Dirt King Fabrication 4130 Ball Joint Upper Control Arms 2009-2018 Ram 1500 4wd | DK-541993

Dirt King’s 4130 Upper Control Arms (DK‑541993) are precision-engineered for 2009–2018 Ram 1500 4WD models. Constructed from high-strength 4130 chromoly tubing and professionally MIG‑welded in the USA, these preassembled arms are designed to maintain proper suspension alignment from 0–2.5″ of lift—and add roughly 1″ of down‑travel compared to the stock setup. They include maintenance‑free SilentSpin™ bushings that eliminate grease fittings and nuisance noises, along with heavy‑duty Probearing Pro 4 ball joints sealed against debris for maximum articulation and durability.

Whether you're daily driving or pushing your rig through overlanding, rock‑crawling, or desert runs, these UCAs deliver improved caster and pivot geometry for smoother handling with up to 2.5″ of lift. Fully rebuildable design, corrosion‑resistant powder‑coated finish, zinc‑plated hardware, and a kit that ships complete with all necessary bolts and a Dirt King sticker pack make installation straightforward and long‑lasting
