Sierra 1500 AT4 / AT4X 2019-2026 GMC 4WD Forged Upper Control Arms (OE Upgrade) by Rough Country

The Rough Country 10018 Forged Upper Control Arms are a premium OE upgrade for your 2019–up GMC Sierra 1500 AT4 / AT4X 4WD, delivering increased strength, improved articulation, and long-lasting durability. Designed as a direct bolt-on replacement, these control arms outperform factory components.

Constructed from a solid one-piece forged aluminum design, these upper control arms eliminate weak points commonly found in welded assemblies. The result is superior structural strength capable of handling larger tires, added suspension stress, and demanding driving conditions on-road or off-road.

Each arm is equipped with POM ball joints that reduce metal-to-metal contact for smoother operation, less maintenance, and longer service life compared to standard OE replacements. The oversized ball joint design improves range of motion and articulation, making these an excellent upgrade for lifted applications. Fully greaseable joints allow for easy servicing and long-term reliability.

To preserve ride quality and reduce unwanted vibration, these control arms also feature durable OEM-style rubber bushings, offering the ideal balance of comfort and strength for daily driving or off-road use.

With a simple 100% bolt-on installation and backed by Rough Country’s Limited Lifetime Replacement Warranty, these forged control arms are built to perform for years to come.
