Upgrade your suspension with Dirt King upper control arms, the ultimate performance upgrade for your Toyota 4Runner. Designed to fit 2003–2024 4Runner (2WD or 4WD) models, these Toyota 4Runner upper control arms are built from 4130 chromoly and engineered to fix common issues like squeaky bushings, high-maintenance joints, and misaligned suspension geometry after adding a lift. Whether your 4Runner is a daily driver, overland rig, rock crawler, or desert explorer, these 4Runner upper control arms deliver unmatched strength, performance, and reliability.

Each set of Dirt King upper control arms features maintenance-free SilentSpin™ bushings that eliminate grease fittings and unwanted noise, plus heavy-duty Probearing Pro 4 ball joints for maximum articulation and durability. The sealed ball joints keep out dirt and debris, while anodized caps add extra protection. Designed to maintain proper alignment from 0–3″ of lift, these arms also add approximately one inch of additional down travel—perfect for pairing with aftermarket coilovers like Fox, King, or Ride Shocks.
