulation angles while still preserving factory-like steering feel and suspension control. To further improve durability, ReadyLIFT protects the ball joints with CNC-machined billet aluminum caps that help shield critical components from salt, sand, mud, and road debris. Compatible with both 2WD and 4WD trucks using leveling kits or suspension lifts, these fabricated upper control arms deliver the added strength and long-term reliability serious HD owners expect from a premium suspension upgrade.
